If I want to inject a globally scoped array variable into a page's client-side javascript during a full page postback, I can use:

this.Page.ClientScript.RegisterArrayDeclaration("WorkCalendar", "\"" + date.ToShortDateString() + "\"");

to declare and populate a client-side javascript array on the page. Nice and simple.

But I want to do the same from a async postback from an UpdatePanel.

The closest I can figure so far is to create a .js file that just contains the var declaration, update the file during the async postback, and then use a ScriptManagerProxy.Scripts.Add to add the .js file to the page's global scope.

Is there anything simpler? r iz doin it wrong?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
