Question

I am having a problem updating a listview’s databinding when inside a update panel. The listview is to do a databind and return some user names.
I have tested the databind by triggering it from an asp button and it works fine like so.

protected void getFacebookFriends(object sender, EventArgs e)
    {
        List<testResult> getFriends = (from i in lqDataContext.test(base.UserId) select i).ToList();
        lvFacebookFriends.DataSource = getFriends;
        lvFacebookFriends.DataBind();

    }

when I try do this via ajax using

<telerik:RadAjaxPanel ID="updateFriends" runat="server" OnAjaxRequest="updateFriends_AjaxRequest">


 function invokeAjaxRequest() {
        $find("<%= updateFriends.ClientID%>").ajaxRequestWithTarget("<%= updateFriends.UniqueID %>", 97);
    }

protected void updateFriends_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
List getFriends = (from i in lqDataContext.test(base.UserId) select i).ToList();
lvFacebookFriends.DataSource = getFriends;
lvFacebookFriends.DataBind();
updateFriends.EnableAJAX = false;
}

I can see in debug that I get through updateFriends_AjaxRequest without error but the ui has not change.

Thanks for helping me understand this.

Just wrap it in a regular update panel. The postback will be caught and the listview will re-render with the new information asynchronously.
