Hi-

I know that you can wrap text using DT_WORDBREAK, but is it possible to always show some of a rows column data underneath other column data?

For example:

---------------------------------------------

ROW1 Date1 Time1

Subject1 Attachment1

---------------------------------------------

ROW2 Date2 Time2

Subject2 Attachment2

---------------------------------------------

ROW3 Date3 Time3

Subject3 Attachment3

---------------------------------------------

... etc? It doesn't look like the control handles this situation out of the box, but what exactly needs to be customized to accomplish this effect?

Thanks,

-Matt

You'll need a custom paint manager, and custom items in your record.

Paint manager is so you can do something like this:

class CMyReportPaintManager : public CXTPReportPaintManager
{
public:
   CMyReportPaintManager() {}
   ~CMyReportPaintManager() {}
 
   virtual int GetRowHeight(CDC* pDC, CXTPReportRow* pRow)
   {
      if (HasMultirowItems(pRow))
      {
         ...Calculate the height of the tallest item in the record...;
         return nCalculatedHeight
      }
      return CXTPReportPaintManager::GetRowHeight(pDC, pRow);
   }
   virtual int GetRowHeight(CDC* pDC, CXTPReportRow* pRow, int nTotalWidth)
   {
      if (HasMultirowItems(pRow))
      {
         ...Calculate the height of the tallest item in the record...;
         return nCalculatedHeight
      }
      return CXTPReportPaintManager::GetRowHeight(pDC, pRow, nTotalWidth);
   }
};

The custom items will draw themselves

class CMyRecordItem : public CXTPReportRecordItemText
{
   DECLARE_DYNAMIC(CSidebarRecordItem);
public:
   CMyRecordItem(LPCTSTR sz) : CXTPReportRecordItemText(sz) {}
   ~CMyRecordItem() {}
 
   virtual int Draw(XTP_REPORTRECORDITEM_DRAWARGS* pDrawArgs)
   {
      // See the draw code in XTPReportRecordItem.cpp line 295
      // this code will provide a base for the rest of this
   }
};

That's a general direction for you anyway. There might be a better angle on this (for example, you might get the measuring to happen automatically just by overriding some stuff in the item) but that should get you started.
