    <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>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
