ASPxGridView - How to manipulate the control inside DataItemTemplate when a row is selected

This example demonstrates how to manipulate the control inside DataItemTemplate when a row is selected.

1) Define the ASPxSpinEdit editor inside a column's DataItemTemplate and bind the editor with a corresponding column value;
2) Handle the ASPxSpinEdit.Init event and set its unique ASPxSpinEdit.ClientInstanceName property based on the row's VisibleIndex;
3) Handle the client-side ASPxClientGridView.SelectionChanged event and manipulate the ASPxClientSpinEdit.SetEnabled property based on the row selection.
