    I Get a javascript error when I put the following control in the same page as a ScriptManager.

    If i remove the
            <telerik:RadScriptManager ID="RadScriptManager1" runat="server"
    tag, no error happen.
    What can i do to solve this?

    Custom control
    Imports System.ComponentModel 
    Imports System.Web.UI 
    Imports Telerik.Web.UI 
    Public Class ValidatingTextbox 
        Inherits Textbox 
        Implements IPostBackEventHandler 
        Public Delegate Sub OnBlurDelegate(ByVal sender As ObjectByVal e As EventArgs) 
        Public Event Blur As OnBlurDelegate 
        Protected Overrides Sub OnInit(ByVal e As System.EventArgs) 
            If Not Page.ClientScript.IsClientScriptBlockRegistered("OnBlurTextBoxEvent"Then 
                Page.ClientScript.RegisterStartupScript(MyBase.GetType"OnBlurTextBoxEvent", GetScript, True
                Attributes.Add("onblur""OnBlurred(" & UniqueID & ",'')"

    The page looks like this:

                                    TabIndex="5" runat="server" Width="141px" AutoPostBack="True"/> 
            <br /> 
    the code behind
    Partial Public Class test
        Inherits System.Web.UI.Page 
        Private Sub txtRecordTest2_Blur(ByVal sender As ObjectByVal e As System.EventArgs) Handles txtRecordTest2.Blur 
            'Some thing is done 
        End Sub 
    End Class

    Hello Jonathan GrandMaison,

    It seems that the problem is in the MIcrosoftAjax.js
    What happens if you replace RadScriptManager with the asp:ScriptManager? I suppose you will get the same error.
