Update a AjaxPanel from new window postback

[Linh Hoang]

Hi all,

I have a AjaxPanel consisting of a radgrid and a button; when I clicked the button, a new RadWindow was opened; on the new opened window, there are a check list and a submit button. Now I want to select items from check list, click submit button to update the AjaxPanel. How could I do this?

So much appriciated for any suggestion.

Hello Linh,

In order to implement the behavior you are looking for you should consider using RadAjaxManager. It was built to handle more complex scenarios.

The following code snippets outline the approach with simple Label and Button controls. You can follow the same approach in your scenario.

Markup:

<telerik:RadAjaxManager runat="server" ID="RadAjaxManager1">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="Button2">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="Panel1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>


<asp:Panel runat="server" ID="Panel1">
    <asp:Label ID="Label1" runat="server" />

    <asp:Button ID="Button1" Text="Open Window" runat="server" OnClientClick="clientClick(); return false;" />

</asp:Panel>
<telerik:RadWindow runat="server" ID="RadWindow1">
    <ContentTemplate>
        some content
        <br />

        <asp:Button ID="Button2" Text="Update Panel" runat="server" OnClick="Button2_Click" OnClientClick="hideWindow();" />

    </ContentTemplate>

</telerik:RadWindow>

JavaScript:

function clientClick(sender, args) {
    $find("<%= RadWindow1.ClientID %>").show();
}

function hideWindow(sender, args) {
    $find("<%= RadWindow1.ClientID %>").hide();
}

Code-behind:

protected void Button2_Click(object sender, EventArgs e)
{
    // add server-side logic here

    Label1.Text = DateTime.Now.ToString();
}

I hope this helps.
