Opening modalpopextender inside a user control in web application

Question

I have two user controls in my web application. Both user controls have modalpopupextender. When i am adding scriptmanager to both the user controls it gives a error that :

Only one instance of a scriptmanager can be added to the page

Hence i provided scriptmanager for only one user control. Here the popup works fine. But in other usercontrol as i am not adding scriptmanager popup does not work. How can i solve this issue?

Answer 1

在母版页或容器页上使用scriptmanager 。
