I have a collection of CLR objects. The class definition for the object has three properties: FirstName, LastName, BirthDate.

I have a string that reflects the name

protected void sort_grd(object sender, GridViewSortEventArgs e)
    {
        if (Convert.ToBoolean(ViewState["order"]) == true)
        {
            ViewState["order"] = false;

        }
        else
        {
            ViewState["order"] = true;
        }
        ViewState["SortExp"] = e.SortExpression;
        dataBind(Convert.ToBoolean(ViewState["order"]), e.SortExpression);
    }

public void dataBind(bool ord, string SortExp)
    {
        var db = new DataClasses1DataContext(); //linq to sql class
        var Name = from Ban in db.tbl_Names.AsEnumerable()
                         select new
                         {
                             First_Name = Ban.Banner_Name,
                             Last_Name = Ban.Banner_Project
                         };
        if (ord)
        {
            Name = BannerName.OrderBy(q => q.GetType().GetProperty(SortExp).GetValue(q, null));
        }
        else
        {
            Name = BannerName.OrderByDescending(q => q.GetType().GetProperty(SortExp).GetValue(q, null));
        }
        grdSelectColumn.DataSource = Name ;
        grdSelectColumn.DataBind();
    }
