Export To Excel in WPF DataGrid (SfDataGrid)

6 Sep 202324 minutes to read

WPF DataGrid provides support to export data to excel. It also provides support for grouping, filtering, sorting, paging, unbound rows, merged cells, stacked headers and Details View while exporting.

The following assemblies needs to be added for exporting to excel.

• Syncfusion.SfGridConverter.WPF
• Syncfusion.XlsIO.Base

For NuGet package, have to install Syncfusion.DataGridExcelExport.WPF package. For more details refer this UG link.

You can export SfDataGrid to excel by using the ExportToExcel extension method present in the Syncfusion.UI.Xaml.Grid.Converter namespace.

C#

using Syncfusion.UI.Xaml.Grid.Converter;
var options = new ExcelExportingOptions();
options.ExcelVersion = ExcelVersion.Excel2013;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

NOTE

SfDataGrid exports data to excel by using XlsIO. You can refer XlsIO documentation for manipulating exported work sheets.

Excel exporting options

Exporting operation can be customized by passing ExcelExportingOptions instance as argument to ExportToExcel method.

Export mode

By default, actual value only will be exported to excel. If you want to export the display text, you need to set ExportMode property as Text.

C#

var options = new ExcelExportingOptions();
options.ExportMode = ExportMode.Text;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

Export groups with outlines

By default, all the groups in dataGrid will be exported in expanded state. You can enable outlines in excel based on groups by setting the AllowOutlining property as true in ExcelExportingOptions. 

C#

var options = new ExcelExportingOptions();
options.AllowOutlining = true;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

Exclude columns while exporting

By default, all the columns (including hidden columns) in SfDataGrid will be exported to Excel. If you want to exclude some columns while exporting to Excel, you can use ExcludeColumns field in ExcelExportingOptions.

C#

var options = new ExcelExportingOptions();
options.ExcludeColumns.Add("CustomerName");
options.ExcludeColumns.Add("Country");
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

Here, the columns having CustomerName and Country as MappingName are excluded while exporting.

Excel version

While exporting to Excel, you can specify the excel version by using ExcelVersion property.

C#

var options = new ExcelExportingOptions();
options.ExcelVersion = ExcelVersion.Excel2013;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

Exporting stacked headers

You can export stacked headers to excel by setting ExportStackedHeaders property to true.

C#

var options = new ExcelExportingOptions();
options.ExportStackedHeaders = true;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

Exporting merged cells

You can export merged cells to excel by setting ExportMergedCells property as true.

C#

var options = new ExcelExportingOptions();
options.ExportMergedCells = true;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

Exporting unbound rows

You can export unbound rows to excel by setting ExportUnBoundRows property as true.

C#

var options = new ExcelExportingOptions();
options.ExportUnBoundRows = true;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

Changing start row and column index while exporting

You can export the data to specified row index and column index in worksheet, by setting StartRowIndex and StartColumnIndex properties.

C#

var options = new ExcelExportingOptions();
options.StartColumnIndex = 3;
options.StartRowIndex = 3;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

Saving options

Save directly to file

After exporting to excel, you can save exported workbook directly to file system by using SaveAs method.

C#

var options = new ExcelExportingOptions();
options.ExcelVersion = ExcelVersion.Excel2013;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

Save as stream

After exporting to excel, you can save exported workbook to stream by using SaveAs method.

C#

var options = new ExcelExportingOptions();
options.ExcelVersion = ExcelVersion.Excel2013;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
FileStream fileStream = new FileStream("Output.xlsx", FileMode.Create);
workBook.SaveAs(fileStream);

You can refer XlsIO documentation.

Save using File dialog

After exporting to excel, you can save exported workbook by opening FileDialog.

C#

var options = new ExcelExportingOptions();
options.ExcelVersion = ExcelVersion.Excel2013;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];

SaveFileDialog sfd = new SaveFileDialog
{
    FilterIndex = 2,
    Filter = "Excel 97 to 2003 Files(*.xls)|*.xls|Excel 2007 to 2010 Files(*.xlsx)|*.xlsx|Excel 2013 File(*.xlsx)|*.xlsx"
};

if (sfd.ShowDialog() == true)
{
    using (Stream stream = sfd.OpenFile())
    {

        if (sfd.FilterIndex == 1)
            workBook.Version = ExcelVersion.Excel97to2003;

        else if (sfd.FilterIndex == 2)
            workBook.Version = ExcelVersion.Excel2010;

        else
            workBook.Version = ExcelVersion.Excel2013;
        workBook.SaveAs(stream);
    }

    //Message box confirmation to view the created workbook.

    if (MessageBox.Show("Do you want to view the workbook?", "Workbook has been created",
                        MessageBoxButton.YesNo, MessageBoxImage.Information) == MessageBoxResult.Yes)
    {

        //Launching the Excel file using the default Application.[MS Excel Or Free ExcelViewer]
        System.Diagnostics.Process.Start(sfd.FileName);
    }
}

Opening exported excel without saving

You can open the exported workbook without saving by using SfSpreadsheet control.

