Answer 1

this is a part of the code that i had to write to do it :

if (emord.Text == "Ascending")
        {

            if (emsort.Text == "ID")
            {
                var empName = el.Select(i => new { i.ID, i.FullName }).OrderBy(x => x.ID);
                var empNamenAmp = el.Select(i => new { i.ID, i.FullName, i.Salary, i.Currency, i.Per }).OrderBy(x => x.ID);
                var empNamenAmpnwh = el.Select(i => new { i.ID, i.FullName, i.Salary, i.Currency, i.Per, i.Hours }).OrderBy(x => x.ID);
                var empNamenwh = el.Select(i => new { i.ID, i.FullName, i.Hours }).OrderBy(x => x.ID);
                var empNamenbd = el.Select(i => new { i.ID, i.FullName, i.Date }).OrderBy(x => x.ID);
                var empNamenad = el.Select(i => new { i.ID, i.FullName, i.Location }).OrderBy(x => x.ID);
                var empNamenpn = el.Select(i => new { i.ID, i.FullName, i.PhoneNb }).OrderBy(x => x.ID);
                var empNamena = el.Select(i => new { i.ID, i.FullName, i.Age }).OrderBy(x => x.ID);
                if (empfilcomb.Text == "Name")
                {
                    dispfil.Clear();
                    foreach (var x in empName)
                        dispfil.Text += x.ID + ", " + x.FullName + Environment.NewLine;
                }
                else if (empfilcomb.Text == "Name and Amount paid")
                {
