How to hide popup button in SplitButton?

Hi Marcin,

While you can't hide the drop-down button portion without re-templating the control, I believe you can set a SplitButton.PopupCommand and handle its CanExecute to determine whether that portion is enabled. It's what drives IsPopupButtonEnabled.

I have a problem using this solution. when i try to disable the popup, the entire split button is also gets disabled. i use two different commands - one for the button and one for the popup. when the popup command binding 'canExecute' returns false, the entire button is disabled though the 'canExecute' of the button command returns true.

Hi Eli,

Yes that is true. Looking at the code, it appears to be by design because one of the Ribbon spec requirements is:
"Both the menu and button portion of Split Button controls MUST be disabled on the Ribbon if all of the items in the menu are inactive."

So unfortunately there isn't a way to keep the button active but the popup disabled since that would violate the ribbon requirement.