C#

var options = new ExcelExportingOptions();
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
Window window1 = new Window();
SfSpreadsheet spreadsheet = new SfSpreadsheet();
spreadsheet.Open(workBook);
window1.Content = spreadsheet;
window1.Show();

Export DataGrid pages to Excel

While exporting data to excel, if paging is used, current page only will be exported, by default. If you want to export all pages, you need to set ExportAllPages property as true.

C#

var options = new ExcelExportingOptions();
options.ExportAllPages = true;            
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

By default, all data will be exported to single sheet. If you want to export each page to different sheets, you need to use ExportPageOptions property.

C#

var options = new ExcelExportingOptions();
options.ExportAllPages = true;
options.ExportPageOptions = ExportPageOptions.ExportToDifferentSheets;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

Export DataGrid SelectedItems to Excel

By default, entire grid will be exported to Excel. You can export selected items only by passing SelectedItems to
ExportToExcel method.

C#

var options = new ExcelExportingOptions();
ExcelEngine excelEngine = new ExcelEngine();
IWorkbook workBook = excelEngine.Excel.Workbooks.Create();
workBook.Worksheets.Create();
dataGrid.ExportToExcel(dataGrid.SelectedItems, options, workBook.Worksheets[0]);
workBook.Version = ExcelVersion.Excel2013;
workBook.SaveAs("Sample.xlsx");

Export DataGrid to HTML

You can save exported workbook as HTML by using SaveAsHtml method.

C#

var options = new ExcelExportingOptions();
options.ExcelVersion = ExcelVersion.Excel2013;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAsHtml("Sample.html", HtmlSaveOptions.Default);

It is also possible to save worksheet as HTML by using SaveAsHtml method. You can refer XlsIO documentation for this.

Export DataGrid to Mail

You can export SfDataGrid to mail by converting it into Excel and save exported worksheet as HTML. Then exported HTML contents is embedded in mail body.

C#

var options = new ExcelExportingOptions();
options.ExcelVersion = ExcelVersion.Excel2010;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];

workBook.Worksheets[0].UsedRange.BorderInside(ExcelLineStyle.Thick, ExcelKnownColors.Black);
workBook.Worksheets[0].UsedRange.BorderAround(ExcelLineStyle.Thick, ExcelKnownColors.Black);
workBook.Worksheets[0].SaveAsHtml("test.htm", Syncfusion.XlsIO.Implementation.HtmlSaveOptions.Default);

System.Net.Mail.MailMessage myMessage = new System.Net.Mail.MailMessage();

myMessage.To.Add("[e-mail]");
myMessage.From = new MailAddress("[e-mail]");
myMessage.Priority = MailPriority.High;
myMessage.Subject = "Order Details";
myMessage.IsBodyHtml = true;
myMessage.Body = new StreamReader("test.htm").ReadToEnd();

SmtpClient client = new SmtpClient("smtp.office365.com", 587);

client.EnableSsl = true;
client.UseDefaultCredentials = false;
client.Credentials = new NetworkCredential("[e-mail]", "test");

int count = 0;

while (count < 3)
{

    try
    {
        client.Send(myMessage);
        count = 3;
    }

    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
        Console.WriteLine(String.Format("Sending Mail Attemp - {0}", count.ToString()));
        Thread.Sleep(60000);
        count++;
    }
}
Console.WriteLine("Mail has been sent...");

Export DataGrid to XML

You can save exported workbook as Xml file also by using SaveAsXml methods.

C#

var options = new ExcelExportingOptions();
options.ExcelVersion = ExcelVersion.Excel2013;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAsXml("Sample.xml", ExcelXmlSaveType.MSExcel);

Export DataGrid to CSV

You can save exported workbook as CSV by using SaveAs method.

C#

var options = new ExcelExportingOptions();

var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.csv", ",");

Similarly, you can save exported worksheet also to CSV. You can refer XlsIO documentation.

Row Height and Column Width customization

After exporting data to excel, you can set different row height and column width for the columns based on your requirement. You can refer here for more information.

C#

var options = new ExcelExportingOptions();
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.Worksheets[0].SetRowHeight(2, 50);
workBook.Worksheets[0].SetColumnWidth(2, 50);
workBook.SaveAs("Sample.xlsx");

Styling cells based on CellType in Excel

You can customize the cell styles based on CellType by using ExportingEventHandler.

