MS Office Forum / Outlook / Programming Add-Ins / May 2006Event Handler for Folder Selected
I found event handlers for regular outlook items, but how do I insert an event handler for other folders? I have 2 buttons on a custom toolbar, and several application specific folders. I need to enable or disable the toolbar buttons depending on which folder the user selects. Ok, I have an event handler working, but now I am trying to figure out how to enable/disable toolbar buttons on the fly. You would need a method to access the CommandBarButton objects that are your buttons and set their Enabled property True or False as warranted by the current state.

I created access to the button objects when they are created. They're not null, but when setting the Enabled property to true, the buttons remain grayed out. Are you getting a valid button object? Is the Enabled property returning an error? I've found that especially in WordMail that even if a button object is a valid object that most of its properties and methods aren't valid even in the button Click event handler. In those cases I have to actually reinstantiate the button object using FindControl and then I can set properties such as Picture and Mask and set visibility and enabled.

The return from the button.Enabled = true is true and button.Enabled = false is false; I will try using FindControl instead. Sure it's the right button in the right Inspector or Explorer? In my wrapper classes for Inspectors or Explorers I can set Enabled and Visible true or false based on business logic conditions and it works. The only time I have to re-instantiate the button objects are in WordMail Inspectors.
