Hello Krasimir,

I tried the mechanism from your sample in my application, where the ribbon is filled at runtime.

In the first try, I got exceptions like these all the time:

UnhandledException: System.InvalidOperationException: An item with the specified TargetId 'XYZMYITEMKEY' being added to the QuickAccessToolbar is not registered with the associated XamRibbon.

That may be caused by I first put the ButtonTools into the RibbonGroups, the groups into the Tabs and then added the filled tabs into the ribbon.

It has improved after I changed this to:
First add tabs, then add groups to tabs, then add items (ToolButtons) to groups.

Now, RibbonGroups and ButtonTools from within the RibbonGroups can properly be added to the QAT and I can save/restore their keys and types.

But still, some items cause the exception above when trying to restore the QAT-Items, as if they were not correctly registered with the ribbon. But I know they are present in the ribbon (just not in the first tab, maybe that's the point?),

Is there any way to make sure that each key is correctly registered with the ribbon?

Everything is ok. Thanks

Finally, i solved my problem by deleting  "(ID)"  characters in Id. It seems to fix it and, then, it works.

Is it the good way to proceed?

Hello,

Sorry for answering so late. Due to troubles with my email server, i didn't received any email notification for your previous answer.

It doesn't work fine for me, an error occurs when reloading : "An item with the specified TargetId '(ID)634359570788694218703564304' being added to the QuickAccessToolbar is not registered with the associated XamRibbon"

Indeed, this Id is different tan the one I can see in Visual Studio. Moreover, the Id is also different when I open the project on another computer. However, the one read is the one written previously. The problem seems to be that runtime Ids are different than designtime Ids. Is there any way to "freeze" it?

Sincerely
