Strange behavior when trying to SetCaption

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello,

I'm observing strange behavior - I populate my records as normal, then one record is changed and I use:

pRecord->GetItem(9)->SetCaption(strCaption);

to update the displayed text, which does that in all cases, except:

If GetItem(9) was not an empty string when Populate() was called and I then try to set it with an empty string, it reverts back to the original non-empty value. So, let's say it was "abc" initially, then I call SetCaption(""), it displays "abc".

Also, I can change it to "def", it displays "def", then I set it to "" and it displays "abc" again.

Weird  Am I doing something wrong or is there  a bug in the control?

Thanks,

Dennis

	Check your item type - (CXTPReportRecordItem or CXTPReportRecordItemText or other derived types) Compare 2 cases on initialization 1 - AddItem(new CXTPReportRecordItemText("ABC")); // this case will not allow empty string to set as caption because "ABC" will be default value. 2 - AddItem(new CXTPReportRecordItemText())->SetCaption("ABC"); //this case will allow empty string to set as caption as default value now - empty string btw - you can use more simple function: GetReportCtrl().SetCellText(Row#, Col#, Text); CXTPReportRecordItemText::CXTPReportRecordItemText(LPCTSTR szText) : CXTPReportRecordItem(), m_strText(szText) { } CString CXTPReportRecordItemText::GetCaption(CXTPReportColumn* /pColumn/) { if (!m_strCaption.IsEmpty()) return m_strCaption; if (m_strFormatString == _T("%s")) return m_strText; CString strCaption; strCaption.Format(m_strFormatString, (LPCTSTR)m_strText); return strCaption; } void CXTPReportRecordItemText::OnEditChanged(XTP_REPORTRECORDITEM_ARGS* pItemArgs, LPCTSTR szText) { SetValue(szText); CXTPReportRecordItem::OnEditChanged(pItemArgs, szText); } void CXTPReportRecordItemText::DoPropExchange(CXTPPropExchange* pPX) { CXTPReportRecordItem::DoPropExchange(pPX); PX_String(pPX, _T("Text"), m_strText, _T("")); }

	SetValue (with casting to *text) seems to do the trick! Thanks, Dennis

	CXTPReportRecordItemText allow to use in-place-edit control with validation and user choice to escape in any point including one - select content - (Ctrl+A) - cut it (Ctrl+C) - escape - and Core should restore old value!
