Examples

The following example prints the clicked part of the grid by calling the HitTest method from within the MouseDown event of a System.Windows.Forms.DataGrid control. This returns a DataGrid.HitTestInfo object.

private:
   void dataGrid1_MouseDown( Object^ /*sender*/,
      System::Windows::Forms::MouseEventArgs^ e )
   {
      String^ newLine = "\n";
      Console::WriteLine( newLine );
      System::Windows::Forms::DataGrid::HitTestInfo^ myHitTest;
      // Use the DataGrid control's HitTest method with the x and y properties.
      myHitTest = dataGrid1->HitTest( e->X, e->Y );
      Console::WriteLine( "Hit {0}", ReturnHitTest( myHitTest->Type ) );
   }

   String^ ReturnHitTest(
      System::Windows::Forms::DataGrid::HitTestType hit )
   {
      // Use this function to return the part of the grid clicked.   
      switch ( hit )
      {
      case(System::Windows::Forms::DataGrid::HitTestType::Cell):
         return "Cell";
