Hi;

I use drag & drop to drop information from different custom windows to the report control. Whenever I drag over a row while an inplace button is visible, the button flickers permanently.
I checked the code and found out that the commented (by myself) code is responsible for that:

void CXTPReportInplaceButton::OnPaint()
{
CPaintDC dc(this);

if (pControl)
{
// if (m_bDraw)
pControl->GetPaintManager()->DrawInplaceButton(&dc, this);
// m_bDraw = !m_bDraw; //to eliminate flickering
}
}

But when I remove the code the control flickers (button disappears when clicking into the item and reappears immediately). This other kind of flickering was reported in the forum about 1 1/2 year ago.

Any ideas how to fix this, or how to get rid of all inplace buttons while a drag&drop operation is in progress?
