What you have you done paste it. so that anyone can help you to sort the problem. Don't just ask I need solution? try and show what you have done and I'm sure everyone will try to help you to sort the problem.

try these snippet in your code

DataView dv = dt.DefaultView;
dv.Sort = "columnname desc";
DataTable dts = dv.ToTable();

Or better, don't put strings into your data when you want numbers: use numeric fields instead. They sort correctly and normally.

1. Create a clone of the data in the above table that you have.
2. Specify the Data Type in clone table, for the sort column as needed. Eg. System.Decimal for decimal column.
3. Import each row from original table to clone table.
4. Commit the changes in clone table.
5. Create a DataView on clone table.
6. Specify the sort column and sort order for the DataView.
7. Bind DataView to GridView.

C#

DataTable dtMarks1 = dtMarks.Clone();
            dtMarks1.Columns["Total"].DataType = Type.GetType("System.Decimal");

            foreach (DataRow dr in dtMarks.Rows)
            {
                dtMarks1.ImportRow(dr);
            }
            dtMarks1.AcceptChanges();


            DataView dv = dtMarks1.DefaultView;
            dv.Sort = "Total DESC";

            GridView1.DataSource = dv;
            GridView1.DataBind();
