When all CExtGridWnd rows are hidden and you call:

false);

RowUnHideAll(

UpdateStaticFilterValueForOuterRow(-1);

The filter value list is incorrectly populated.

 

There are several very critical errors in the following method:

BOOL CtoolbartestDlg::OnCmdMsg(UINT nID, INT nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)
{
    CCmdUI * pCmdUI = (CCmdUI*)pExtra;

    // update UI
    if(nCode == CN_UPDATE_COMMAND_UI)
    {
        switch(nID)
        {
            case ID_ADD:
                pCmdUI->Enable();
                // PROF-UIS TECH SUPPORT: if you are going to change pCmdUI, then return TRUE please
                //break; // PROF-UIS TECH SUPPORT: commented
                return TRUE; // PROF-UIS TECH SUPPORT: added
        }
    }

    return CExtResizableDialog::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);
}

The value filters work correctly after we apply these fixes.

Thanks for the fix ... perhaps you would post the code here so that other can benefit :)

 

Sample project sent.

 

... infact it seems to fail with both 0 & 1 rows visible.  2+ rows works great!
