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 ------------- // W7 64 Ultimate SP1 // VS 2008 // CodeJock 16.2.3 (MFC) |

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(""));} ------------- Mark Doubson, Ph.D. |

SetValue (with casting to *text) seems to do the trick! Thanks, Dennis ------------- // W7 64 Ultimate SP1 // VS 2008 // CodeJock 16.2.3 (MFC) |

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! ------------- Mark Doubson, Ph.D. |
