[Solved] Update label outside from RadAjaxPanel on asyncpostback

[cuepack]

Hi together,
we have the following scenario in our Web Application.

Masterpage with 4 ContentPlaceholders, every page uses the masterpage.

We would like to update a label that is placed outside from the RadAjaxPanel.

Please look at the following code, in this case we click on "cmdTabOne" the
"cmdTabOne_Click" event fires fine and the "lblHeadline" label will be updated correct.
The Label "lblContextInfo" which is outside from the RadAjaxPanel will not updated.

<asp:Content ID="Content0" ContentPlaceHolderID="head" Runat="Server">
    ...
</asp:Content>
<asp:Content ID="Content1" ContentPlaceHolderID="HeaderPlaceHolder" Runat="Server">
    ...
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="leftPanelPanel" Runat="Server">

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

</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="leftPanelContent" Runat="Server">

        <telerik:RadScriptManager ID="RadScriptManager1" runat="server" />
        <telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

        // Main Content
        <div>
            <asp:Label ID="lblHeadline" runat="server" Text=""></asp:Label>
        </div>

        <div>
            <asp:LinkButton ID="cmdTabOne" runat="server" CssClass="Tab_active" onclick="cmdTabOne_Click">Tab One</asp:LinkButton>
            <asp:LinkButton ID="cmdTabTwo" runat="server" CssClass="Tab_inactive" onclick="="cmdTabTwo_Click">Tab Two</asp:LinkButton>
        </div>


        </telerik:RadAjaxPanel>

</asp:Content>

 protected void cmdTabOne_Click(object sender, EventArgs e)
  {
     lblHeadline.Text = "Headline for Tab One";
     lblContextInfo.Text = "Contextinfo for Tab One";
  }

  protected void cmdTabTwo_Click(object sender, EventArgs e)
  {
     lblHeadline.Text = "Headline for Tab Two";
     lblContextInfo.Text = "Contextinfo for Tab Two";
  }

Any Ideas?

Thank you for your help.

Best regards

Hello Cuepack,

RadAjaxPanel is a lightweight control that lets you update a part of your web page with AJAX while keeping the rest of the page working with postbacks.
To achieve the desired functionality you should use RadAjaxManager control, which offers a complete solution for turning a postback-based application into an AJAX-driven one
Please find more information in the following articles:

Hi Pavlina,

thank you for your quick response and your hints.
I got it managed with the RadAjaxManager and it works fine now.

Best regards.
