State Persistence in WPF Pivot Grid

27 Feb 20255 minutes to read

The pivot grid allows you to maintain the collapsed or expanded state when the corresponding schema items are changed. This can be achieved using the StatePersistence property of the pivot grid control.

For XAML, refer to the following code sample.

XAML

<Grid>
        <syncfusion:PivotGridControl HorizontalAlignment="Left" Name="pivotGrid" VerticalAlignment="Top" StatePersistenceEnabled="True" ItemSource="{Binding   Source={StaticResource data}}">

            <syncfusion:PivotGridControl.PivotRows>
                <syncfusion:PivotItem FieldHeader="Product" FieldMappingName="Product" TotalHeader="Total" />
                <syncfusion:PivotItem FieldHeader="Date" FieldMappingName="Date" TotalHeader="Total" />
            </syncfusion:PivotGridControl.PivotRows>
            <syncfusion:PivotGridControl.PivotColumns>
                <syncfusion:PivotItem FieldHeader="Country" FieldMappingName="Country" TotalHeader="Total" />
                <syncfusion:PivotItem FieldHeader="State" FieldMappingName="State" TotalHeader="Total" />
            </syncfusion:PivotGridControl.PivotColumns>
            <syncfusion:PivotGridControl.PivotCalculations>
                <syncfusion:PivotComputationInfo CalculationName="Total" FieldName="Amount" Format="C" SummaryType="DoubleTotalSum" />
                <syncfusion:PivotComputationInfo CalculationName="Total" FieldName="Quantity" SummaryType="Count" />
            </syncfusion:PivotGridControl.PivotCalculations>

        </syncfusion:PivotGridControl>
    </Grid>

For code-behind, refer to the following code sample.

C#

public partial class MainWindow: Window {
    PivotGridControl pivotGrid = new PivotGridControl();
    public MainWindow() {
        InitializeComponent();
        grid1.Children.Add(pivotGrid);
        pivotGrid.ItemSource = ProductSales.GetSalesData();
        PivotItem m_PivotItem = new PivotItem() {
            FieldHeader = "Product", FieldMappingName = "Product", TotalHeader = "Total"
        };
        PivotItem m_PivotItem1 = new PivotItem() {
            FieldHeader = "Date", FieldMappingName = "Date", TotalHeader = "Total"
        };
        PivotItem n_PivotItem = new PivotItem() {
            FieldHeader = "Country", FieldMappingName = "Country", TotalHeader = "Total"
        };
        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
        };
        PivotComputationInfo m_PivotComputationInfo1 = new PivotComputationInfo() {
            CalculationName = "Quantity", FieldName = "Quantity", SummaryType = SummaryType.Count
        };
        pivotGrid.PivotCalculations.Add(m_PivotComputationInfo);
        pivotGrid.PivotCalculations.Add(m_PivotComputationInfo1);

        pivotGrid.StatePersistenceEnabled = true;
    }
}
