Hello support. I’ve emailed you may times regarding this issue (dating back the January 22nd 2011) and have yet to receive a satisfactory response. Maybe today will be my lucky day eh? Especially as I’ve just renewed my support agreement ;)

Hang on a minute ... I don’t think this is want I asked for. I am after a fix for (Show All) being incorrectly ticked having edited a column that is filtered. Please clarify.

We are sorry. We forgot to provide you with one updated method in your test project:
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();
return true;
}
}
// command
if(nCode == CN_COMMAND && nID == ID_ADD)
{
if(pExtra == NULL)
{
CMemFile _file;
CArchive _arStore( &_file, CArchive::store );
bool bHaveState = m_wndGrid.FilterStateForOuterRowSerialize( _arStore, true, 0L, false, false );
_arStore.Close();
if( bHaveState )
{
_file.SeekToBegin();
m_wndGrid.RowUnHideAll( false );
}
m_wndGrid.RowUnHideAll(false);
m_wndGrid.RowRemove(0, 1, false);
m_wndGrid.RowInsert(0, 1, false);
CExtGridCellStringDM* pCell;
pCell = STATIC_DOWNCAST(CExtGridCellStringDM, m_wndGrid.GridCellGet(0L, 0L, 0, 0, RUNTIME_CLASS(CExtGridCellStringDM)));
pCell->TextSet(_T("00"));
// // m_wndGrid.RowUnHideAll( false );
// // m_wndGrid.UpdateStaticFilterValueForOuterRow(-1);
// m_wndGrid.CExtGridWnd::OnGridFilterUpdateForRows(0L, -1L, true, NULL);
m_wndGrid.OnSwUpdateScrollBars();
if( bHaveState )
{
CArchive _arLoad( &_file, CArchive::load );
VERIFY( m_wndGrid.FilterStateForOuterRowSerialize( _arLoad, true, 0L, false, false ) );
_arLoad.Close();
}
m_wndGrid.OnSwDoRedraw();
}
return true;
}
return CExtResizableDialog::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);
}

To resolve the issue you reported we had to serialize filtering conditions and then un-hide and rescan the value filters. This approach makes dynamic value filters working better. You can re-open value filters list box menu and it will contain all the available values, including hidden. Please update the source code for the following methods:
void CExtGridCellHeaderFilter::stat_CalcPlainUniqueValuesForColumn(
CExtArray < CExtSafeString > & arrUniqueStringValues,
const CExtGridWnd & wndGrid,
LONG nColNo
)
{
__EXT_DEBUG_GRID_ASSERT( int( arrUniqueStringValues.GetSize() ) == 0 );
CExtGridWnd * pWndGrid = const_cast < CExtGridWnd * > ( &wndGrid );
CMemFile _file;
CArchive _arStore( &_file, CArchive::store );
bool bHaveState = pWndGrid->FilterStateForOuterRowSerialize( _arStore, true, 0L, false, false );
_arStore.Close();
if( bHaveState )
{
_file.SeekToBegin();
pWndGrid->RowUnHideAll( false );
}
LONG nRowCount = wndGrid.RowCountGet();
for( LONG nRowNo = 0L; nRowNo < nRowCount; nRowNo++ )
{
const CExtGridCell * pCell = wndGrid.GridCellGet( nColNo, nRowNo );
if( pCell != NULL )
{
CExtSafeString str( _T("") );
pCell->TextGet( str );
arrUniqueStringValues.InsertUnique( str );
}
} // for( LONG nRowNo = 0L; nRowNo < nRowCount; nRowNo++ )
if( bHaveState )
{
CArchive _arLoad( &_file, CArchive::load );
VERIFY( pWndGrid->FilterStateForOuterRowSerialize( _arLoad, true, 0L, false, false ) );
_arLoad.Close();
}
}
void CExtGridCellHeaderFilter::stat_CalcPlainUniqueValuesForRow(
CExtArray < CExtSafeString > & arrUniqueStringValues,
const CExtGridWnd & wndGrid,
LONG nRowNo
)
{
__EXT_DEBUG_GRID_ASSERT( int( arrUniqueStringValues.GetSize() ) == 0 );

CArchive _arStore( &_file, CArchive::store );

if( bHaveState )
{

}
