How can I make my DataGrid support a single select mode, and not the default multiselect mode

One way to do this is to derive a DataGrid, override its OnMouseDown and OnMouseMove methods. In the OnMouseDown, handle selecting and unselecting in your code without calling the base class if the click is on the header. In the OnMouseMove, don’t call the baseclass to avoid dragging selections. Below is a code snippet for a sample derived DataGrid. You can download a full project (C#, VB).
