Comparing Tables in a Selector

Well, I do apologize for the lapse. I get so involved that I overlooked this.
I have come up with a solution to compare two tables when displaying one in the selector.
I defined a procedure just like the ShowUserButton to compare tables:

    public bool CompareTables
    {
        set
        {
            HttpContext.Current.Session[UniqueName + "CompareTables"] = value;
            if (value)
            {
                ux_UserResults.Visible = true;
                FillResultsByCompareTables();  //add the results that belong to the user to the gridview
            }

        }
        get
        {
            if (HttpContext.Current.Session[UniqueName + "CompareTables"] == null)
                HttpContext.Current.Session[UniqueName + "CompareTables"] = false;  //default to false
            return (bool)HttpContext.Current.Session[UniqueName + "CompareTables"];
        }
    }

When true, it calls the procedure FillResultsByCompareTables(). Just like ShowUserButton, I call this by setting CompareTables to true:

MainSelector.CompareTables = true;          // I made this to compare two tables and display the results in the selector - Briscoe 05.27.08
