Using right frame from EditTree

I have created a plugin in PlugInArea.EditTree where I wish to list a number of tasks. Clicking one of the tasks should open a corresponding settings page in the right frame of edit mode. What is the correct way to do this? Before I have used constructs like:

<a href="#" onclick="window.parent.commandEvent(window, new window.parent.commandDescriptor('','<%=ResolveUrl("~/path/to/settingspage.axps")%>',''));">Link<a>

But is this really the way to go?

    No suggestions? I have now run into a problem. I get a viewstate encryption exception, and according to various forum posts on the Internet this is because of a duplicate aspnet form. The page i load above has it's own form, and I guess the Edit mode masterpage also contains a form. So I need an other way of using the masterpage to load my settings page?

    Why use viewstate on that code? make a placeholder around it and turn of viewstate. That way it dont write to viewstate and the problem will go away Wink (hopefully)

    Good suggestion! I tried to set EnableViewState=false on the form element of the "settingspage.aspx" loaded in the right frame, and also on a new placeholder in the form. Neither worked. As soon as the form posts back i get:

    Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

    And I don't have a web farm, it's on my developer PC :)

    Solved it. Apparently the form Action attribute could not be empty (=current page), I had to specifically set it to the aspx name. I suppose the Iframe structure of the edit interface confuses aspnet, or something...

    I found an alternative to this:

    <a href="~/path/to/desiredPage.axps" target="EditPanel">LinkText</a>

    this works :)
