Sharepoint: An unexpected error has occurred.

[Matthew]

Greetings,

I downloaded the ASP.NET AJAX trial and I'm trying to use the grid control. I set up my web.config for AJAX 3.5, added the Telerik.Web.UI to the GAC, and added the necessary <SafeControls> to the web.config.

I'm trying to make a Sharepoint web part that just displays the grid. I'm following along in the help file but I've run into a problem. When I make any referece to a Telerik object Sharepoint display the very helpful error page. 

"An unexpected error has occurred."

I've sifted though all the log files that I can possibly locate and have found absolutely nothing to go on. 

Here is the code that I'm using for the OnInit. This right out of the help file. 

Protected Overloads Overrides Sub OnInit(ByVal e As EventArgs)

            MyBase.OnInit(e)

            Page.ClientScript.RegisterStartupScript(GetType(DealerPortal), Me.ID, "_spOriginalFormAction = document.forms[0].action;_spSuppressFormOnSubmitWrapper=true;", True)

            If Me.Page.Form IsNot Nothing Then

                Dim formOnSubmitAtt As String = Me.Page.Form.Attributes("onsubmit")

                If Not String.IsNullOrEmpty(formOnSubmitAtt) AndAlso formOnSubmitAtt = "return _spFormOnSubmitWrapper();" Then

                    Me.Page.Form.Attributes("onsubmit") = "_spFormOnSubmitWrapper();"

                End If

            End If

            Dim scriptManager As ScriptManager = scriptManager.GetCurrent(Me.Page)

            If scriptManager Is Nothing Then

                scriptManager = New RadScriptManager()

                Me.Page.Form.Controls.AddAt(0, scriptManager)

            End If

If I comment out the "RadScriptManager()" call then the web part will show up just fine. Otherwise I get the dreaded Sharepoint error page. 

I haven't even got to exposing the RadGird yet. It's gotten that bad. 

I've added the necessary reference and Imports statement to the class object. 

Does ANYONE have ANY ideas? 

Thanks,

-Matt

One other question:

Do I have to use the AJAX version? Can I just use the ASP.NET version? AJAX sounds exciting and all, but this is horrible. 

Thanks again.

Hello Matthew,

I'm afraid that I'm not sure what may caused this error from the given details. Can you please post your full webpart declaration? Please make sure you have added correct reference to RadControls assembly to your webpart project.
