Patience! Oh Patience, that can bear so much!

O, pazienza, pazienza che tanto sostieni! (Dante) Patience! Oh patience that can bear so much! I battled for more than two days in a Prism application to get events in a Blend-type behavior to work. The behavior was supposed to set the headings for a DataGrid when the ItemsSource for the DataGrid was set to a specific DataTable. The DataGrid was set to autogenerate columns. I got some really weird effects, until I finally figured out I had to introduce a 100 millisecond delay after the View that held the DataGrid loaded, before I loaded the DataTable. Suddenly all weirdness was gone! All that was needed was patience for a 100 ms delay after the View loaded! I introduced the delay using the DispatcherTimer. A lesson learnt costing me two days of my life!
Get me coffee and no one gets hurt!

Keep in mind that the View's loaded event fires before it is rendered and becomes visible. There are still UI element activity after the event fired. If the View is a window, I will prefer to use the ContentRendered event, but in Prism the View is usually a UserControl, that does not have a ContentRendered event.
