We are testing next release now but without recent changes.

On updating ReportControl the text are taken from DB, so I can suppose that you just don't save changes in DB. See methods CVirtualRecord::UpdateRecordField and CVirtualRecord::GetItemMetrics in sample VirtualList\VirtualListView.cpp My changes in Header section available also after restarting sample.

Hi;

Now I have another problem:
I have no records in the body section.
I'm editing an item in the (only single) header row. That's ok, but when I click into the header item a second time, the text disappears. Moving the focus out of the item without typing, I see the initially entered text again.
If the control has records in the body section, the item and edit control behave as expected.
Strange!
You can reproduce it with the above mentioned sample.

Hello Martin,

I have found what is the reason. Problem was in method CXTPReportControl::EditItem().

It resets pItemArgs->pRow but gets row always from body section. So fixed code is below:

void CXTPReportControl::EditItem(XTP_REPORTRECORDITEM_ARGS *pItemArgs){
    CXTPReportRecordItem *pItem = pItemArgs ? pItemArgs->pItem : NULL;

    if (NULL == m_pActiveItem && NULL == pItem)
    {
        // Nothing do to
        return;
    }

    if (m_pActiveItem != NULL)
    {
        m_pActiveItem->OnCancelEdit(this, TRUE);
        m_pActiveItem = NULL;

        if (!m_bFocusSubItems)
            SetFocusedColumn(NULL);
    }
    CMDTARGET_RELEASE(m_ptrVirtualEditingRow);

    if (pItem && pItemArgs && pItemArgs->pRow)
    {
        if (!HasFocus())
            SetFocus();

        if (!IsVirtualMode())
        {
            AdjustScrollBars();
            RedrawControl();
            UpdateWindow();
        }

        if (IsVirtualMode())
        {
            int nRowIndex = pItemArgs->pRow->GetIndex();
            CXTPReportSection* pSection = pItemArgs->pRow->GetSection();
            ASSERT(pSection != NULL);

            //EnsureVisible(pItemArgs->pRow);

            RedrawControl();
            UpdateWindow();
            pItemArgs->pRow = NULL; // RedrawControl delete and re-create new screen rows

            BOOL bMapped = FALSE;

            if (pSection)
            {
                CXTPReportScreenRows *pScreenRows = pSection->GetRows()->GetScreenRows();
                for (int i = 0; i GetSize(); i++)
                {
                    CXTPReportRow* pRow = pScreenRows->GetAt(i);
                    if (pRow->GetIndex() == nRowIndex)
                    {
                        pItemArgs->pRow = pRow;
                        bMapped = TRUE;

                        ASSERT(m_ptrVirtualEditingRow == NULL);

                        m_ptrVirtualEditingRow = pRow;
                        CMDTARGET_ADDREF(m_ptrVirtualEditingRow);
                        break;
                    }
                }
            }
            ASSERT(bMapped);
            if (!bMapped)
                return;
        }
        else if (GetFocusedRow() != pItemArgs->pRow)
        {
            BOOL bControlKey = (::GetKeyState(VK_CONTROL) < 0) || m_bMultiSelectionMode;
            SetFocusedRow(pItemArgs->pRow, bControlKey);
            UpdateWindow();
        }
    ....

Also you should use separated CVirtualRecord for header or footer sections because callback method for updating CVirtualRecord::UpdateRecordField() don't recognize sections. It used only row and column positions to identify records. Also for separates data sets. However maybe this will useful for you as is.

[HOWTO] Edit in header rows in virtual mode : Hi;I try to edit header row items...

Hi;

I try to edit header row items when I use a virtual report control in Toolkit 18.0.1.
As a starting point I use the CJ "Virtual List Sample".

I modified the code by adding those lines to the CVirtualListView::OnCreate function:

wndReport.GetHeaderRecords()->Add(new CVirtualRecord(pSet));
wndReport.ShowHeaderRows(TRUE);
wndReport.HeaderRowsAllowAccess(TRUE);
wndReport.HeaderRowsEnableSelection(TRUE);
wndReport.HeaderRowsAllowEdit(TRUE);

In body section the edit control appears, but not in the header section.

What's wrong?

TIA
