Not able to set the value of dropdown list in tabstrip

[Nikhil]

Hi,

I have a hidden field whose value is updated on link click. And on this link click I am reloading a entire tab strip for the new value of hidden filed.
The tab which is active is working fine and I am able to set the hidden field's value to the drop down present in the tab.

But when I click on another tab in tab strip having another drop down, I am not able to set the hidden field's value to the drop down in now selected tab.

Please help.

Thanks,
Nikhil
