    <p>I have a DetailsView with 1 of its field converted to TemplateField to be able to manipulate the InsertItemTemplate that contains a TextBox (cf: code below). The problem is that I cannot access to that TextBox Properties in my code behind... and I really don't get it :( Here is my aspx code (portion of it):</p> <pre><code>&lt;asp:DetailsView ID="_DetailsView" ClientIDMode="Static" runat="server" Height="50px" Width="125px" AllowPaging="True" AutoGenerateRows="False" DataKeyNames="IDUniv" DataSourceID="EntityDS" OnModeChanging="_OnModeChanging"&gt; &lt;Fields&gt; &lt;asp:TemplateField HeaderText="DateUpdateUniv" SortExpression="DateUpdateUniv" ConvertEmptyStringToNull="False"&gt; &lt;InsertItemTemplate&gt; &lt;asp:TextBox ID="TextBoxInsertItem" runat="server" Text='&lt;%# Bind("DateUpdateUniv") %&gt;'&gt;&lt;/asp:TextBox&gt; &lt;/InsertItemTemplate&gt; &lt;ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:CommandField ShowDeleteButton="True" ShowEditButton="True" ShowInsertButton="True" /&gt; &lt;/Fields&gt; &lt;/asp:DetailsView&gt; &lt;asp:EntityDataSource ID="EntityDS"&gt; </code></pre> <p>and in the Page_LoadComplete event Handler I have something like this:</p> <pre><code>private void Page_LoadComplete(object sender, EventArgs e) { if (_DetailsView.HasControls()) { Control _InsertDate = _DetailsView.FindControl("TextBoxInsertItem") as TextBox; if (_InsertDate != null) { _InsertDate.Text = "something"; } } } </code></pre> <p>but the following code is wrong: _DetailsView.FindControl("TextBoxInsertItem") and also this doesn't work: _InsertDate.Text = "something";</p> <p>I found an interesting article, but still...: <a href="http://www.devproconnections.com/article/aspnet2/getting-under-the-detailsview-control" rel="nofollow">http://www.devproconnections.com/article/aspnet2/getting-under-the-detailsview-control</a></p> <p>can someone help me find my path ? How to find this TextBoxInsertItem control and interact with it ? Thanks</p>

    2. CO_DetailsView object seems to have no controls. I changed my test from "if (_DetailsView.HasControls())" to "if (_DetailsView.DataMember.Length > 1)" and in Debug mode, the Length = 0

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).
