dear support, if i was doing the PrintPreviewMod ervery line was expanded! But what i want to do is printing the actual state of the grid. if i had expand the first row only I want print only the first row expanded and the others collapsed. for further explenations look at these two pictures: Pic1: I only expand the first row: Pic2: the resulting PrintPreview: so the print preview contains more informatins which I would not like to have. Are there any possibilities to control that? best regards Johannes Jahn

Please override the following virtual method in your CExtPPVW < CExtReportGridWnd > -derived class and fill the array of report row pointers which should be printed/previewed: virtual void OnCalcPrintableTreeItemArray(
CArray < HTREEITEM, HTREEITEM & > & arrPrintableItems
);
The CExtReportGridItem* pointers can be used as HTREEITEM tree grid row handles. By default, the CExtPPVW < CExtReportGridWnd > :: OnCalcPrintableTreeItemArray() method computes an array of all the report grid rows including data rows and group rows.
