    <p>I'm trying to create a rendering template for my forms which need complex validations treatments. the rendering template is working fine wwith :</p> <pre class="lang-xml prettyprint-override"><code>&lt;XmlDocuments&gt; &lt;XmlDocument NamespaceURI="http://schemas.microsoft.com/sharepoint/v3/contenttype/forms"&gt; &lt;FormTemplates xmlns="http://schemas.microsoft.com/sharepoint/v3/contenttype/forms"&gt; &lt;Display&gt;ListForm&lt;/Display&gt; &lt;Edit&gt;ChaisTemplate&lt;/Edit&gt; &lt;New&gt;ChaisTemplate&lt;/New&gt; &lt;/FormTemplates&gt; &lt;/XmlDocument&gt; &lt;/XmlDocuments&gt; </code></pre> <p>and with my ascx :</p> <pre><code>&lt;%@ Control AutoEventWireup="true" CodeBehind="ChaisTemplate.ascx.cs" Inherits="TransactionsFormsTemplates.ControlTemplates.ChaisTemplate, TransactionsFormsTemplates" Language="C#" %&gt; &lt;%@ Assembly Name="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %&gt; &lt;%@ Register TagPrefix="SharePoint" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" Namespace="Microsoft.SharePoint.WebControls" %&gt; &lt;%@ Register TagPrefix="wssuc" TagName="ToolBar" Src="~/_controltemplates/ToolBar.ascx" %&gt; &lt;%PageLoad(this, null);%&gt; &lt;SharePoint:RenderingTemplate ID="ChaisTemplate" runat="server"&gt; ..... </code></pre> <p>but I can't have any control mappings in my code behind (in the webapp bin with cas policies, and it's correctly deployed) this :</p> <pre><code> &lt;asp:TextBox runat="server" ID="test"&gt;&lt;/asp:TextBox&gt; </code></pre> <p>is null when it comes to :</p> <pre><code> public partial class ChaisTemplate : System.Web.UI.UserControl { protected TextBox test; </code></pre> <p>so everytime I call test.Text on functions, I get a nullreferenceexception, because test is never mapped to my ascx textbox. why ? plus, the PageLoad is never called like in classic asp.net pages, even with &lt;%PageLoad(this, null);%> at the beginning. however every event works :</p> <pre><code> &lt;asp:Button runat="server" ID="button" OnClick="button_OnClick"/&gt; </code></pre> <p>this will actually call button_OnClick in my code behind. But all my properties are null because not mapped.</p> <p>did I miss something? </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.
