Prevent child control inside the updatepanel to refresh the updatepanel

let say i have 2 UpdatePanels UP1 and UP2. Up1 contains a dropdownlist with 3000 items. When selectedindex of the dropdownlist is changed, it fires a partial postback to refresh the controls inside the UP2 which uses trigger. but at the same time it also refreshes the UP1which i want to avoid. and i also need this dropdown list to be inside the Updatepanel because the selected index is changing during partial postback.

Currently what i have done is i took this dropdownList out of updatepanel and the UP2 gets refreshed using trigger of that dropdownlist, and when it is required to update the the dropdown list i 'm injecting the javascript code in partial postback to do this.

any better work around to achieve this.

Thanks in Advance

Problem accessing the Items with a Cascading dropdown

I got a web page, inside there is a userControl with two cascading dropdown list, and i got a grid as well (it isn't inside the usercontrol). The cascading ddl are working fine, they get populated and everything, my problem is when I try to load a record from de grid I have to check if this record is inside the second cascading ddl (if it has been populated), and I cannot see the items inside my second cascading ddl (neither the normal ddl) so I cannot check if the record exists, Does anyone know how to tackle this? as well I presume that I will have problems trying to set the selected value once I've been able to check if it exists or not, Any ideas??

Thanks very much!!!!!!!

I fail to reproduce the issue. Can you show me your code?
