    <p>We’re developing a web-based application that allows administrators to upload plug-ins. All plug-ins are stored in a special folder outside the app root (say, C:\Plugins) and are dynamically loaded via Assembly.LoadFrom(). This works just fine for the most part: WebControls in the plug-ins are instantiated and loaded, custom classes function as expected, etc.</p> <p>We’re using a custom VirtualPathProvider to get resources out of these plug-ins. So, to get an embedded ASPX file, you’d simply do like, “/MySite/embeddedResource/?Assembly=MyPlugin&amp;Resource=MyPage.aspx”. And that works fine, too: the embedded ASPX file compiles and is served up like a normal page. </p> <p>The problem, however, comes in when an embedded .aspx file (inside of a dynamically loaded plugin) references a class inside that same plug-in assembly. We get compilation errors like, “cannot find type or assembly MyPlugin.” This is odd because, clearly, it’s pulling the .aspx file out of MyPlugin; so how can it not find it?</p> <p>So, I’m hoping you can help me out with this. The plugin would look like this:</p> <p>MyPlugin.dll:</p> <ul> <li>InternalHelperClass.cs</li> <li>MyPage.aspx (resource with no .cs file)</li> </ul> <p>When MyPage.aspx contains something like, “&lt;%= InternalHelperClass.WriteHelloWorld() %>”, the compilation fails. </p> <p>How can we get this to work?</p> <p><strong>UPDATE:</strong></p> <p>We have tried using fully qualified names. No difference. It is impossible to step through - it is a compilation error when you go to the aspx page. Namespaces would not be an issue in this case (since it was from an external plugin dll)</p> <p><strong>UPDATE2:</strong></p> <p>Joel, I think you are onto something. Unfortunately, editing the web.config to include these assemblies isn't part of the design. Basically, we want the plugins to be completely dynamic - drop them in a folder, restart the app, and be ready to go.</p>

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.
