How to Add Event Triggers for DetailsViewDataGrid in WPF?
In WPF DataGrid (SfDataGrid), EventTriggers added for the DetailsView DataGrid which is defined within the SfDataGrid.DetailsViewDefinition in XAML will not work, as it is not the same UI element which is displayed as the child DataGrid. However, it is possible to add EventTrigger for the DetailsView DataGrid in code behind by using DetailsViewLoading event.
C#
private void OnDataGrid_DetailsViewLoading(object sender, DetailsViewLoadingAndUnloadingEventArgs e)
{
System.Windows.Interactivity.EventTrigger trigger = new System.Windows.Interactivity.EventTrigger();
trigger.EventName = "CellTapped";
InvokeCommandAction action = new InvokeCommandAction();
action.Command = (this.DataContext as ViewModel).CellTappedCommand;
trigger.Actions.Add(action);
trigger.Attach(e.DetailsViewDataGrid);
}
Take a moment to peruse the documentation, where you can find about Master-Details view in SfDataGrid, with code examples.
You can download the example from GitHub
