once go through this code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;

namespace WebApplication1
{
    public partial class WebForm1 : System.Web.UI.Page
    {
            GridView GrdDynamic=new GridView ();
        protected void Page_Load(object sender, EventArgs e)
         {
            loadDynamicGrid();
           panelname.Controls.Add(GrdDynamic);
         }

    private void loadDynamicGrid()
    {
       
        #region Code for preparing the DataTable

        //Create an instance of DataTable
        DataTable dt = new DataTable();

        //Create an ID column for adding to the Datatable
        DataColumn dcol = new DataColumn(ID ,typeof(System.Int32));
        dcol.AutoIncrement = true;
        dt.Columns.Add(dcol);

        //Create an ID column for adding to the Datatable
        dcol = new DataColumn("NAME", typeof(System.String));
        dt.Columns.Add(dcol);

        //Now add data for dynamic columns
        //As the first column is auto-increment, we do not have to add any thing.
        //Let's add some data to the second column.
        for (int nIndex = 0; nIndex < 10; nIndex++)
        {
            //Create a new row
            DataRow drow = dt.NewRow();

            //Initialize the row data.
            drow["NAME"] = "Row-" + Convert.ToString((nIndex + 1));

            //Add the row to the datatable.
            dt.Rows.Add(drow);
        }
        #endregion

        //Iterate through the columns of the datatable to set the data bound field dynamically.
        foreach (DataColumn col in dt.Columns)
        {
            //Declare the bound field and allocate memory for the bound field.
            BoundField bfield = new BoundField();

            //Initalize the DataField value.
            bfield.DataField = col.ColumnName;

            //Initialize the HeaderText field value.
            bfield.HeaderText = col.ColumnName;

            //Add the newly created bound field to the GridView.
            GrdDynamic.Columns.Add(bfield);
        }

        //Initialize the DataSource
        GrdDynamic.DataSource = dt;

        //Bind the datatable with the GridView.
        GrdDynamic.DataBind();
    }
    }
}

write this in aspx page

 <body>
    <form id="form1" runat="server">
 
    <div id="testgrid"  runat="server">
        <asp:panel runat="server" id="pnael34" xmlns:asp="#unknown">
        </asp:panel>
    </div>
    </form>
</body>
