I've been looking for a way to add a textual grid item that has more than one line of text - e.g. an address or a user's short free format comment.

Any pointers would be appreciated

I've been using the PropertyGrid for a while, and I'm 99% sure there's no way to do this. I suggest submitting a feature request to Codejock.

Thanks, I thought that was the case.

I'm waiting to find out if it is an absolute requirement for my project or not. If it is then I'll look to see if there is a way to subclass and owner draw but it sounds like more effort than its worth.

I have managed to display multiline text, though editing it still lies ahead.

Basically the code uses owner draw variable height and a class especially for the multi line text.

The property grid creation has to specify the style...


if ( m_wndPropertyGrid.Create( rc, this, IDC_PROPERTY_GRID, LBS_OWNERDRAWVARIABLE ) )

Then adding a property uses a new class


CXTPPropertyGridItem* pSettings = m_wndPropertyGrid.AddCategory(_T("Example"));
strTesting = "Hello\nWorld";
(void)pSettings->AddChildItem(new CMultilineTextGridItem(_T("TESTING"), strTesting, &strTesting));

The class does the minimum possible to get text up (all comments removed for brevity)


class CMultilineTextGridItem : public CXTPPropertyGridItem  
{
public:
    CMultilineTextGridItem(CString strCaption, LPCTSTR strValue = NULL, CString* pBindString = NULL);
     virtual ~CMultilineTextGridItem();
     virtual void MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStruct);
     virtual BOOL OnDrawItemValue(CDC& dc, CRect rcValue);
};

The implementation is short too


CMultilineTextGridItem::CMultilineTextGridItem(CString strCaption, LPCTSTR strValue, CString* pBindString)
:CXTPPropertyGridItem(strCaption, strValue, pBindString)
{
    // do nothing
}

CMultilineTextGridItem::~CMultilineTextGridItem()
{
    // do nothing
}

void CMultilineTextGridItem::MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStruct) 
{
    CXTPPropertyGridView* pGrid = GetGrid();
    CDC * dc = pGrid->GetDC();
    CRect rc;
    dc->DrawText(GetValue(), &rc, DT_CALCRECT );
    pGrid->ReleaseDC(dc);
    lpMeasureItemStruct->itemHeight = rc.Height();
}

BOOL CMultilineTextGridItem::OnDrawItemValue(CDC& dc, CRect rcValue)
{
    CRect rcText(rcValue);
    dc.DrawText( GetValue(), rcText, DT_LEFT);
    return TRUE;
}

I hope that helps someone else too; feel free to let me know of any bugs.

In the next release (9.70), you can set the size of individual items, multi-line text support is also added

Wonderful. Is there somewhere that states the release dates?

That's good news... Will this enhancement also be available in the ActiveX version of the control? Thanks.
