I have a master/detail grid that I want to be able to delete from from the detail table, but not the master table.  I set IsDeleteCommandEnabled to true on the DetailConfiguration, and to false on the master grid.  However, the delete key doesn't work.  When I set IsDeleteCommandEnabled on the master grid, it starts working, but then users can delete rows from the master as well (which I don't want).

How can I get this to work?

Hi Nathan,

In order to delete DataItems from the Datagrid you should set the IsDeleteCommandEnabled property on the DataGrid to True. However, to delete only Details' items you should catch the DeletingSelectedItems event in code behind and cancel deletion if the CurrentContext is a master one(ParentDataGridContext will be null as a master item has no parent).

For example your event handler could be something like:


private void DataGridControl_DeletingSelectedItems(object sender, Xceed.Wpf.DataGrid.CancelRoutedEventArgs e)
{
           if (OrdersDataGrid.CurrentContext.ParentDataGridContext == null)
           e.Cancel = true;
}


Best regards,
