Hello,

My answer is related to CAB: you should add a CommandHandler for the object in the ToolbarsManager. The command handler should call the helper method that performs the indicated actions. So when you want to "programmatically fire ToolbarButton click" you only have to call the helper method.

When you add an invoker for a command, the CAB creates an event handler for you, under the hood. When the event is fired by the control, the CAB searches for the command handler with the same name you have provided when you have added the invoker. This is why the command handler method has to be public and has to have the signature of a standard event handler. The beauty of this is that you can place your command handler anywhere in the WorkItem. For example you can add the invoker in a presenter and the command hanler in a service or the module controller.

This is how I see the code:

public void AnyInitializationMehod()
{
    // somehow get the reference to the ToolbarButton instance
    ToolbarButton button1 = ...;
    WorkItem.Commands["Button1CommandName"].AddInvoker(button1, "ToolClick");
}

[CommandHandler("Button1CommandName")]
public void OnButton1CommandHandler(object sender, EventArgs e)
{
    Button1CommandHelperMethod();
}

private void Button1CommandHelperMethod()
{
    // code to run when the button 1 is invoked by user click or programmatically
}

HTH,
Emanuel
