Examples

The following example tests whether the user is clicking an area of the grid that is not valid.

private:
   void dataGrid1_MouseDown( Object^ /*sender*/,
     System::Windows::Forms::MouseEventArgs^ e )
   {
      if ( dataGrid1->HitTest( e->X, e->Y )->Equals(
         DataGrid::HitTestInfo::Nowhere ) )
      {
         Console::WriteLine( "Nowhere" );
      }
   }

private void dataGrid1_MouseDown
(object sender, System.Windows.Forms.MouseEventArgs e)
{
   if(dataGrid1.HitTest(e.X,e.Y).Equals (DataGrid.HitTestInfo.Nowhere)) 
   {
      Console.WriteLine("Nowhere");
   }
}

Private Sub dataGrid1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)
    If dataGrid1.HitTest(e.X, e.Y).Equals(DataGrid.HitTestInfo.Nowhere) Then
        Console.WriteLine("Nowhere")
    End If
End Sub

Remarks

Other parts of the System.Windows.Forms.DataGrid, such as the Caption, can return useful information. If the part of the grid has no function (such as the gray area behind a sparsely populated grid table), the Nowhere field is returned.
