I'm getting the following error:
......................
Multiple controls with the same ID '_1' were found. FindControl requires
that controls have unique IDs.
.....................

I get this on a postback of a page with user control which has some custom
controls on it.

I'm working in ASP.NET 1.1 (VS 2003)
Any suggestions will be appriciated

When creating the child-controls of the custom control, you need to
add them with unique IDs. So, simply assign an ID!
