Hi All,

I am trying to use a Webdropdown Control with Multi selection Option Enable and Which is placed in a Update Panel/without Update Panel in Asyc mode as I donot want the control have any postback . based on the Items Selected in this Control  i am trying to fill another Dropdown Controls. 

But This is Giving the Following Javascript error and Stopping the Funcionality of the Controls.

and if i debug this error found that it is happening in the scripts generated by the infragestics Controls. i tried different way to eliminate the error by changing the control properties page properties. but nothing worked.

Please help me with this error as I have got stuck with this from last 3 days.

Thanks & regards
