How to select a row or a cell in WPF DataGrid programmatically?

Question

In WinForm DataGridView, it automatically selects the first row when initialized. It drove me crazy when I tried to turn that feature off. Moving to WPF DataGrid, it seems M

You can do this consistently in the DataGrid.Loaded event. Just obtain the first row and have the row fire the selection event.

void MyGridLoaded(...) {
DataGridRow r = yourGrid.ItemContainergenerator.ContainerFromIndex(0) as DataGridRow;
  if(r != null) {
     r.IsSelected = false;
     r.IsSelected = true;
  }

} 

I'm not sure this is a bug because you may not be guaranteed to have selection events fire from your object until the control is loaded. Don't know.