C#

var options = new ExcelExportingOptions();
options.ExportingEventHandler = ExportingHandler;
options.AllowOutlining = true;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

private static void ExportingHandler(object sender, GridExcelExportingEventArgs e)
{

      if (e.CellType == ExportCellType.HeaderCell)
      {
          e.CellStyle.BackGroundBrush = new SolidColorBrush(Colors.LightPink);
          e.CellStyle.ForeGroundBrush = new SolidColorBrush(Colors.White);
          e.Handled = true;
      }

      else if (e.CellType == ExportCellType.RecordCell)
      {
          e.CellStyle.BackGroundBrush = new SolidColorBrush(Colors.LightSkyBlue);
          e.Handled = true;
      }

      else if (e.CellType == ExportCellType.GroupCaptionCell)
      {
          e.CellStyle.BackGroundBrush = new SolidColorBrush(Colors.Wheat);
          e.Handled = true;
      }
}

Cell customization in Excel while exporting

You can customize the cells by setting CellsExportingEventHandler in ExcelExportingOptions.

Customize cell value while exporting

You can customize the call values while exporting to excel by using CellsExportingEventHandler and ExcelExportingOptions.

C#

var options = new ExcelExportingOptions();
options.CellsExportingEventHandler = CellExportingHandler;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

private static void CellExportingHandler(object sender, GridCellExcelExportingEventArgs e)
{            

     // Based on the column mapping name and the cell type, we can change the cell 
                                          //values while exporting to excel.
     if (e.CellType == ExportCellType.RecordCell && e.ColumnName == "IsClosed")
     {

         //if the cell value is True, "Y" will be displayed else "N" will be displayed.

         if (e.CellValue.Equals(true))
             e.Range.Cells[0].Value = "Y";

         else
             e.Range.Cells[0].Value = "N";
         e.Handled = true;
      }
}

Here, cell values are changed for IsClosed column based on custom condition.

Changing row style in excel based on data

You can customize the rows based on the record values by using CellsExportingEventHandler.

C#

var options = new ExcelExportingOptions();
options.CellsExportingEventHandler = CellExportingHandler;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

private static void CellExportingHandler(object sender, GridCellExcelExportingEventArgs e)
{           

     if (!(e.NodeEntry is RecordEntry))
        return;
     var record = e.NodeEntry as RecordEntry;

     if ((record.Data as OrderInfo).Country == "Mexico")
     {
         e.Range.CellStyle.ColorIndex = ExcelKnownColors.Green;
         e.Range.CellStyle.Font.Color = ExcelKnownColors.White;
     }
}

Here, records having the Country name as Mexico are customized.

Customize the cells based on Column Name

You can customize the cells based on GridCellExcelExportingEventArgs.ColumnName property in the CellsExportingEventHandler.

C#

var options = new ExcelExportingOptions();
options.CellsExportingEventHandler = CellExportingHandler;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

private static void CellExportingHandler(object sender, GridCellExcelExportingEventArgs e)
{

    if (e.ColumnName != "OrderID")
        return;

    e.Range.CellStyle.Font.Size = 12;
    e.Range.CellStyle.Font.Color = ExcelKnownColors.Pink;
    e.Range.CellStyle.Font.FontName = "Segoe UI";
}

Here, OrderID column cells are customized while exporting.

Customize exported workbook and worksheet

SfDataGrid exports to excel by using XlsIO. You can refer XlsIO documentation for manipulating workbook and sheet after exporting.

Workbook

SfDataGrid provides option to return ExcelEngine from that you can get exported workbook. This allows you to protect, encrypt and add worksheet before saving.

C#

var options = new ExcelExportingOptions();         
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

Worksheet customization

SfDataGrid provides support to export to already existing file or worksheet.

In the below code snippet, worksheet is created and passed to ExportToExcel method. In the same way, you can open already existing excel also using XlsIO.

C#

var options = new ExcelExportingOptions();
ExcelEngine excelEngine = new ExcelEngine();
IWorkbook workBook = excelEngine.Excel.Workbooks.Create();
dataGrid.ExportToExcel(dataGrid.View, options, workBook.Worksheets[0]);
workBook.Version = ExcelVersion.Excel2013;
workBook.SaveAs("Sample.xlsx");

Before saving workbook, you need to set the specific excel version by using IWorkbook.Version property. Here, you can directly manipulate the data in the worksheet. You can refer here for more information.

Setting borders

You can set borders to excel cells by directly accessing worksheet after exporting data.

