[Solved] WSS 3 + WebPart + RadTreeView

[Martin]

Hi,

I am pulling my hair out to get a simple, basic example of a Telerik tree control to work within a WSS 3, Web Part. Below is my simple, simple, Web Part code

Imports System
Imports System.Runtime.InteropServices
Imports System.Web.UI
Imports System.Web.UI.WebControls.WebParts
Imports System.Xml.Serialization

Namespace WebPart

    Public Class FolderHierarchy
        Inherits System.Web.UI.WebControls.WebParts.WebPart

        Public Sub New()
            Me.ExportMode = WebPartExportMode.All
        End Sub

        Protected Overrides Sub CreateChildControls()
            MyBase.CreateChildControls()
            AddTelerikControls()
        End Sub

        Protected Sub AddTelerikControls()
            Dim m_RadTreeFolderHierarchy As New Telerik.WebControls.RadTreeView
            Dim RadTreeNodeRoot As New Telerik.WebControls.RadTreeNode("Martin")
            m_RadTreeFolderHierarchy.Nodes.Add(RadTreeNodeRoot)
            Me.Controls.Add(m_RadTreeFolderHierarchy)
        End Sub

        Protected Sub AddASPControls()
            Dim NormalLabel As New UI.WebControls.Label
            NormalLabel.Text = "Normal ASP Control"
            Me.Controls.Add(NormalLabel)
        End Sub
    End Class

End Namespace

Now if I switch the CreateChildControls to use the AddASPControls function then the web part displays fine. Using the AddTelerik controls it does not.

The problem I am getting is that the web part page returns a '403 - Forbidden' message. There are no other web parts on the page. When I go through the debugger the controls seem to be added OK. Well there are no exceptions thrown. 

I have amended my web.config: I have put these in the correct section.

<trust level="Full" originUrl="" />

<SafeControl Assembly="RadTreeView.Net2, Version=6.2.0.0, Culture=neutral, PublicKeyToken=dbd98e0feff9f06b" Namespace="Telerik.WebControls" TypeName="*" Safe="True" AllowRemoteDesigner="True" />

<SafeControl Assembly="RadTreeView.Net2, Version=6.2.0.0, Culture=neutral, PublicKeyToken=dbd98e0feff9f06b" Namespace="Telerik.RadTreeViewUtils" TypeName="*" Safe="True" AllowRemoteDesigner="True" />

The RadTreeView.Net2.dll file is in the bin directory.
It's file permissions are the same as all the other files in that directory.

I'm lost what to try next. Perhaps because my web.config file contains ASP.NET AJAX settings is upsetting things. A 403 - Forbidden means some kind of security problem, but I don't know what.

Thanks

I have taken the ASP.NET AJAX out of my web.config and no joy. I forgot to mention that I am using Forms authentication (and utilizing my own Membership Provider)

I have managed to sort myself out now.
Strange solution - I switched my authentication type back to Windows and it worked!!! I tried to replicate my problem by switching back to my custom membership provider and it worked!!! So not a very satisfactory, engineering solution. :(
