PivotGridField.CellTemplate Property

Gets or sets a template used to display cells that correspond to the current field. This is a dependency property.

Namespace: DevExpress.Xpf.PivotGrid

Assembly: DevExpress.Xpf.PivotGrid.v23.2.dll

NuGet Package: DevExpress.Wpf.PivotGrid

Declaration

C#

public DataTemplate CellTemplate { get; set; }

VB.NET

Public Property CellTemplate As DataTemplate

Property Value

Type	Description
DataTemplate	A DataTemplate object used to display cells that correspond to the current field.

Remarks

If the CellTemplate is not specified, the cells are displayed via the PivotGridControl.FieldCellTemplate template (or the PivotGridControl.FieldCellKpiTemplate if this field displays KPI graphics). The PivotGridField.ActualCellTemplate property allows you to obtain which template is currently used.

You can implement custom logic to choose the required template using the PivotGridField.CellTemplateSelector property.

Example

The PivotGrid control does not support the data editing functionality out of the box because it displays aggregated data. This example demonstrates how to implement a custom CellTemplate with the in-place editing functionality.

This example implements the base editing features. It does not allow going to the next cell by pressing the tab or arrow keys.

The PivotGridEditHelper class implements the in-place cell editor. When editing is finished, the editor calls the pvotGridControl1_OnCellEdit method. This method retrieves the underlying data for the edited cell and adjusts them so that their sum equals the new value entered in the cell.