C#

var options = new ExcelExportingOptions();
options.ExcelVersion = ExcelVersion.Excel2013;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.Worksheets[0].UsedRange.BorderInside(ExcelLineStyle.Dash_dot, ExcelKnownColors.Black);
workBook.Worksheets[0].UsedRange.BorderAround(ExcelLineStyle.Dash_dot, ExcelKnownColors.Black);
workBook.SaveAs("Sample.xlsx");

Enabling Filters

You can show filters in exported worksheet by enabling filter for the exported range in the worksheet.

C#

var options = new ExcelExportingOptions();
options.ExcelVersion = ExcelVersion.Excel2013;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.Worksheets[0].AutoFilters.FilterRange = workBook.Worksheets[0].UsedRange;
workBook.SaveAs("Sample.xlsx");

While using stacked headers, you can specify the range based on Stacked headers count.

C#

var options = new ExcelExportingOptions();
options.ExcelVersion = ExcelVersion.Excel2013;
options.ExportStackedHeaders = true;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
var range = "A" + (dataGrid.StackedHeaderRows.Count + 1).ToString() + ":" + workBook.Worksheets[0].UsedRange.End.AddressLocal;
excelEngine.Excel.Workbooks[0].Worksheets[0].AutoFilters.FilterRange = workBook.Worksheets[0].Range[range];
workBook.SaveAs("Sample.xlsx");

You can refer XlsIO documentation.

Customize the range of cells

You can customize the range of cells after exporting to excel by directly manipulating worksheet.

C#

var options = new ExcelExportingOptions();
options.ExcelVersion = ExcelVersion.Excel2013;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.Worksheets[0].Range["A2:A6"].CellStyle.Color = System.Drawing.Color.LightSlateGray;
workBook.Worksheets[0].Range["A2:A6"].CellStyle.Font.Color = ExcelKnownColors.White;
workBook.SaveAs("Sample.xlsx");

Exporting DetailsView

By default, DetailsViewDataGrid will be exported to Excel. You can customize its exporting operation by using ChildExportingEventHandler.

Excluding DetailsViewDataGrid while exporting

You can exclude particular DetailsViewDataGrid while exporting, by using the ChildExportingEventHandler and GridChildExportingEventArgs.Cancel .

C#

var options = new ExcelExportingOptions();
options.ChildExportingEventHandler = ChildExportingHandler;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

private static void ChildExportingHandler(object sender, GridChildExportingEventArgs e)
{
       var recordEntry = e.NodeEntry as RecordEntry;

       if ((recordEntry.Data as OrderInfo).OrderID == 1002)
          e.Cancel = true;
}

Here, DetailsViewDataGrid is not exported for the parent record having OrderID as 1002.

Excluding DetailsViewDataGrid columns from exporting

You can exclude DetailsViewDataGrid columns while exporting, by using ChildExportingEventHandler and GridChildExportingEventArgs.ExcludeColumns.

C#

var options = new ExcelExportingOptions();            
options.ChildExportingEventHandler = ChildExportingHandler;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

private static void ChildExportingHandler(object sender, GridChildExportingEventArgs e)
{            
      e.ExcludeColumns.Add("OrderID");
}

Here, OrderID column is displayed in DetailsViewDataGrid and it is excluded while exporting to excel.

Customizing DetailsViewDataGrid cells

Like parent DataGrid, You can customize the DetailsViewDataGrid cells also by using CellsExportingEventHandler. Based on GridCellExcelExportingEventArgs.GridViewDefinition property, you can identify the particular DetailsViewDataGrid and customize it.

C#

var options = new ExcelExportingOptions();
options.CellsExportingEventHandler = CellExportingHandler;
var excelEngine = dataGrid.ExportToExcel(dataGrid.View, options);
var workBook = excelEngine.Excel.Workbooks[0];
workBook.SaveAs("Sample.xlsx");

private static void CellExportingHandler(object sender, GridCellExcelExportingEventArgs e)
{

    if (e.GridViewDefinition == null || e.GridViewDefinition.RelationalColumn != "ProductDetails")
        return;

    if (e.ColumnName == "OrderID")
    {
        e.Range.CellStyle.Font.Size = 12;
        e.Range.CellStyle.Font.Color = ExcelKnownColors.Blue;
        e.Range.CellStyle.Font.FontName = "Segoe UI";
    }
}

Performance

Using ExcelExportingOptions.CellsExportingEventHandler and changing settings for each cell will consume more memory and time consumption. So, avoid using CellsExportingEventHandler and instead of you can do the required settings in the exported sheet.

Formatting column without using CellsExportingEventHandler

You can perform cell level customization such as row-level styling, formatting particular column in the exported worksheet.

In the below code snippet, NumberFormat for Unit Price column is changed in the exported sheet after exporting without using CellsExportingEventHandler.
