    <p><code>runat="server"</code> is not going to make your control run inside a browser. I think you have a fundamental misunderstanding of how ASP.NET works. Web controls don't run inside the browser. They run on the server and produce HTML code that is sent to the browser, and may include various HTML controls and Javascript snippets.</p> <p>Any mechanism for client-side code other than HTML5 (Javascript) is going to require client-side support, i.e. the plugin you were trying to avoid. Of the possible plugins, the one that's closest to WinForms and most portable is going to be Silverlight. That uses WPF, not WinForms, for user interface components. There is a WPF host for WinForms controls, but I don't know if you can use that from inside Silverlight.</p> <p>Also, you need a bunch of special compile options in order to use C++/CLI with Silverlight. By default C++/CLI generates machine-specific native code which runs outside the browser sandbox. That's going to be blocked by any user with a sane security configuration. You're going to need to emit pure MSIL code and enable "Partial Trust". Then you're going to run into trouble with the native component you're wrapping.</p> <p>There's pretty much no advantage to doing this in a web browser. Just have the user download a WinForms application. You can use ClickOnce or another packaging technology to keep the application updated to the latest version on your site, but neither ASP.NET nor any of the browser technologies is going to play nicely with your control. Your other option is a rewrite, not of the wrapper, but of the whole OpenGL rendering layer, to use WebGL instead.</p>

    1. CO+1 for clarifying my web ecosystem doubts. It has to run in a browser in order to integrate it with other web components we made. Isn't there a way to get unmanaged Direct3D9 apps to run inside a browser? I would be willing to go for a plugin if it allowed me to run this. I think I saw some browser games which use Direct3D, cannot recall them now.

    2. COThose games which use Direct3D aren't part of the webpage. They are written as web browser plugins, like Unity3D (which makes them very non-portable, since they have to match the OS, machine architecture, and particular browser), and only the game data files are loaded from the website. (The game data files contain enough scripting to make what appears to be a number of different games using a single plugin). You'd probably be better off putting the other web components inside a WebBrowser control inside your app.

    3. COWe ended up redoing most of it using just HTML5 + Javascript, since we didn't strictly need strictly 3D stuff. WebGL looked really good, but Internet Explorer didn't support without installing a plugin.

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).
