• GX_DNDSTYLES - supply data in internal styles format
  
  
• GX_DNDCOMPOSE - when copying internal styles, compose the full style of the cell and do not copy only the cell-specific attributes.

Return Value

TRUE if OLE Drag&Drop functionality could be initialized; FALSE if initialization failed.

Remarks

Call this function to enable OLE Drag&Drop functionality in the grid for dragging cells to other OLE Drag&Drop-enabled applications.

Example:

void CMyGridView::OnInitialUpdate()
{
#if _MFC_VER >= 0x0400
   EnableOleDropTarget(GX_DNDEGDESCROLL | GX_DNDAUTOSCROLL | GX_DNDTEXT | GX_DNDSTYLES);
   EnableOleDataSource();
#endif

   CGXGridView::OnInitialUpdate();
}

Make sure that OLE Drag&Drop support has been linked into the grid library. See the section "Reducing the size of your application" in the user's guide how to remove or include Ole Drag&Drop support from the grid library using the Build Wizard.
