    I've used a part of the code from the RSSFeed Live demo in my own web user control.
    When the RSS source isn't available the RSS reader fails.

    How can I handle errors in loading the RSS feed so it won't make the application crash, and also, how can I set the text for the prev and next buttons from code behind?



    <telerik:RadListView ID="RadListView1" runat="server" OnNeedDataSource="RadListView1_NeedDataSource"
        AllowPaging="true" ItemPlaceholderID="Panel1" PageSize="3">
            <div class="layoutWrapper">
                <div class="rssHeaderWrapper" title="Copyright, 2011 Honda Motor Co., Ltd. and its subsidiaries and affiliates. All Rights Reserved.">
                    <div class="rssSubHeader">

                    <div class="rssHeader">
                        rss <span class="rssHeadingDate">
                            <%# DateTime.Now.ToLongDateString().ToLower() %></span>
                <br />
                <asp:Panel ID="Panel1" runat="server">
                <div style="width: 100%; text-align: center;">
                    <asp:ImageButton ID="PrevBtn" runat="server" CommandName="Page" CommandArgument="Prev"
                        AlternateText="<" CssClass="rssButtons" ImageUrl="images/iconPrev.png" />

            <table class="rssTable" title='Item <%# (Container as RadListViewDataItem).DataItemIndex %>, Page <%# RadListView1.CurrentPageIndex + 1 %>'

                        <div class="rssTitle">

                            <a href='<%# (Container.DataItem as XmlNode)["link"].InnerText %>' class="qsfSubtitle">

                        <span class="rssDescription">

    Hello Thomas,

    In the code behind wrap the doc.Load(rssUrl); inside Try-Catch statement, to handle the case when the RSS is not available.
    See this help topic about accessing controls inside the ListView:

    All the best,
