Prevent Grouping of Specific Pivot Item

15 Jul 20215 minutes to read

The WPF Pivot Grid control allows preventing the drag and drop of certain pivot items in the pivot schema designer or grouping bar.

AllowRunTimeGroupByField

You can prevent the grouping (i.e., drag and drop) for specific pivot item using the AllowRunTimeGroupByField property. It can be defined both in XAML and code-behind.

ShowDisabledGroupBackground

You can provide enabled or disabled background color for corresponding grouping bar item that prevents grouping using the ShowDisabledGroupBackground property of the pivot item. It can be defined both in XAML and code-behind.

If setting both the properties through XAML, refer to the following code sample.

XAML

<Grid>
        <syncfusion:PivotGridControl HorizontalAlignment="Left" Name="pivotGrid" VerticalAlignment="Top" ShowDisabledGroupBackground="True" ItemSource="{Binding   Source={StaticResource data}}">
            <syncfusion:PivotGridControl.PivotRows>
                <syncfusion:PivotItem FieldHeader="Product" FieldMappingName="Product" TotalHeader="Total" AllowRunTimeGroupByField="False" />
                <syncfusion:PivotItem FieldHeader="Date" FieldMappingName="Date" TotalHeader="Total" />
            </syncfusion:PivotGridControl.PivotRows>
            <syncfusion:PivotGridControl.PivotColumns>
                <syncfusion:PivotItem FieldHeader="Country" FieldMappingName="Country" TotalHeader="Total" AllowRunTimeGroupByField="False" />
                <syncfusion:PivotItem FieldHeader="State" FieldMappingName="State" TotalHeader="Total" />
            </syncfusion:PivotGridControl.PivotColumns>
            <syncfusion:PivotGridControl.PivotCalculations>
                <syncfusion:PivotComputationInfo CalculationName="Total" FieldName="Amount" Format="C" SummaryType="DoubleTotalSum" AllowRunTimeGroupByField="False" />
                <syncfusion:PivotComputationInfo CalculationName="Total" FieldName="Quantity" SummaryType="Count" />
            </syncfusion:PivotGridControl.PivotCalculations>
        </syncfusion:PivotGridControl>
    </Grid>

If setting both the properties through code-behind, refer to the following code sample.

C#

public partial class MainWindow: Window {
    public MainWindow() {
        InitializeComponent();
        pivotGrid.ItemSource = ProductSales.GetSalesData();
        PivotItem m_PivotItem = new PivotItem() {
            FieldHeader = "Product", FieldMappingName = "Product", TotalHeader = "Total", AllowRunTimeGroupByField = false
        };
        PivotItem m_PivotItem1 = new PivotItem() {
            FieldHeader = "Date", FieldMappingName = "Date", TotalHeader = "Total"
        };
        PivotItem n_PivotItem = new PivotItem() {
            FieldHeader = "Country", FieldMappingName = "Country", TotalHeader = "Total", AllowRunTimeGroupByField = false
        };
        PivotItem n_PivotItem1 = new PivotItem() {
            FieldHeader = "State", FieldMappingName = "State", TotalHeader = "Total"
        };
        // Adding PivotItem to PivotRows
        pivotGrid.PivotRows.Add(m_PivotItem);
        pivotGrid.PivotRows.Add(m_PivotItem1);
        // Adding PivotItem to PivotColumns
        pivotGrid.PivotColumns.Add(n_PivotItem);
        pivotGrid.PivotColumns.Add(n_PivotItem1);
        PivotComputationInfo m_PivotComputationInfo = new PivotComputationInfo() {
            CalculationName = "Amount", FieldName = "Amount", Format = "C", SummaryType = SummaryType.DoubleTotalSum, AllowRunTimeGroupByField = false;
        };
        PivotComputationInfo m_PivotComputationInfo1 = new PivotComputationInfo() {
            CalculationName = "Quantity", FieldName = "Quantity", SummaryType = SummaryType.Count
        };
        pivotGrid.PivotCalculations.Add(m_PivotComputationInfo);
        pivotGrid.PivotCalculations.Add(m_PivotComputationInfo1);
        // Enabling Disabled Background for Grouping disabled items.
        pivotGrid.ShowDisabledGroupBackground = true;

    }
}
