    <p>Ok I'm stumped, I have a good 10 other pages all using the same layout etc all working fine, but I created a new page and cannot get it to work. </p> <p>I have noticed what is causing the error but I don't know why or how to fix it. Have a look at the code below, </p> <p>Its a form with <code>runat=server</code>, <a href="http://www.ext.net" rel="nofollow">Ext.Net</a> Resource Manager, Viewport, Tab Panel and 2 Panels, no code behind. </p> <p>When I load this i get the dreaded <code>this.el is null</code> in Firefox and <code>Uncaught TypeError: Cannot set property 'setSize' of null</code> in Chrome. But alas I remove the form tag and everything works as it should. Now you might say well just remove the form tag, but I cant will add asp.net controls later that needs this tag.</p> <p>Markup:</p> <pre><code>&lt;%@ Page Language="C#" AutoEventWireup="true" CodeFile="PriceSetting.aspx.cs" Inherits="V2_RenewalsProcess_PriceSetting" %&gt; &lt;%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %&gt; &lt;DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head runat="server"&gt; &lt;title&gt;Ovott V2&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;form id="pricesetting" runat="server"&gt; &lt;ext:ResourceManager ID="ResourceManager1" runat="server" /&gt; &lt;ext:Viewport ID="Viewport1" runat="server" Layout="border"&gt; &lt;Items&gt; &lt;ext:TabPanel ID="TabPanel1" runat="server" Region="Center"&gt; &lt;Items&gt; &lt;ext:Panel ID="Panel5" runat="server" Title="To Be Submitted" Border="false"&gt; &lt;/ext:Panel&gt; &lt;ext:Panel ID="Panel6" runat="server" Title="Awaiting Approval"&gt; &lt;/ext:Panel&gt; &lt;/Items&gt; &lt;/ext:TabPanel&gt; &lt;/Items&gt; &lt;/ext:Viewport&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

    1. COProbably really isn't a form issue, since when removing the runat="server" or the complete tag only results in the controls not loading the client scripts. Check if the TabPanel or Wievport control have a property called "Size" and if you're setting it to a "null" value somewhere or if you're not setting a value for it at all, try to set a default one and check if that works.

    2. COI just tested it again the only thing i changed was removing the runat="server" from the form tag and it works perfectly, by the way the code in this post is the only code on the page so I dont set size or anything anywhere else.

    3. COJezus, I didn't notice at first, but your DOCTYPE tag is formed wrong, it's missing a "Q" in front "<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">"

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).
