Body
We use the WPF WebBrowser control to display an embedded page. On Windows 8 we observe a strange jumping behavior of elements with css position:fixed while scrolling. <img src="https://i.stack.imgur.com/76qCv.jpg" alt="position:fixed is jumping when scrolling"> The same page works fine in IE10 on Windows 8 (also FF, Chrome) and in the WPF WebBrowser control on Windows 7. Has anyone seen this behavior before and knows a fix for the jumping motion? Is it possible the .NET Version 4.5 used on the test machine (Surface with Win 8) be the Problem as compared to the .Net Version 4 on the dev machine? The Development Environment: <ul> <li>Windows 7</li> <li>Microsoft Visual Studio 2010 Version 10.0.30319.1 RTMRel</li> <li>Microsoft .NET Framework Version 4</li> </ul> The Test Environment: <ul> <li>Surface</li> <li>Windows 8</li> <li>Microsoft .NET Framework Version 4.5</li> </ul> Client XAML: <pre><code><Window x:Class="EmbeddedBrowserTest.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid> <WebBrowser HorizontalAlignment="Stretch" Name="webBrowser" VerticalAlignment="Stretch" Grid.Row="1" /> </Grid> </Window> </code></pre> Demo Page HTML: <pre><code><!DOCTYPE html> <html> <head> <meta http-equiv="X-UA-Compatible" content="IE=9" /> <title>minimal position fixed example</title> <style> body { margin: 0px } .header{ height: 60px; width: 960px; background-color: #cccccc; top: 0px; left: 0px; position: fixed; z-index: 10; } .content{ padding-top: 60px; height: 420px; width: 960px; background-color: lightsteelblue; } </style> </head> <body> <div class="header"> header </div> <div class="content"> content 1 2 3 4 5 6 7 </div> </body> </html> </code></pre>

1. COI believe the WebBrowser control in WPF is actually just a wrapped WinForms control, I wonder if this is related? I wonder what would happen with a embedded web browser in a WinForms project?

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.
