How-To Select a Row in the DataGrid When the Mouse is Over it

Introduction
If you want to select a row in the DataGrid when the user point the mouse on it (without clicking!!!), Then you will need to do some coding.
The DataGrid has a HitTest method to help us get the cell that the mouse is pointing at. We can use the Select and Unselect methods.

Code
----------------------------------------------
Create a MouseMove event handler to the DataGrid and place this code:

private int _prevRow = -1;
private void dataGrid1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
{
   DataGrid.HitTestInfo info = dataGrid1.HitTest(e.X, e.Y);
   if (info.Type == DataGrid.HitTestType.Cell)
   {
      if (_prevRow != info.Row)
      {
         this.BindingContext[dataGrid1].EndCurrentEdit();
         if (_prevRow != -1)
         dataGrid1.UnSelect(_prevRow);          dataGrid1.Select(info.Row);
         _prevRow = info.Row;
      }
   }
   else
   {
      if (_prevRow != -1)
      {
         dataGrid1.UnSelect(_prevRow);
         _prevRow = -1;
      }
   }
}
