Working with Template Markers

18 Jan 202124 minutes to read

A template marker is a special marker symbol created in an Excel template that appends multiple records from a data source into a worksheet. This marker automatically maps the column name in the data source and names of the marker fields in the template Excel document and fills the data (text or image). Essential XlsIO allows you to bind the template markers to data from various sources, such as

  • DataTable
  • Collection objects
  • Nested collection objects
  • Arrays

Template marker Syntax

Each marker starts with a prefix character (by default it is “%” character). The marker is followed by the variable name and properties which are delimited by a character (by default it is semicolon “;”.)

%<MarkerVariable>.<Property>

For example: %Customers.CompanyName

Where, “Customers” is marker variable name and CompanyName is the property name

You can change the marker prefix and delimiter characters by the MarkerPrefix and ArgumentSeparator properties of the ITemplateMarkersProcessor instance respectively.

Arguments

You can specify the following arguments with the marker to customize the worksheet.

Horizontal-This argument specifies the horizontal direction of the data filling for variables.

Syntax: %<MarkerVariable>.<Property>;horizontal

Vertical-This argument specifies the vertical direction of the data filling for variables. By default, data will be filled in vertical direction

Syntax: %<MarkerVariable>.<Property>;vertical

insert-This argument inserts new row or column, depending on the direction argument for each new cell. Note that by default, the rows will not be inserted.

Syntax: %<MarkerVariable>.<Property>;insert

insert:copystyles-This argument copies styles from the above row or left column.

Syntax: %<MarkerVariable>.<Property>;insert:copystyles

jump:[cell reference in R1C1 notation]-This argument binds the data to the cell at the specified reference. Cell reference addresses can be relative or absolute.

Syntax: %<MarkerVariable>.<Property>;jump:R2C2

copyrange:[top-left cell reference in R1C1]:[bottom-right cell reference in R1C1]-Copies the specified cells after each cell import.

Syntax: %<MarkerVariable>.<Property>;copyrange:R2C2:R4C4

default-This argument adds the property value once per object for the corresponding records in the column while importing nested collection objects.

Syntax: %<MarkerVariable>.<Property>default

merge-This argument merges the cells in the column for each object set while importing nested collection objects.

Syntax: %<MarkerVariable>.<Property>merge

repeat-This argument repeats the property value for the corresponding records in the column while importing nested collection objects.

Syntax: %<MarkerVariable>.<Property>repeat

collapsegroup-This argument groups the cells in the column for each object set and collapse the data while importing nested collection objects.

Syntax: %<MarkerVariable>.<Property>collapsegroup

expandgroup-This argument groups the cells in the column for each object set and expand the data while importing nested collection objects.

Syntax: %<MarkerVariable>.<Property>expandgroup

Bind from Array

An array of data can be binded to the marker in the template document.

Syntax: %VariableArray

The following screenshot represents the input template which has a template marker.

Bind from Array Example

Following code example illustrates how to bind the data from an array to a marker.

using (ExcelEngine excelEngine = new ExcelEngine())
{
  ExcelEngine excelEngine = new ExcelEngine();
  IWorkbook workbook = excelEngine.Excel.Workbooks.Open("Sample.xlsx");
  IWorksheet worksheet = workbook.Worksheets[0];

  //Create Template Marker Processor
  ITemplateMarkersProcessor marker = workbook.CreateTemplateMarkersProcessor();

  //Insert Array Horizontally
  string[] names = new string[] { "Mickey", "Donald", "Tom", "Jerry" };
  string[] descriptions = new string[] { "Mouse", "Duck", "Cat", "Mouse" };
  
  //Add collections to the marker variables where the name should match with input template
  marker.AddVariable("Names", names);
  marker.AddVariable("Descriptions", descriptions);

  //Process the markers in the template
  marker.ApplyMarkers();

  workbook.Version = ExcelVersion.Excel2013;
  workbook.SaveAs("TemplateMarker.xlsx");
}

  //Add collections to the marker variables where the name should match with input template
  marker.AddVariable("Names", names);
  marker.AddVariable("Descriptions", descriptions);

You can also add or insert template markers using XlsIO APIs as follows.

