Async partial updates with telerik ajax

[ManniAT]

Hi,

I'm messing around with the MS live toolkit.
One thing in this is the Contacts Control.

I got it working like this:

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
    <live:Contacts ID="Contacts1" runat="server" DataDesired="firstname,email" Height="300px" Width="250px" PrivacyStatementURL="~/EIGPrivacy.aspx" OnServerData="Contacts1_OnServerData" />
    <br />
    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <asp:Label ID="lblErg" runat="server"></asp:Label>
        </ContentTemplate>
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="Contacts1" EventName="ServerData" />
        </Triggers>
    </asp:UpdatePanel>
</asp:Content>

But when I try this with RadAjaxManager it does not work (the label does not update)

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="alpPan1">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="Contacts1" EventName="ServerData">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="lblErg" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>
    <telerik:RadAjaxLoadingPanel ID="alpPan1" runat="server" Height="75px" Width="75px" Transparency="5">
        <img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>' style="border: 0;" />
    </telerik:RadAjaxLoadingPanel>
    <live:Contacts ID="Contacts1" runat="server" DataDesired="firstname,email" Height="300px" Width="250px" PrivacyStatementURL="~/EIGPrivacy.aspx" OnServerData="Contacts1_OnServerData" />
    <br />
    <asp:Label ID="lblErg" runat="server"></asp:Label>
</asp:Content>

By the way - using the smarttag on RadAjaxManager to config the manager I don't get the contacts control listed.
But that's not the thing - I'm just curios if the approach with asp:update... can be done with telerik Ajax also.

Hello Manfred,

You can easily observe same behavior as with RadAjax if you set UpdateMode="Conditional" of UpdatePanel from the first code snippet.

RadAjax switches UpdatePanel's UpdateMode to Conditional and that is the reason for this behavior.

Do I understand you right, when I guess that my sample would work (like it does with updatepanel) with AjaxManager if I set the UpdateMode to conditional?

Hello Manfred,

For your conveniance I've prepared example demonstrating how you can use Contacts control with RadAjaxManager.
Please find it attached to this post.

How can I made UpdatePanel's(RadAjaxPanel's) UpdateMode to Always.

Raviraj,

RadAjax use UpdatePanels with UpdateMode = "Conditional" and this is by design.
Attached to my previous post you will find example how to change UpdateMode to "Always".

Hello Sir,

First of all, Thank you for your responce.

I don't have Telerik.Web.UI controls installed. i.e registry <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
I have only radajaxcontrols installed. i.e I have the RadAjax.Net2 in my assembly and in web.config I have added this tag <add assembly="RadAjax.Net2, Version=1.7.0.0, Culture=neutral, PublicKeyToken=3F7B438D1C762D0B"/>

In radA:RadAjaxManager I am unable to find the onajaxsettingcreated.
I have posted the same question in another thread. The link is as below which contains the code snippest also.

Waiting for your responce.

Thank's,

Hello Raviraj,

This forum thread is started under RadControls for ASP.NET AJAX section.
I see that you are using RadControls for ASP.NET.

RadControls for ASP.NET are not build on top of MS ASP.NET AJAX as RadControls for ASP.NET AJAX are. Thus you do not have event AjaxSettingsCreated nor UpdatePanel to change it's mode. 

I hope this helps.
