Hi,

How can i check whether "Group by" is enabled/activated for any column on grid corntol.

 

Thanks & Regards

 

 

Here is the code snippet demonstrating how to check whether report grid is grouped:

CExtReportGridWnd * pRGW = . . .
CExtReportGridSortOrder & rgso = pRGW->ReportSortOrderGet();
LONG nCountOfGrouppingColumns = rgso.ColumnGroupCountGet();
bool bReportGridIsGroupped = ( nCountOfGrouppingColumns > 0L ) ? true : false;

Please note, the CExtReportGridWnd class is derived from the CExtTreeGridWnd class. The CExtReportGridItem* pointers can be used as HTREEITEM tree row handles in invocations of the CExtTreeGridWnd class methods. If the report grid control is NOT grouped, then all the tree rows are leaf rows without children. Only the group rows in the report grid control contain children rows. The group rows are completely re-created during re-grouping. I.e. HTREEITEM handles and CExtReportGridItem* pointers of all the group rows are NOT permanent. The data row handles and CExtReportGridItem* pointers are permanent and your app can keep them for using in particular methods.
