RadAjaxManager does not work with RadioButtons/RadioButtonLists

[Nate Pinchot]

Hello,
It appears that RadAjaxManager does not work properly with RadioButton or RadioButtonList controls.
If I Have the following code:

    <telerik:RadAjaxManager ID="ramAjax" runat="server" EnableHistory="True" OnAjaxRequest="ramAjax_AjaxRequest">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="rbAllWorkOrders">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="rgSearchResults" LoadingPanelID="ralpLoading" />
                    <telerik:AjaxUpdatedControl ControlID="pageTime" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="rbMyWorkOrders">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="rgSearchResults" LoadingPanelID="ralpLoading" />
                    <telerik:AjaxUpdatedControl ControlID="pageTime" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>


            <asp:RadioButton runat="server" ID="rbAllWorkOrders" GroupName="rbgWorkOrderFilter" Text="All Work Orders" AutoPostBack="True" OnCheckedChanged="filter_ValueChanged" Checked="True" />
            <asp:RadioButton runat="server" ID="rbMyWorkOrders" GroupName="rbgWorkOrderFilter" Text="My Work Orders" AutoPostBack="True" OnCheckedChanged="filter_ValueChanged" />

When the page loads, the "All Work Orders" RadioButton will be selected by default. If you click the "My Work Orders" button the RadAjaxManager will "trigger" an "ajax postback" causing the loading panel to display and filter_ValueChanged will get called. If you then click "All Work Orders" after that, the RadAjaxManager will not trigger anything, the event will not get called and the loading panel does not display.
The same holds true for setting a "default selected" option in a RadioButtonList. If the AjaxSetting is removed from the RadAjaxManager for these RadioButton controls or RadioButtonList control everything works as expected, however a postback is caused which is why I want to use RadAjaxManager.
Please help.

Hello Nate,

Please find an attached sample project, which shows the correct behavior of RadioButtons ajaxified with RadAjaxManager. Let us know what the difference in your case is.

Apparently the trick is including the ControlID of the RadioButtons or RadioButtonList in the AjaxUpdatedControl of itself. Thanks.

Quick update as was facing same problem, problem is gone and we do not need to have RadioButtonList's ID as an updated control, but if we set ClientIDMode as "static" the problem arises again, so if we remove that attribute, there's no problem.

Regards.
