Hi,

I am dynamically adding a UserControl to RadPanelItem.

And in UserControl I am registering some JavaScript block.(I am giving code is below)

Problem: I can't get the javascript function to fire.
Also, if I viewsource aspx page I can't see html code for usercontrol and javascript block.

UserControl:

    
            <%@ Control Language="vb" AutoEventWireup="false" CodeBehind="UserControl1.ascx.vb" Inherits="UserControl1" %>  
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="Telerik" %>  
        
            <Telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" EnableEmbeddedScripts="true" ></Telerik:RadAjaxPanel>  
        
            <table width="100%">  
        
                <tr>  
        
                    <td>  
        
                    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>     
        
                        <asp:Button ID="buttonClear" runat="server" Text="Clear" Width="46" UseSubmitBehavior="false"  
        
                            CausesValidation="false" OnClientClick="ClearMe();return false" />  
        
                    </td>  
        
                </tr>  
        
            </table>

User Control Page_load Event:

    
                    Dim script1 As New StringBuilder 
        
                    script1.AppendLine("<script language='javascript' type='text/javascript'>") 
        
                    script1.AppendLine("    function ClearMe(){ ") 
        
                    script1.AppendLine("        alert();") 
        
                    script1.AppendLine("        document.getElementById(" & TextBox1.ClientID & ").value = ''; ") 
        
                    script1.AppendLine("</script>") 
        
                    'I tried 
        
                'Me.Controls.Add(New LiteralControl(clearScript.ToString())) 
        
                    'I tried 
        
                    'ScriptManager.RegisterStartupScript(Parent.Page, Me.GetType(), "ClearBox", script1.ToString, True) 
        
                    'I tried 
        
                    If Not Parent.Page.ClientScript.IsStartupScriptRegistered("ClearBox") Then 
        
                        Parent.Page.ClientScript.RegisterStartupScript(Me.GetType(), "ClearBox", script1.ToString, True) 
        
                    End If

In the Page_Load of Default.aspx I am calling usercontrol

    
                    Dim uControl As myUserControl = CType(Page.LoadControl("~/MyProject/UserControls/myUserControl.ascx"), myUserControl) 
        
                    uControl.ID = "myUniID" 
        
                    Dim RadPanelItem11 As RadPanelItem = RadPanelMain1.FindItemByValue("MYTemplateHolder") 
        
                    RadPanelItem11.Items(0).Controls.Add(uControl) 
        
                    RadPanelItem11.Expanded = True

Any ideas??

Hello TelNew,

I think it will be best if you can open a support ticket and send us a simple running project (incl. your custom skin, CSS, images, DB backup if needed and so on) demonstrating the problem (and step-by-step instructions on doing so). In that way we can reproduce and pinpoint the problems you're facing on our side, understand the logic of your application and provide a solution.
