Hi,
You can do that following steps below:
- Create a method in .ascx.cs file with input param as string
- In this method populate grid by using input passed
- From the main file on SelectedIndexChange event of drop down call function created in .ascx.cs file as UserControlClassName.MethodNameand pass the selected item as input param
I assume u r using C#.
Try this if u still have some problem then post ur problems.
