ExtJsExtender x Coolite - part 2

In the last I blogged about coolite studio advantages over ExtJsExtender controls now I am going to talk about the ExtJsExtenders advantage

1. Has more controls that coolite ( coolite does not support the grid)
2. Free and open source
   

One of the advantages of using the asp.net ajax library is that it allows you to develop a control without mixing javascript with C# (or whatever server-side language) , and that makes it easier to write, debug and maintain the code.
