Using Script# with ASP.NET

Random notes on this topic.

• Follow instructions here on wiring up the control, specifically the parts about implementing IScriptControl, and overriding OnPreRender() and Render(). However you *must* make one crucial change, or else you'll break ALL javascript on the page.
• You must change this line as follows:

Before:

    var descriptor = new ScriptControlDescriptor("namespace.class", this.ClientID);

After:


    var descriptor = new ScriptControlDescriptor("namespace.class", someOtherControl.ClientID);

The problem is that user controls do not, per se, have an associated HTML control, so it's necessary to place the control's contents inside a Panel. If you do try to create a descriptor using "this", the un-handled error resulting from the $create() call on the client will cause all page-initialization-related Javascript that runs after that point to fail, thus breaking the page in a big way.

GWT Designer, ScriptSharp, Ext JS

Some AJAX things I've been eyeing. Microsoft AJAX just isn't good for certain things, although it's nice.

• GWT, of course. Now 1.6 is in beta.
  
• GWT Designer -- $99 purchase, or $59/year.
  
• Script# - a .NET answer to GWT. Not many widgets, but works with Ext JS (!) via the extsharp project. Was on Codeplex, but removed. Speculation is that MS will integrate it into Visual Studio at some point. Here's a good video/powerpoint presentation on getting started. Helps to navigate your way around the bugs.
