Childwindow datagrid tooltip error COM: HRESULT E_FAIL

Jan 23, 2012 at 10:14 AM

When using the tooltips in a childwindow, in which I have a datagrid, the above error occurs when showing a tooltip and scrolling in the datagrid (OnDataContextChanged in ToolTipService class).

Does anybody have a solution for this?
