    <p>Currently i'm familiarizing myself with ASP.NET and i've stuck on a problem with dynamic content inside "ItemTemplate" of "Repeater". Here is my code:</p> <pre><code>&lt;asp:Repeater ID="sidebarRepeater" runat="server"&gt; &lt;ItemTemplate&gt; &lt;li&gt; &lt;a href="#&lt;%# DataBinder.Eval(Container.DataItem, "Id") %&gt;"&gt;&lt;%# DataBinder.Eval(Container.DataItem, "Name") %&gt;&lt;/a&gt; &lt;/li&gt; &lt;/ItemTemplate&gt; &lt;/asp:Repeater&gt; </code></pre> <p>I'm getting a list of links with href == Id of current item and text of this item. The problem is, that i need a "Onclick" asp.net handler for each of those links (this is menu of "Master" User control, and on each click i shall change contents of child user control, according to selected item in master).</p> <p>Any tips?</p> <p>Edit: I've already tryed to use LinkButton like:</p> <pre><code>&lt;li&gt; &lt;asp:LinkButton ID='&lt;%# DataBinder.Eval(Container.DataItem, "Id") %&gt;' runat="server" OnClick="ChangeSomething"&gt; &lt;%# DataBinder.Eval(Container.DataItem, "Name") %&gt; &lt;/asp:LinkButton&gt; &lt;/li&gt; </code></pre> <p>Edit2: Currently my markup looks like this:</p> <pre><code>&lt;li&gt; &lt;input type="hidden" value="&lt;%# DataBinder.Eval(Container.DataItem, "Id") %&gt;" &lt;asp:LinkButton runat="server" ID="LinkButton_Office" Text='&lt;%# DataBinder.Eval(Container.DataItem, "Name") %&gt;'/&gt; &lt;/li&gt; </code></pre> <p>In this case, it draws only a "hidden input" element only for first item in repeater.</p> <p>Edit3: full listing of what i currently have(only <code>&lt;li&gt;&lt;/li&gt;</code> rendered into actual HTML):</p> <pre><code>&lt;div class="row"&gt; &lt;div class="twelve column"&gt; &lt;div class="row"&gt; &lt;div class="side-bar"&gt; &lt;nav&gt; &lt;ul&gt; &lt;asp:Repeater ID="sidebarRepeater" runat="server"&gt; &lt;ItemTemplate&gt; &lt;li&gt; &lt;asp:LinkButton ID="linkSidebar" runat="server" CommandArgument='&lt;%# DataBinder.Eval(Container.DataItem, "Id") %&gt;' Text='&lt;%# DataBinder.Eval(Container.DataItem, "Name") %&gt;' OnClick="linkMenu_Click"&gt;&lt;/asp:LinkButton&gt; &lt;/li&gt; &lt;/ItemTemplate&gt; &lt;/asp:Repeater&gt; &lt;/ul&gt; &lt;/nav&gt; &lt;/div&gt; &lt;div class="page"&gt; &lt;asp:PlaceHolder runat="server" ID="contentPlaceholder" /&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>Also i forgot to say, that this is actually a .Net user control for Umbraco project. Datasource is attached for repeater in <code>protected void Page_Load(object sender, EventArgs e)</code> method.</p>

    2. COI've tryed to do so, but i don't know how to properly insert ID and Name of my listed code into it. When i've did insert through DataBinder.Eval like for this 'a' tag for LinkButton, it just didn't rendered.

    3. COYou don't need to put all informations into your `LinkButton`, you just have to know which item was clicked, the rest can be obtained from other controls which might be hidden(f.e. for the `ID` you could use a `HiddenField`). You get the other controls via `FindControl` on the `NamimgContainer` of the `LinkButton` in it's `Click` event.

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.
