asp.net ajax refresh the UpdatePanel every 30 sec?

I am currently using Timer control inside my update panel to update automatically every 30 sec. However i wanted to use json to do the same thing.

Any suggestions?

Thanks

Hi,

JSON (JavaScript Object Notation) is a lightweight data-interchange format, or it can be viewed as a protocal defining how object is serialized when transporting.

It can't be used to perform actions at a certain interval like Timer.

Please refer to this for more information:http://msdn2.microsoft.com/en-us/library/bb299886.aspx

Hope this helps.
