There is something wrong with xtpControlSplitButtonPopup style toolbar buttons. When I select a button from drop-down choices I expect the selected button to replace the main button. For example check XT's Visual Studio 7 sample app, Class View button (on the right). Even if I select Output from the drop-down the main button stays Class View. Compare it with actual Visual Studio 2003. Also check any other MS applications with split toolbar buttons, e.g. Word, Excel.

It is designed behaviour. You must manually change it. For example "New" button of Outlook don't change self icon.

pControl->SetIconId.

Thanks Oleg

I thought of Outlook's "New" button as an exception rather than a rule. A good exception.

Back to the problem. What would be a good place and time to call SetIconId. Obviously I cannot do it when processing ON_COMMAND as the command could have been triggered by a shortcut or a context menu. Overriding OnExecute in CXTPControl-derived classes (e.g. CXTPControlButton) also does not look like a good idea. This way I will end up overriding lost of classes due to the nature on CXTPControl creation framework (which is somewhat hard-coded; calls like CXTPControlButton::CreateObject do not leave space for flexibility).

Can you recommend a solution?
