Cannot update control inside RadWindow

[Jerry]

Hi!

I've been testing this for hours now.

If I add a RadWindowManager with one RadWindow and a Label in it and set it to VisibleOnPageLoad="true".

And a button which changes the Label's text to Label1.Text = "Hello World".
The button is inside a RadAjaxPanel.

I can't get the label to update the value inside the RadWindow.

No matter what I do. Can you give me a simple example on how to make the window update the label when I've pressed the button.

Regards, Jerry

Hello Jerry,

Here is a sample code to achieve the same.
aspx:

<telerik:RadAjaxPanel ID="Panel1" runat="server">

     <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button2_Click" />

  <telerik:RadWindowManager ID="RadWindowManager1" VisibleOnPageLoad="true" VisibleStatusbar="false"

            ReloadOnShow="true" runat="server" Skin="Sunset" EnableShadow="true">

     <Windows>

          <telerik:RadWindow ID="RadWindow1" runat="server" Behaviors="Close">

            <ContentTemplate>

               <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>   

            </ContentTemplate>

         </telerik:RadWindow>

   </Windows>

   </telerik:RadWindowManager>

</telerik:RadAjaxPanel>

C#:

protected void Button2_Click(object sender, EventArgs e)
 {
   Label mybox = RadWindow1.ContentContainer.FindControl("Label1") as Label;
   mybox.Text = "Hello";
 }

Thanks,
Shinu.

Is there a way to achieve this client side?

Hello Roger,

Please examine the following online demo: http://demos.telerik.com/aspnet-ajax/window/examples/contenttemplatevsnavigateurl/defaultcs.aspx. It shows the way to access controls in the ContentTemplate of the RadWindow via JavaScript. Basically you need their ClientID as the RadWindow is an INaming container in this case. This is a general case and you would have the same behavior with other container controls (master pages, update panels, etc).

Hi,

Hope this will help,

 function Button2_Click(sender, args) {
          document.getElementById('RadWindow1_C_Label1').innerHTML = "test";
          return false;
      }


Thanks,
Dhamu
