[Solved] RadAjaxManager to work with Web Service menu items

[Eduardo]

Hi,

I'm not sure I'll be able to explain correctly, but let's try.

I created a RadMenu that is populated by a web service (following the examples provided). But now I was trying to use the RadAjaxManager to call a server-side code to, on the menu items click, populate another control (in this case another RadMenu playing the role of a Breadcrumb). The problem is that these menu items that are created via web service doesn't fire the server-side event. the root (which I manually added as it is static) works fine.

Basically, this is what I have on the aspx, which I think explains a bit of what I mean

    <div>
        <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
        </telerik:RadScriptManager>
        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="rmModules">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="mnBreadCrumbs" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>
        <telerik:RadMenu ID="rmModules" runat="server"
            Skin="Outlook" EnableEmbeddedSkins="false" EnableEmbeddedBaseStylesheet="false"
            OnClientItemClicking="onClicking" OnItemClick="rmModules_ItemClick"
            EnableViewState="false" EnableAjaxSkinRendering="false" EnableOverlay="false">
            <WebServiceSettings Path="NavigationItems.asmx" Method="GetMenuCategories" UseHttpGet="false" />
        </telerik:RadMenu>
        <telerik:RadMenu ID="mnBreadCrumbs" runat="server">
        </telerik:RadMenu>
    </div>

Is it possible to do something like what I want to do? or the only way to do that is via client-side javascript?

Thanks,
Eduardo

Hi Eduardo,

I could not reproduce the problem in a simple page.

Please find attached a sample project.

Let me know what is different in your case.

P.S. In the second menu I am adding a fake invisible item because otherwise there is a javascript error when the menu contains no items (this is already fixed in the latest internal builds).

Hi,

Sorry for taking so long to get back to you. I finally had some time to play with your sample. It really worked all fine. But I don't know what is going wrong with my main project, the postback event specific to that control doesn't fire, the strange thing is that it still works with other controls.

Is there anything on ASP.NET that I can do to get back the event to work again?

Thanks,
Eduardo

Hi Eduardo,

Unfortunately we are not sure where this problem comes from. One reason for the ItemClick event not to fire is having the NavigateUrl property of the menu item set. In that case clicking the menu item navigates instead of postback.

Hi Albert,

I didn't have the NavigateUrl set up for that menu. I think it is an ASP.NET issue. Anyway, I resolved this by creating a new page, adding the controls again and copying all the code. It was a lot of work, but at the end it worked.

Thanks,
