There are 2 scenarios which causes this error.

First scenario:

Selecting a treeview control which is inside the combobox which will cause an ajax process
while a radgrid is within the page and while the code behind are inside a try catch block.
When the code is not in a try catch block, nothing appears.

Second scenario:

Inside a radwindow or normal window(appears using window.open):
Selecting a treeview control which is inside the combobox which will cause an ajax process.
Although this is without a radgrid but error occured, is this due to child window?

I've read some articles about setting something at the web config file but i'm not sure if
its the appropriate solution for me. I'm using version v.2011.2.712.40

Regards,
Dexter
