    <p>I have a Repeater contol bound to a custom object (an EntitySpaces query) and have noticed there are a couple of ways to conditionally format the values being displayed. </p> <p>1) From my aspx I can call a method in my code-behind and pass through the bound value and use that to drive any conditional logic:</p> <pre><code> &lt;a class="star" href="&lt;%#MakePackageSelectionUrl((int)DataBinder.Eval(Container.DataItem, "PackageId"))%&gt;"&gt; and then in the code-dehind: protected string MakePackageSelectionUrl(int packageId) { return string.Format("/Packages/NoAjax/ToggleStar.aspx?p={0}&amp;amp;s={1}&amp;amp;st={2}", packageId, _streamId, (int)_phase); } </code></pre> <p>2) I can hook into the ItemDataBound event, retrieve e.Item.DataItem as a DataRowView and then go crazy:</p> <pre><code> protected void PackageList_ItemDataBound(Object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType != ListItemType.Item &amp;&amp; e.Item.ItemType != ListItemType.AlternatingItem) { return; } DataRowView details = (DataRowView)e.Item.DataItem; EncodePackageName(e, details); EncodeStatusName(e); DisplayStarImage(e, details); } private static void EncodePackageName(RepeaterItemEventArgs e, DataRowView dr) { HtmlAnchor p = (HtmlAnchor)e.Item.FindControl("packageLink"); if (p != null) { p.HRef = string.Format("/Packages/View.aspx?p={0}", dr["packageId"]); p.InnerHtml = HttpUtility.HtmlEncode((string)dr["packageName"]); } } </code></pre> <p>I've also noticed that using e.Item.FindControl() in the code-behind requires runat="server" on the control in the aspx which has a nasty habit of encoding ids and generally messing up the HTML.</p> <p>I'm keen to hear from anyone that has come up with a nice approach for dealing with these sorts of issues.</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.
