    <p>Lets say I have a data table with the columns ImageUrl, Text, LinkUrl and Title.</p> <p>I databind this to a repeater and displays everything without any issue. However, LinkUrl can be empty and then I want the code to be like the one below. If the LinkUrl contains a string/link then I want to wrap the image with a link to the URL. Please ask questions if I need to clarify more.</p> <p>Example code:</p> <pre><code>&lt;asp:Repeater runat="server" ID="rptImageGallery"&gt; &lt;ItemTemplate&gt; &lt;div class="slide"&gt; &lt;asp:Image ID="Image1" runat="server" ImageUrl='&lt;%#UrlHelper(DataBinder.Eval(Container.DataItem, "ImageUrl"))%&gt;'&gt; &lt;h2&gt;&lt;%# DataBinder.Eval(Container.DataItem, "Title") %&gt;&lt;/h2&gt; &lt;p&gt;&lt;%# DataBinder.Eval(Container.DataItem, "Text")%&gt;&lt;/p&gt; &lt;/div&gt; &lt;/ItemTemplate&gt; &lt;/asp:Repeater&gt; </code></pre> <p>Code behind:</p> <pre><code>DataTable dt = new DataTable(); dt = collListItems.GetDataTable().AsEnumerable() .Where(a =&gt; Convert.ToString(a["Published"]) == "1") .CopyToDataTable(); rptImageGallery.DataSource = dt; rptImageGallery.DataBind(); </code></pre> <p>So if the current row contains a link in LikUrl then I want the repeater to present something like this</p> <pre><code>&lt;asp:Repeater runat="server" ID="rptImageGallery"&gt; &lt;ItemTemplate&gt; &lt;div class="slide"&gt; &lt;asp:Image ID="Image1" runat="server" ImageUrl='&lt;%# UrlHelper(DataBinder.Eval(Container.DataItem, "FileLeafRef"))%&gt;' /&gt; &lt;a href='&lt;%# DataBinder.Eval(Container.DataItem, "LinkUrl")%&gt;' runat="server"&gt;&lt;%# DataBinder.Eval(Container.DataItem, "Title") %&gt;&lt;/h2&gt;&lt;/a&gt; &lt;p&gt;&lt;%# DataBinder.Eval(Container.DataItem, "Text")%&gt;&lt;/p&gt; &lt;/div&gt; &lt;/ItemTemplate&gt; &lt;/asp:Repeater&gt; </code></pre> <p>Any suggestions on how to achieve this?</p> <p>Edit: something weird with the post. When I go Edit I can see the correct code - slick Save and it doesn't update my code example. Anyway, in the last code part I want a link wrapping the image or image text.</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.
