Hello,

I've been using CXTPReportControl (v9.60) for quite a while now, and I think the functionality is really solid.

I am having a problem, though with memory usage. When I add ten to twenty thousand records to the report (which has 9 colums), memory utilization really shoots up. I need the grouping capabilities of the control, so I can't use the "virtual mode" - any general tips on getting memory usage down?

Thanks,

- MR

Is it possible to redraw a specific row of a CXTPReportControl without calling Populate() on the entire control?

For redraw use

RedrawControl instead Populate.

call Populate only if records changed.

Hi Mark,

Regarding memory usage: when you have 9 columns, you see that each corresponding record item contains its own information. I suppose that the biggest part of used memory is spent to storing some string items values. If these values are identical, or they could be calculated somehow at runtime, you can create a kind of specific RecordItem-derived class, which will not store the data (strings or anything) inside itself, but will have some static storage, or calculated at runtime in overridden GetCaption() method.

There could be something like the following:


class CDynamicRecordItemText : public CXTPReportRecordItem

{

public:

     CDynamicRecordItemText();

     virtual CString GetCaption(CXTPReportColumn* pColumn) {

            // calculate caption

            return strCalculatedCaption;

     }

     virtual CString GetGroupCaption(CXTPReportColumn* pColumn) {

            // calculate group caption

            return strCalculatedGroupCaption;

     }

};



class CCommonRecordItemText : public CXTPReportRecordItem

{

public:

     CCommonRecordItemText();

     virtual CString GetCaption(CXTPReportColumn* pColumn) {

            return ms_strText;

     }

private:

     static CString ms_strText;

};
