Public Property CellTemplateSelector As DataTemplateSelector
| Type | Description |
|---|---|
| DataTemplateSelector |
A DataTemplateSelector descendant that chooses a template based on custom logic.
|
The ColumnBase.CellTemplate property specifies the template that defines the contents of a column cell. If you have more than one template to render cells, you can implement custom logic to choose the required template. To do this, derive from the DataTemplateSelector class and implement the SelectTemplate method that returns a template for each condition.
If you specify both the ColumnBase.CellTemplate and CellTemplateSelector , the CellTemplateSelector defines the cell template. If the template selector returns null , the template specified by the ColumnBase.CellTemplate property is used.
This sample illustrates how to use the CellTemplateSelector to change a cell template based on a condition:

To implement this task, do the following:
Implement custom DataTemplates. Editors declared in these templates should follow our recommendations from this help topic: ColumnBase.CellTemplate:
Create a custom DataTemplateSelector descendant. This descendant should return templates according to your scenario requirements.
Cell elements contain EditGridCellData objects in their DataContext.
Use the following binding paths to access cell values, columns, and ViewModel properties:
Value - access the current cell value;Column - access the current column;RowData.Row.[YourPropertyName] - access a property of an object from the ItemsSource collection;Data.[FieldName] - access column values in Server Mode or if you use the RealTimeSource, access unbound column values;View.DataContext.[YourPropertyName] - access a property in a grid’s ViewModel.View Example: Build Binding Paths in WPF Data Grid Cells
