add text box in grid view

I want change the content in grid view to textbox.
Here is part of my code 

public class TextBoxTemplate : ITemplate
{
    public void InstantiateIn(Control container)
    {
        TextBox txtBox = new TextBox();
        txtBox.ID = "txtBox";

        container.Controls.Add(txtBox);
    }
}

//dtTeaching is data sourse for grid view 

foreach (DataColumn col in dtTeaching.Columns)
{       
   if (col.ColumnName.Contains("Name"))
   {
       TemplateField tfName = new TemplateField();
       tfName.ItemTemplate = new TextBoxTemplate();
       tfName.HeaderText = "Programme Name";
       gvTeaching.Columns.Add(tfName);
   }
 }

 gvTeaching.DataSource = dtTeaching;
 gvTeaching.DataBind();


 for (int i = 0; i < gvTeaching.Rows.Count; i++)
 {
     TextBox k = (TextBox)gvTeaching.Rows[i].Cells[0].Controls[0];
     k.Text = "test";
 }

But the result is nothing will display in the grid view.
No textbox no content, just 3 blank rows,

Can you take: 

TemplateField tfName = new TemplateField();
tfName.EditTemplate = new TextBoxTemplate();
tfName.HeaderText = "Programme Name";
gvTeaching.Columns.Add(tfName);

You can try to add EditTemplate for editing the value in GridView.

Or You can simply add those fields on GridView.
Like:
......

<Columns>
   <asp:TemplateField>
      <ItemTemplate>
         <asp:Label ID="lbl" runat="server" Text='<%#Bind("ColumnName") %>' />
      </ItemTemplate>
      <EditTemplate>
         <asp:TextBox ID="txt" runat="server" Text='<%#Bind("ColumnName")%>' />
      </EditTemplate>
   </asp:TemplateField>
</Columns>

When the grid will be displayed on the page data will be placed in Label and when you edit that row it will be displayed in TextBox.

Why don't you use Template field.
At design time why at run-time?

Here is a example of template field

<asp:TemplateField HeaderText="FirstName" SortExpression="FirstName">
  <EditItemTemplate>
    <asp:TextBox ID="TextBox1" runat="server"
        Text='<%# Bind("FirstName") %>'></asp:TextBox>
  </EditItemTemplate>
  <ItemTemplate>
    <asp:Label ID="Label1" runat="server"
        Text='<%# Bind("FirstName") %>'></asp:Label>
    <asp:Label ID="Label2" runat="server"
        Text='<%# Bind("LastName") %>'></asp:Label>
  </ItemTemplate>
 </asp:TemplateField>
