Make sure you have binded them properly while Page loads.It should be like
if(!IsPostBack)
{
your dropdown binding code here
}

Hey there,

Its a little hard to guess the problem from that little code and information.

But I think you are binding your Repeater control after the DropDownList's selectedIndexChanged event.
check your code and see if the binding code for repeater is being called after/in that event.

hope it helps

Good luck..
