Was wondering if someone could give me some direction on this. I've spent a decent amount of time on it and don't seem to be getting anywhere: I have a hidden field that I'm trying to parse out of an HTML document in VB.Net. I'm using a System.Windows.Controls.WebBrowser control in a WPF application and handling the LoadCompleted event. Inside the LoadCompleted event handler I do something like this: <pre><code>Dim htmlDocument As mshtml.IHTMLDocument2 = Me.WebBrowser.Document Dim allElements As mshtml.IHTMLElementCollection = htmlDocument.body.all Dim hiddenField As mshtml.IHTMLInputElement = allElements.tags("hidField") </code></pre> The hidden field that I'm trying to access is declared in my .aspx file as such: <pre><code><asp:HiddenField runat="server" ID="hidField"/> </code></pre> The problem is that this <code>allElements.tags("hidField")</code> is returning null. Am I doing something wrong with the mshtml library? I don't have much experience with it and gathered that I needed to do something like this to find my hidden field element. Let me know if you need more info. Thanks for the help in advance. EDIT Here's is my final working solution for anyone interested: <pre><code> Dim htmlDocument As mshtml.IHTMLDocument2 = Me.WebBrowser.Document Dim allElements As mshtml.IHTMLElementCollection = htmlDocument.body.all Dim allInputs As mshtml.IHTMLElementCollection = allElements.tags("input") For Each element As mshtml.IHTMLInputElement In allInputs If element.type = "hidden" And element.name.Contains("hidField") Then MessageBox.Show(element.value) End If Next </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.
