Dear CodeJock,

 I am creating a Property Grid to have a bespoke GridItem in a Pane. The Grid Item will consist of a CXTComboBoxEx and a CXTButton.

There exists a problem when trying to get the Horizontal scrolling enabled in the CXTComboBoxEx.

Here is a code snip -:

 // The class declaration.

class CTraSerFPCustomInPlaceListBox : public CXTComboBoxEx

I then create the control in the OnSelect handler for my GridItem in the Pane. This works fine and my controls are displayed as I expect them to be. Here is the code snip -:

DWORD dwStyle = WS_BORDER|WS_CHILD|WS_VISIBLE|WS_VSCROLL| WS_HSCROLL |CBS_DROPDOWNLIST;

m_wndComboBox.Create( dwStyle , rcCombo, (CWnd*)m_pGrid, 1972);

m_wndComboBox.SetHorizontalExtent(400);

I have a message map set up for these classes so I can handle some simple interaction.

Notice that I have specified the creation of the class CXTComboBoxEx with  the WS_HSCROLL and a subsequent call to SetHorizontalExtent.

If I use CXTComboBoxEX - it does not work.

If I derive my class from CComboBox - the Horizontal scroll bars appear.

If I am missing something please let me know is there a work around- or otherwise confirm this as a bug ?

Other than this seemingly minor issue - keep up the good work - I look forward to your reply.

regards

Kevin.
