I am simply trying to display a value from label control, the value is setting from the code behind. But I could not find any good example. Either telerik told me that this is not possible or give me a good example. Please note that if I set the text in the markup it works but setting its value from the code behind does not work.

I am opening a popup from jquery to display the label control.

 <telerik:RadWindow ID="RadWindow1" runat="server" Behaviors="Resize, Close"
                                Modal="True" ShowContentDuringLoad="False" VisibleStatusbar="False" AutoSize="False"
                                Width="455" ReloadOnShow="True" Height="260" Title="Opening Balance">

 <asp:Panel ID="Panel​1" runat="server">
                                                                <table class="margin-all-10">
                                                                        <td class="label">
                                                                            Bank: <asp:Label ID="lblLabel1"  Text="" runat="server"></asp:Label>

 Protected Sub AddBegBalance_Command(ByVal sender As Object, ByVal e As CommandEventArgs)

            lblLabel1.Text = "Some Text"
    ScriptManager.RegisterStartupScript(UpdatePanel1, UpdatePanel1.GetType, "alert1", "Display();", True)

    End Sub​

  <script language="javascript" type="text/javascript">

function ShowModifyAddBalan() {
           var _wndwAddOpenBalan = $find("<%= RadWindow1.ClientID %>");

Hi Amir,

Can you please provide a little more details on the exact moment in which you want to change the text of the label?
  • Which is the event handled by the AddBegBalance_Command function?
  • Where is the UpdatePanel1 placed?
  • Do you have AjaxManager on the page, or any other update panels?

I am attaching a very simple page demonstrating how the label can be updated on a button click. The page is also containing RadAjaxManager in order to update the text of the label via AJAX, without closing the window. If your scenario is different though, please, send us a runnable sample demonstrating the configuration used by so we will be able to advice you further.
