Hi!

I am trying to add "Ctrl + A" functionality to my XamDataGrid which is supposed to set all Cells to selected. I use a RelayCommand to trigger when "Ctrl + A" is pressed by the user. I also have a behavior which listens to SelectedItemsChanged and gets all selected the cells and sets them in a DependencyProperty I can bind to. I manged to set all Records to selected in code behind, which triggered my behavior event, but the selected cells collection was empty.

So, how do I set the XamDataGrid.SelectedItems.Cells collection programatically so I can get them in the event below?

This is my event in my behavior: 

private void OnSelectedItemsChanged(object sender, SelectedItemsChangedEventArgs e)
{
   XamDataGrid dataGrid = (XamDataGrid) sender;
   SelectedCellCollection selected = dataGrid.SelectedItems.Cells;
   List<object> items = new List<object>();
   foreach (Cell cell in selected)
   {
     items.Add(cell.Value);
   }

    // Set the selected cell items in the depentency property
   SelectedItems = items;
}
