Hi There,
Just FYI; I have integrated LLBLGen Pro with Visual WebGui (http://www.visualwebgui.com).
Without any templates or additional code generation, I have been able to create a library for on-the-fly CRUD & Search screens. You pass in a RootEntity, and you can edit the RootEntity, it's child relations, etc. on the web. Undo/Cancel functionality is integrated.
Very much recommend Visual WebGui as a user-interface framework. VWG is based on the WinForms API, but for ASP.NET. You can create drag-n-drop Forms & UserControls just like WinForms, all within Visual Studio. For over 1.5+ years, I haven't written a single line of CSS/JavaScript/DHTML. All Forms, UserControls, and custom Controls are 100% full AJAX.
Just letting you know what is all possible when you combine some very well designed frameworks, namely LLBLGen Pro & Visual WebGui.
