Re: Tree Control in DNN

Okay adding child nodes now - not quite sure if the logic is correct but it works!

Now how do I add the clientAPI postback/callback stuff to a node? If I can figure this out this will be almost complete

Well I thought I had this all working now in a new non testing project(module) I cant seem to get items into my tree

Heres some code - can someone point out my flaw?

Private Sub LoadCategories()

Try

'Create a loop that will load the needed records

Dim eNodeNumber As Integer

Dim objTreeNode As DotNetNuke.UI.WebControls.TreeNode

Dim eHelpControl As New eHelpController

Dim eHelpList As ArrayList

eHelpList = eHelpControl.Codegalaxy_eHelp_Get_Category_List(0, ModuleId)

For Each eItem As eHelpInfo_Category In eHelpList

objTreeNode = New DotNetNuke.UI.WebControls.TreeNode '(CType(eItem.Id, String))

objTreeNode.Key = CType(eItem.Id, String)

objTreeNode.ToolTip = eItem.CategoryName

objTreeNode.Text = eItem.CategoryName

objTreeNode.ClickAction = DotNetNuke.UI.WebControls.eClickAction.Expand

eNodeNumber = Me.eHelpTree.TreeNodes.Add(objTreeNode)

Catch exc As Exception

ProcessModuleLoadException(Me, exc)

End Try

End Sub

Re: Tree Control in DNN

Couple things I would try to troubleshoot this.

1) Have you debugged the code and verified that the nodes are indeed being added?

2) If you do a view source on the outputted page, do you see the trees xml in the __dnnVariable hidden control?

3) Are you running against the same code as you were in your tests mentioned above (i.e. same version of webcontrols, and dnn)?

Yeah i finally got it all figured out - thanks for the suggestions though it was looking at the xml that finally brought it to light for me
