i want to create rows in gridview base on point,and display name of point in the text box.what i so far tried is as follow

DataTable dt = new DataTable();

        DataRow dr = null;

       
        var SecPoint = _service.GetAllDutyPoint().ToList();
        foreach (var point in SecPoint)
        {
            for (int I = 1; I <= point.NoOfMinEmployes; I++)
            {
                ////Define the Columns
                //dr["RowNumber"] = I + 1;
                //dt.Columns.Add(new DataColumn("RowNumber", typeof(string)));

                //dt.Columns.Add(new DataColumn("Column1", typeof(string)));

                //dt.Columns.Add(new DataColumn("Column2", typeof(string)));

                //dt.Columns.Add(new DataColumn("Column3", typeof(string)));

                //dr = dt.NewRow();

                

                //dt.Rows.Add(dr);
                ////Store the DataTable in ViewState

                //ViewState["CurrentTable"] = dt;

                ////Bind the DataTable to the Grid

                //Gridview1.DataSource = dt;

                //Gridview1.DataBind();
                ////Extract and Fill the DropDownList with Data
                //TextBox txtbox = (TextBox)Gridview1.Rows[0].Cells[1].FindControl("TextBox12");
                //DropDownList ddl1 = (DropDownList)Gridview1.Rows[0].Cells[2].FindControl("ddlEmp");
                //TextBox txtbox1 = (TextBox)Gridview1.Rows[0].Cells[3].FindControl("TextBox13");
                //DropDownList ddl2 = (DropDownList)Gridview1.Rows[0].Cells[4].FindControl("ddlEmp2");
                //FillDropDownList(ddl1);
                //FillDropDownList(ddl2);

 private void FillDropDownList(DropDownList ddl)
    {

        
        var emp1 = _service.GetEmployeeDutyByEmployee_Id(MyUser.Employee_Id).LastOrDefault();
        var EmpList = _service.GetAllEmployeeDuty().OrderByDescending(x => x.EndDate).GroupBy(x => x.Employee_Id).Select(x => x.First()).ToList();
        var empList = EmpList.Where(X=>X.ToSector_Id== emp1.ToSector_Id).ToList();
        ddl.Bind(empList, "EmployeeIdName", "Employee_Id");
    }   
    }

its just return one row
