I'd tend to use delegates to allow events in one control to communicate something to the main page, which can then pass the info on to the other control as appropriate.

The
FindControlmethod looks for a control in the scope of the current naming container, here is the Page instance, so you need to get reference to the naming container of the dropdownlist, maybe the 1.ascx user control, then you can call the FindControl method. However, like Christian said you'd better use the event/delegate to communicate the user controls, it's much more flexible. -

Do you not know how to use delegates ? Google has lots of examples... public class UserControl1 { public delegate void PassAString(string s); public PassAString OnPass; public void SomeEvent(object sender, EventArgs ea) { if (PassAString != null) PassAString("this is the value"); } } public class Form1 { protected UserControl1 u1; protected UserControl2 u2; private void GetAString(string s) { u2.TheString = s; } private void OnLoad(//etc { u1.OnPass += new UserControl1.PassAString(this.GetAString); } } So, the main form hooks up the event, and when it fires, it takes the value it's passed ( whatever that is ) and sends it to the other control.
