Hide a Toolbar Item?

GeorgeFaraj — Tue, 06 Mar 2012 17:51:35 GMT

In an ArcEngine application, if I add a command (or tool) to a toolbar can I then hide that command (or tool)?

I can do this:

int itemIndex = toolbar.AddItem("esriControls.ControlsMapFullExtentCommand", 0, -1, false, 0, esriCommandStyles.esriCommandStyleIconOnly);
IToolbarItem item = toolbar.GetItem(elementTool);

But I see nothing in IToolbarItem that sets visibility. Is this even possible?

I didn't see the abillity to toggle visibility of a ToolbarItem in the API, other than removing the item from the Toolbar given an item index.

Uggggghhhhh! Now I have a chicken and egg problem. (I want to use a command index in a ToolbarMenu before it is created - I figured if I could load it first in the toolbar and then hide it that would solve my problem. So now I need 2 toolbars because 1 doesn't really work.)

Did you look at ICommandItem? The delete method just removes the command from the commandbar. The docs indicate you can add that command back at a later time.

That's Desktop stuff - I'm Engine only.

I did find a solution that worked. I instantiate a seperate toolbar and load all my commands into that toolbar in any order I want and then I share that toolbar's CommandPool with the UI toolbar. I can then load the UI toolbar however I want. Sure would be nice if I could just hide an item tho. Can't see why that has never been requested.