Bind from DataTable

Syntax:

%<DataSource>.<FieldName>

For example: %Products.ProductName

Where, “Products” is a data source which can be data tables, datasets, data readers and data views and ProductName is the field name or column name

By default, DataTable values will be filled in the worksheet as a string format. You can detect data type and number format of DataTable values by using VariableTypeAction enumerator. To know more about the VariableTypeAction enumerator, please refer VariableTypeAction in API section.

The following screenshot represents the input template which has a template marker.

Bind from DataTable Example

The following code snippet illustrates how to detect data type and apply number format with template marker.

using(ExcelEngine excelEngine = new ExcelEngine())
{
  IWorkbook workbook = excelEngine.Excel.Workbooks.Open("TemplateMarker.xlsx");

  //Create Template Marker Processor
  ITemplateMarkersProcessor marker = workbook.CreateTemplateMarkersProcessor();

  DataTable reports = new DataTable();

  reports.Columns.Add("FromDate", typeof(DateTime));
  reports.Columns.Add("ToDate", typeof(DateTime));

  reports.Rows.Add("Jim Halpert", new DateTime(2014, 09, 11), new DateTime(2014, 09, 15));
  reports.Rows.Add("Karen Fillippelli", new DateTime(2014, 09, 15), new DateTime(2014, 09, 20));

  //Add collection to the marker variables where the name should match with input template
  //Detects number format in DateTable values
  marker.AddVariable("Reports", reports,VariableTypeAction.DetectNumberFormat);

  marker.ApplyMarkers();

Bind from DataTable Example

Bind from Collection Objects with images

You can generate reports more appealingly with image support in template markers. The possible image formats are as follows:

  • GIF
  • JPEG
  • PNG
  • BMP
  • TIFF

XlsIO detects the property as image when its type is System.Drawing.Image or byte []. The image can be formatted using the following arguments.

No

 Image arguments

 Description
1

 No argument
Ex: %Reports.Image;

 Image is applied with a default size (50x50 pixels) and position (Top-Left).
2

 fittocell
Ex: %Reports.Image;fittocell

 The image is applied to cell width and height.
3

 size:width,height

Ex:

%Reports.Image;size:60

(or)

%Reports.Image;size:60,60

(or)

%Reports.Image;size:60,auto

(or)

%Reports.Image;size:auto,60

(or)

%Reports.Image;size:auto,auto

 Image is applied to the specified size (width, height).

Height parameter is optional. Value of width is applied when height is not specified.



You can specify either width or height value as "auto" to set ratio value of other size value.

If both width and height value is set as "auto" then the Image is applied to the original size
4

 position:position

Ex:

%Reports.Image;position:middle-center

(or)

%Reports.Image;position:right 

 Image is positioned (top-left, top-center, etc.,) within the cell.

In the following example, a marker is added for merging images. Data source and property name is specified (%Reports.Image;) for image also.

Import collection objects with images Example

Marker added for merging images

NOTE

Image can be used in array, DataTable, and collection objects.

Different positions of the image are maintained internally in the ImageVerticalPosition and ImageHorizontalPosition enumerators. To learn more about this, refer to the ImageVerticalPosition and ImageHorizontalPosition enumerators respectively in API section.

The output of all the image insertion options with input templates are as follows.

Default image input and output

Bind from Nested Collection Objects with import data and group options

You can bind the data from Nested collection objects with import data options and group options.

The import data options are:

  • Default
  • Merge
  • Repeat

The import data group options are:

  • Collapse Group
  • Expand Group

The following code snippet illustrates how to import data from nested collection objects with template marker.

Template marker with conditional formatting

You can create or apply conditional format to the template marker range.

The following screenshot represents the input template, which has a template marker.
