Hi,
I have a several questions:
1) When i want to remove all rows from my report grid derived from CExtReportGridWnd class, program causes an exception. I use Prof-UIS V2.54
Call stack:
> mfc71d.dll!CWnd::put_accName(tagVARIANT varChild={...}, wchar_t * szName=0x00000001) Line 3862 + 0x1c C++

ProfUIS254md.dll!CExtGridBaseWnd::RowRemoveAll(bool bRedraw=true) Line 453 C++
How can I solve this trouble?
2) My grid control has checkboxes inside. How can I catch events like "check" and "uncheck" in my class derived from CExtReportGridWnd ? I have tried to reload
virtual void OnGridCellSetCheck();
virtual void OnGridCellInputComplete();
virtual bool OnGridCellButtonPressed();
but had no results.

The CExtGridWnd::RowRemove() and CExtGridWnd::RowRemoveAll() methods should not be used with the CExtReportGridWnd class. If you want to remove all the report grid items (rows), please use the following code: CExtReportGridWnd * pReportGrid = . . .
LONG nColCount = pReportGrid->ColumnCountGet();
LONG nRowCount = pReportGrid->RowCountGet();
if( nRowCount == 0 || nColCount == 0 )
return;
pReportGrid->SelectionUnset( false, false );
pReportGrid->SelectionInsertAt( 0, CRect( 0, 0, nColCount - 1, nRowCount - 1 ), false );
pReportGrid->ReportItemUnRegisterSelection();You can remove a particular report grid item with the code below: CExtReportGridWnd * pReportGrid = . . .
CExtReportGridItem * pRGI = . . .
VERIFY( pReportGrid->ReportItemUnRegister( pRGI ) );
