Hi
Vishnu<o:p></o:p>
<o:p> </o:p>
There are several ways to do that:<o:p></o:p>
You should
set the Autopostback property of the First DropDown to true. Then on the
SelectedIndexChanged
event get the selectedvalue and use a new
connection, command and Datareader (if they are
not defined as the class member) and fire the query on the selected value
and populate the second combo.<o:p></o:p>
Second you
can create a javascript for that and do all
these operations on Client side. But it is quite tedious job. <o:p></o:p>
(if
you need I can send you the code for that)<o:p></o:p>
<o:p> </o:p>
<o:p> </o:p>
Hope this will help you out.<o:p></o:p>
<o:p> </o:p>
