Hi,

We are using Webgrid inside an update panel.

See the screenshot for the reference.We have Listbox on the LHS side and Webgrid on RHS side.

There are two buttons >> << which will move the items from listbox to webgrid and vice versa.

When we click on the << >> buttons we are getting javascript error on webgridUI.js.

See the screenshot WErrror.If we did not place the webgrid inside the update panel we are not getting this javascript error.

Please advice.it is urgent

Regards,

Madhavan
