I have two DataGrids.

An instance of  A contains a BindingList of B and each B has a BindingList of C.

My first grid displays all B instances. I want the second grid to display the instances of C contained within the selected B.

I have the first grid working fine. How do I update the second grid (ie display the instances of C related to the selected B in the first grid) when the user switches row on the first grid? I assumed there would be an event to catch on the grid - but I can't work out which to catch. (Or is there a better way?)

You have to wire up a SelectedItemChanged event, which listens to the SelectedItemProperty of the grid

DependencyPropertyDescriptor SelectedItemChangedDescriptor = DependencyPropertyDescriptor.FromProperty(DataGridControl.SelectedItemProperty, typeof(DataGridControl));
SelectedItemChangedDescriptor.AddValueChanged(this, new EventHandler(OnSelectedItemChanged));

private void OnSelectedItemChanged(object sender, EventArgs e)
{

//Do processing here

}
 

Cheerios,

Serene
