AncestorType for a button inside a column of a Master-Details datagrid


I have a button that launch a specifi command inside a column of my datagrid, in the details part of a master-details.

The button command is define as also :

Command="{Binding DataContext.SupprimerVilleCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type syncfusion:SfDataGrid}}}"

But the command is never launched, and an error is displayed in Visual Studio output window :

System.Windows.Data Error: 40 : BindingExpression path error: 'SupprimerDepartementCommand' property not found on 'object' ''EntityCollection`1' (HashCode=39200294)'. BindingExpression:Path=DataContext.SupprimerDepartementCommand; DataItem='DetailsViewDataGrid' (Name=''); target element is 'Button' (Name=''); target property is 'Command' (type 'ICommand')

What is the correct AncestorType to specify in this case ?

Thanks for your help.

Thank you for using Syncfusion Products.

You can achieve your requirement to launch the button command inside the details view datagrid column by setting the AncestorLevel based on the details grid level like the below code example,
Code Example:

<syncfusion:GridTemplateColumn MappingName="CustomerID" syncfusion:FocusManagerHelper.WantsKeyInput="True">



             <Button  Content="Click" syncfusion:FocusManagerHelper.FocusedElement="True"

        Command="{Binding Path=DataContext.ToggleExecuteCommand,RelativeSource={RelativeSource AncestorLevel=2, AncestorType=syncfusion:SfDataGrid}}" />



We have prepared a sample based on this and you can download the sample from the below location,
