Infragistics Forums

I am trying to hook Command handler to Infragistics ButtonTool in Shell Common ToolBar. I am trying have same view open in multiple tabs so that it allows to create two users at same time. For the first tab, it adds invoker without any issue but when adding buttontool on creating the second tab, it throws this error "ex = {"Unable to access the specified event for the specified invoker."}. In the workItem, I added Activated, Deacivated events to make the button invisible same way as how it is done in BankTeller app.Let me know if you have any suggestion.

Thanks,
Prasad
