    <p>I am using ASP.NET MVC 3 with .NET 4.0. I have a model on which one of the properties requires that HTML content be allowed. I have placed the <code>AllowHtml</code> attribute on my model property which allows HTML on that property. That works by itself. </p> <p>I am also using the <a href="http://www.uploadify.com/" rel="nofollow">Uploadify</a> flash uploader on other parts of my website. Due to <a href="http://www.uploadify.com/documentation/uploadify/using-sessions-with-uploadify/" rel="nofollow">problems</a> with flash and sessions, I'm using some code similar to the code in a <a href="http://code.google.com/p/swfupload/source/browse/swfupload/trunk/samples/samples/asp.net/Global.cs.asax" rel="nofollow">swfupload example</a> to allow my file upload access to session data. Basically I'm accessing the <code>Request.Form</code> collection directly in the <code>Application_BeginRequest</code> handler.</p> <p>The problem I'm running into is that when the form that allows HTML is posed I get a <code>HttpRequestValidationException</code> when the code in the <code>Application_BeginRequest</code> handler access the <code>Request.Forms[key]</code> collection.</p> <p>Like I said in the beginning, I've tried the <code>AllowHtml</code> attribute. I've also tried disabling validation at the action and controller level using the <code>ValidateInput(false)</code> attribute, but I believe I'm too early in the request life cycle for those to apply. Is there anyway to access the <code>Request.Form</code> collection containing "potentially dangerous" data without disabling request validation for the entire site?</p>

    2. COYes, but that will disable validation for the entire site. I would prefer to keep it enabled if possible.

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).
