Are you calling the Static HitTestInfo? Try this C# code:

private void dataGrid1_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e) 
{ 
     System.Drawing.Point pt = new Point(e.X, e.Y); 
     DataGrid.HitTestInfo hti = dataGrid1.HitTest(pt); 
     if(hti.Type == DataGrid.HitTestType.Cell) 
     { 
          dataGrid1.CurrentCell = new DataGridCell(hti.Row, hti.Column); 
          dataGrid1.Select(hti.Row); 
     } 
}

>I'm using C#, so I tried to convert it. However, I must be missing something, because I'm not able to access things like HITTESTINFO. I even tried a code sample from MSDN that was written for .NET, but the code that I paste in doesn't even run. (Even typing 'System.Windows.Forms.DataGrid.HitTestInfo myhit results in an error).
