How to dynamically create columns in a datagridview and assign titles to it and its rows?

Assume that your results from database is put on list, and each row of results is put on Student class.

IList<student> listStudent</student>

Assume that Student class is below:

public class Student {
  public string StudentID {set; get;}
  public string StudentName {set; get;}
}

In aspx file, put tag gridview, see the below for example:

<asp:gridview runat="server" id="gvStudent" autogeneratecolumns="False" xmlns:asp="#unknown">
  AllowPaging="True" AllowSorting="False" EmptyDataText="No Data Found"
  HorizontalAlign="Center" Width="100%" DataKeyNames="StudentID " PageSize="20">

  <emptydatarowstyle horizontalalign="Center" verticalalign="Middle" width="100%" />
  <columns>
    <asp:templatefield headertext="No.">
      <headerstyle width="5%"></headerstyle>
      <itemtemplate>
        <asp:label id="Label2" runat="server" name="No" text="<%# (gvStudent.PageIndex * gvStudent.PageSize) + gvStudent.Rows.Count + 1 %>">
        </asp:label>
      </itemtemplate>
      <itemstyle horizontalalign="Center" />
    </asp:templatefield>
    <asp:boundfield headertext="Student ID" datafield="StudentID" />
    <asp:boundfield headertext="Student Name" datafield="StudentName" />
  </columns>
</asp:gridview>

And in code behind, see the below for the example:

private void BindGridView()
{
  //Retrieve student from database, and put on list
  IList<student> listStudent = ......

  //Bind Result to GridView
  this.gvStudent.DataSource = listStudent;
  this.gvStudent.DataBind();
}
</student>

And call method BindGrindView on button click
