  1. POASP.NET: "Object Required" when repeating LinkButtons in an UpdatePanel
    text
    copied!<p>I have an UpdatePanel which has a Repeater repeating LinkButtons. When I click a LinkButton, the page does a partial postback, then I get a javascript error: "Object required". I tried debugging the javascript, but couldn't get a call stack. If I remove the UpdatePanel, the LinkButtons do a full postback, and they disappear from the page. How can I get this UpdatePanel to work?</p> <pre><code>&lt;ajax:UpdatePanel ID="wrapperUpdatePanel" runat="server" UpdateMode="Always"&gt; &lt;ContentTemplate&gt; &lt;asp:Repeater ID="endpointRepeater" runat="server" OnItemDataBound="EndpointDataBound"&gt; &lt;HeaderTemplate&gt; &lt;div class="sideTabs"&gt; &lt;ul&gt; &lt;/HeaderTemplate&gt; &lt;ItemTemplate&gt; &lt;li&gt; &lt;asp:LinkButton ID="endpointLink" runat="server" OnClick="EndpointSelected" /&gt; &lt;/li&gt; &lt;/ItemTemplate&gt; &lt;FooterTemplate&gt; &lt;/ul&gt; &lt;/div&gt; &lt;/FooterTemplate&gt; &lt;/asp:Repeater&gt; &lt;/ContentTemplate&gt; &lt;/ajax:UpdatePanel&gt; </code></pre> <p>binding code:</p> <pre><code>protected void Page_Load(object sender, EventArgs e) { if (!this.IsPostBack) { this.SelectedEndpoint = Factory.Get&lt;IEndpoint&gt;(Enums.EndPoints.Marketing); } IEndpointCollection col = EndpointCollection.GetActivelySubscribingEndpointsForPart(this.Item); if (this.Item.IsGdsnItem) col.Add(Factory.Get&lt;IEndpoint&gt;(Enums.EndPoints.Gdsn)); if (col.Count &gt; 0) col.Insert(0, Factory.Get&lt;IEndpoint&gt;(Enums.EndPoints.Marketing)); this.endpointRepeater.DataSource = col; this.endpointRepeater.DataBind(); if (this.endpointRepeater.Items.Count &gt; 0) { LinkButton lb = this.endpointRepeater.Items[0].FindControl("endpointLink") as LinkButton; this.EndpointSelected(lb, new EventArgs()); } } </code></pre> <p>thanks, mark</p>
