    <p>It might help to know a little bit more about what your are trying to do. If your end goal is to get any of the properties from your bound object you can just cast the dataItem from the <a href="http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.listviewcommandeventargs.aspx" rel="nofollow noreferrer">ListViewCommandEventArgs</a> of the ItemCommand event. You don't need to retain the index or call FindControl at all.</p> <p>Here is an example of how to get the bound Customer object.</p> <p><strong>ListView</strong></p> <pre><code>&lt;asp:ListView runat="server" id="Customers" ItemCommand="Customers_ItemCommand"&gt; &lt;LayoutTemplate&gt; &lt;ul&gt; &lt;asp:placeholder runat="server" id="itemPlaceholder" /&gt; &lt;/ul&gt; &lt;/LayoutTemplate&gt; &lt;ItemTemplate&gt; &lt;li&gt; &lt;asp:Button runat="server" id="Select" CommandName="Select" /&gt; &lt;%# Eval("Name")%&gt; &lt;/li&gt; &lt;/ItemTemplate&gt; &lt;/asp:ListView&gt; </code></pre> <p><strong>CodeBehind</strong></p> <pre><code>public void Page_Load() { if (!Page.IsPostBack) { this.Customers.DataSource = GetCustomers(); this.Customers.DataBind(); } } public void Customers_ItemCommand(object sender, ListViewCommandEventArgs e) { if (e.CommandName == "Select") { if (e.Item.ItemType != ListViewItemType.DataItem) return; var customer = ((ListViewDataItem)e.Item).DataItem as Customer; if (customer != null) { // Now work directly with the customer object. Response.Redirect("viewCustomer.aspx?id=" + customer.Id); } } } </code></pre> <p><strong>Edit:</strong> In addtion when you cast the item to a ListViewDataItem, then you also expose a ((ListViewDataItem)e.Item).<a href="http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.listviewdataitem_properties.aspx" rel="nofollow noreferrer">DataItemIndex</a> property that might help you.</p>

    2. COThe point is you might not need the index if you can just get direct access to your dataItem.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
