Dropdown list item data bind

Hello PPl,

I have had a long paining doubt in ma mind from couple of days.

I have a query regarding code on dropdown list item.

Query: I am sure about the process of binding a data source to a dropdown list and populating the items on to dropdown control.

But, all I need is to display the item information on selection from dropdown list. what I mean is, ex: I have populated items named with property: User ID. By populating the user id items into dropdown control, all the user IDs have been bound. Now, on-selecting particular item in the control, i want to retrieve the information from data base through anothee datasource and populate the particular user ID information such as User Name, User Last Logon, User Task Status in a grid view.

Please do respond me ASAP.

Cheers
