    <p>I need to be able to modify controls from my detailsview programmatically on databind. Right now I'm using this code but I'm getting an "Index was out of range" error.</p> <pre><code>Private Sub dtlApplication_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles dtlApplication.DataBound Dim resumeLink As HyperLink = dtlApplication.Rows.Item(0).FindControl("lnkResume") resumeLink.NavigateUrl = "Resumes/" End Sub </code></pre> <p>I also tried this but got an "Object reference not set to an instance of an object" error.</p> <pre><code>Private Sub dtlApplication_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles dtlApplication.DataBound Dim resumeLink As HyperLink = dtlApplication.FindControl("lnkResume") resumeLink.NavigateUrl = "Resumes/" End Sub </code></pre> <p>I think the problem might be that the detailsview does not have any controls when the page initially loads since it doesn't get them until I select a row in my main gridview. Basically, I am trying to execute this code when I select a row in the gridview, not when the page initially loads. Could that be it? If so, where should I execute this code if not in the detailsview databound?</p> <p>Here is the detailsview and corresponding datasource markup:</p> <pre><code>&lt;asp:DetailsView ID="dtlApplication" runat="server" AutoGenerateRows="false" DataKeyNames="appID" DataSourceID="ds2" CellPadding="0" BorderColor="Transparent" BorderWidth="0px" GridLines="None" HorizontalAlign="Left" Width="459" CssClass="dtlView"&gt; &lt;Fields&gt; &lt;asp:TemplateField showheader="false"&gt; &lt;ItemTemplate&gt; &lt;h3&gt;Resume&lt;/h3&gt; &lt;asp:HyperLink runat="server" ID="lnkResume" Text="View Resume &amp;raquo;"&gt;&lt;/asp:HyperLink&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Fields&gt; &lt;PagerSettings Mode="NextPreviousFirstLast" PageButtonCount="5" FirstPageText="&amp;larr; First" LastPageText="Last &amp;rarr;" nextpagetext="Next &amp;raquo;" previouspagetext="&amp;laquo; Previous" /&gt; &lt;PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" CssClass="paging" /&gt; &lt;/asp:DetailsView&gt; &lt;asp:SqlDataSource ID="ds2" runat="server" ConnectionString="&lt;%$ ConnectionStrings:cn %&gt;" SelectCommandType="StoredProcedure" SelectCommand="sp_SelectApplicationDetail" EnableCaching="true" CacheDuration="600"&gt; &lt;SelectParameters&gt; &lt;asp:ControlParameter Name="appID" ControlID="gvAdmin" PropertyName="SelectedValue"&gt;&lt;/asp:ControlParameter&gt; &lt;/SelectParameters&gt; &lt;/asp:SqlDataSource&gt; </code></pre>

Guidance
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.
