    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"> 
            </telerik:RadScriptManager> 
    tag, no error happen.
    What can i do to solve this?

    Telerik Version=2008.3.1125.35

    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 Object, ByVal e As EventArgs) 
        Public Event Blur As OnBlurDelegate 
     
     
        Protected Overrides Sub OnInit(ByVal e As System.EventArgs) 
            MyBase.OnInit(e) 
            If Not Page.ClientScript.IsClientScriptBlockRegistered("OnBlurTextBoxEvent") Then 
                Page.ClientScript.RegisterStartupScript(MyBase.GetType, "OnBlurTextBoxEvent", GetScript, True) 
                Attributes.Add("onblur", "OnBlurred(" & UniqueID & ",'')") 
            End If 
        End Sub 
     
     
     
        Protected Sub OnBlur() 
            RaiseEvent Blur(Me, EventArgs.Empty) 
        End Sub 
     
        Private Function GetScript() As String 
            Return "function OnBlurred(control, arg)" & vbCrLf & _ 
                    "{" & vbCrLf & _ 
                    "    __doPostBack(control, arg);" & vbCrLf & _ 
                    "}" 
        End Function 
     
        Public Sub RaisePostBackEvent(ByVal eventArgument As String) Implements System.Web.UI.IPostBackEventHandler.RaisePostBackEvent 
            OnBlur() 
        End Sub 
     
    End Class 
     

    The page looks like this:
    </head> 
    <body> 
        <form id="form1" runat="server"> 
        <div> 
            <br /> 
            <telerik:RadScriptManager ID="RadScriptManager1" runat="server"> 
            </telerik:RadScriptManager> 
             <cc1:ValidatingTextbox CssClass="input" ID="txtRecordTest2" Style="left: 200px; position: absolute;" 
                                    TabIndex="5" runat="server" Width="141px" AutoPostBack="True"/> 
            <br /> 
        </div> 
        </form> 
    </body> 
    </html> 
    the code behind
    Partial Public Class test
        Inherits System.Web.UI.Page 
     
        Private Sub txtRecordTest2_Blur(ByVal sender As Object, ByVal 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.
