                      string Qtval1 = qtval[1].Substring(0, qtval[1].Length - 1);

                      //  e.DisplayText = qtyvalue123;
                  }
                //  e.DisplayText = Qtval1 + "and " + qtval[i];
                  //  e.DisplayText = "test1";
              }

Forget about gridview! Keep focus on data! What is the source of gridview: datatable, dataset, ...?

Please, read my comment to the question first. As i mentioned, you have to keep your focus on data, not gridview object.

On the first look you have 2 ways to achieve that:
#1
Split data on server side by using CTE[^] or custom function[^].
split string from database column and display in gridview[^]
get 2nd and 3rd string by splitting a long string using T-Sql[^]

#2
Split data on client side by using dataset (datatable) and Linq
LINQ Tutorial - Linq to strings with examples.[^]

Take a look at example:

C#

DataTable dt = new DataTable();

dt.Columns.Add(new DataColumn("No", typeof(int)));
dt.Columns.Add(new DataColumn("Code", typeof(string)));
dt.Columns.Add(new DataColumn("qty", typeof(string)));
dt.Rows.Add(new object[]{1055, "956,957,958,959", "10,9,5,4"});

var result = dt.AsEnumerable()
	.Select(x=>new
		{
			No = x.Field<int>("No"),
			Codes = x.Field<string>("Code")
				.Split(new string[]{","}, StringSplitOptions.RemoveEmptyEntries)
				.Select((a, b) => new
					{
						Index = b,
						Code = a
					}),
			Qty = x.Field<string>("qty")
		})
	.Select(x=>new
		{
			No = x.No,
			Code1 = x.Codes.Where(y=>y.Index==0).Select(z=>z.Code).SingleOrDefault(),
			Code2 = x.Codes.Where(y=>y.Index==1).Select(z=>z.Code).SingleOrDefault(),
			Code3 = x.Codes.Where(y=>y.Index==2).Select(z=>z.Code).SingleOrDefault(),
			Code4 = x.Codes.Where(y=>y.Index==3).Select(z=>z.Code).SingleOrDefault(),
			Qty = x.Qty
		})
	.ToList();
		
	result.Dump();

As you see, static headers have been used in above code.
