Dears,

How can I hold a specific dialog/window in a ellipsis button in grid control ?

Dear Luis,

To display your dialog when the ellipsis button is clicked, you should use your own grid cell class and override the CExtGridCell::OnButtonPressed() virtual method. Here is a sample:



 
class CMyCell : public CExtGridCellStringDM
{
public:
     // runtime type info that required for grid cells
     DECLARE_DYNCREATE( CMyCell );
     IMPLEMENT_ExtGridCell_Clone(
                        CMyCell, CExtGridCellStringDM );
     // constructor
     CMyCell (
         CExtGridDataProvider * pDataProvider = NULL
         )
         : CExtGridCellStringDM( pDataProvider )
     {
     }
     // handle the cell button clicks
     void OnButtonPressed(
         CExtGridWnd & wndGrid,
         INT nButtonType,
         const RECT & rcCellExtra,
         const RECT & rcCell,
         LONG nVisibleColNo,
         LONG nVisibleRowNo,
         LONG nColNo,
         LONG nRowNo,
         INT nColType,
         INT nRowType
         )
     {
         ASSERT_VALID( this );
         ASSERT_VALID( (&wndGrid) );
         if( nButtonType != __EBTT_ELLIPSIS )
         { // if not an ellipsis button pressed
              CExtGridCellStringDM::
                                               OnButtonPressed(
                               wndGrid,
                               nButtonType,
                              rcCellExtra,
                               rcCell,
                               nVisibleColNo,
                               nVisibleRowNo,
                               nColNo,
                              nRowNo,
                               nColType,
                               nRowType
                               );
              return;
         } // if not an ellipsis button pressed
         // update cell
         wndGrid.InvalidateRect( &rcCellExtra );
         wndGrid.UpdateWindow();
         // display your dialog here:
         CYourDialog dlg( &wndGrid );
         dlg.DoModal();
     }
}; // class CMyCell
 

// runtime type info that is required for grid cells
IMPLEMENT_DYNCREATE( CMyCell, CExtGridCellStringDM );
 

 
 CExtGridCell * pCell =
     m_wndGrid.GridCellGet(
         nColNo, nRowNo, 0, 0,
         RUNTIME_CLASS(CMyCell )
         );
// pCell should point to an object of CMyCell if this
// position previously haven’t had a cell at all
