Do you have a SelectedIndexChanged or SelectedValueChanged EventHandler? These events fire many times when a control is first instantiated. Typically what I do is to not DataBind and not set up the delegates for the eventhandlers until the Form load instead of in the Form's init. (This means having to do it manually in code instead of in the Property Sheet).
