Web services do not have a "web context", that is created when a person goes to a url that maps to a portal and the person logs in, so you do not have a "logged in user".

Design is the craft of visualising concrete solutions that serve human needs and goals within certain contraints. Visulising concrete solutions is the essence of design.

Hi Chad

 You can also use code belove to load user control with additional parameters:

/// <summary>
/// Loads user control with parameters
/// </summary>
private Control LoadControl(string userControlPath, params object[] constructorParameters) {
            List<Type> constParamTypes = new List<Type>();

            for (int i = 0; i < constructorParameters.Length; i++)
                constParamTypes.Add(constructorParameters[i].GetType());

            Control ctl = Page.LoadControl(userControlPath);
            ConstructorInfo constructor = ctl.GetType().BaseType.GetConstructor(constParamTypes.ToArray());
            if (constructor == null)
                throw new MemberAccessException("The requested constructor was not found on : " + ctl.GetType().BaseType.ToString());
            else
                constructor.Invoke(ctl, constructorParameters);
            return ctl;
}

 //to execute method above

this.LoadControl(this.ControlPath + @"/Controls/MyCustomControl.ascx", this.UserID)
