Hilary,
Sorry for butting in on this conversation, but this is similar to what I was trying to do. I have already tried going down your path, but rather than show/hide with details directly below each competancy I was creating a show/hide summary. My issue is I am hiding the summary until some hits the unhide radio button. Then I created buttons so when clicked they will jump to the project on the form. My code looks like this (VB):
Public Sub btnToProj_Clicked(ByVal sender As Object, ByVal e As ClickedEventArgs)
Dim myNav As XPathNavigator = Me.MainDataSource.CreateNavigator()
myNav.SelectSingleNode("//my:myFields/my:sectStatusReport/my:sectLeader/my:sectProject/my:sectionProjectDetails", Me.NamespaceManager).Select("ProjectAnchor")
End Sub
Project Anchor is a text field where I set focus rather then trying to go to the project name. I do not get an error or any movement when attempting this.
Any thoughts or help will be greatly appreciated.
