In winform That is more easy. like declare Mytable globally and use blow

if (dataGridView1.RowCount == 0)
           {
               MyTable = new DataTable();
               DataColumn values = new DataColumn("slno");
               DataColumn values1 = new DataColumn("startno");
               DataColumn values2 = new DataColumn("noc");
               DataColumn values3 = new DataColumn("endno");

               MyTable.Columns.Add(values);
               MyTable.Columns.Add(values1);
               MyTable.Columns.Add(values2);
               MyTable.Columns.Add(values3);
           }


               DataRow rd = MyTable.NewRow();
               rd[0] = textBox1.Text;

           rd[1] = textBox2.Text;

           rd[2] = textBox3.Text;
           rd[3] = textBox4.Text;


           dataGridView1.DataSource = MyTable;
           dataGridView1.Sort(dataGridView1.Columns["slno"], ListSortDirection.Descending);

Use Below code in button click

DataTable MyTable = (DataTable)ViewState["Dt"];
            if(MyTable== null)
            {
                MyTable = new DataTable();
                DataColumn values = new DataColumn("slno");
                DataColumn values1 = new DataColumn("startno");
                DataColumn values2 = new DataColumn("noc");
                DataColumn values3 = new DataColumn("endno");

                MyTable.Columns.Add(values);
                MyTable.Columns.Add(values1);
                MyTable.Columns.Add(values2);
                MyTable.Columns.Add(values3);
            }
            
            DataRow rd = MyTable.NewRow();
            rd[0] = textBox1.Text;

            rd[1] = textBox2.Text;

            rd[2] = textBox3.Text;
            rd[3] = textBox4.Text;


            MyTable.Rows.Add(rd);
            ViewState["Dt"] = MyTable;
            dataGridView1.DataSource = MyTable;
            dataGridView1.DataBind();
