How to set boundfield value to template field control?

enter image description here

I have gridview output like this .

when I click edit link, I need to pass unitsinstock value should transfer to textbox control. which is present in templatefield.

Here is my c# code:

TextBox tt = (TextBox)GridView1.Rows[i].Cells[3].FindControl("TextBox2").ToString();

TextBox text_ref = (TextBox)GridView1.Rows[e.NewEditIndex].Cells[2].FindControl("TextBox2");

TextBox3.Text = text_ref.Text;

Is there anything wrong? when I debugging e.NewEdtIndex=0, TextBox3=null. How to solve this?

You should use EditItemTemplate for this. For exemple, this code above will bound the unitsinstock value to unitsinstock copy text box when you edit the row.

Change The SqlDataSource as well:

<UpdateParameters>
    <asp:Parameter Name="unitsinstock" Type="Int32" /> /*Put the correcly type here*/
    /*other fields*/
</UpdateParameters>

And the GridView:

<asp:TemplateField HeaderText="unitsinstock">
  <ItemTemplate>
<asp:label id="labelUnitsinstock" runat="server" text='<%#Eval("unitsinstockActual")%>'>
    </asp:label>
  </ItemTemplate>
</asp:TemplateField>

<asp:TemplateField HeaderText="unitsinstock copy">
  <EditItemTemplate>
    <asp:TextBox ID="TextBox1" runat="server"
     Text='<%# Bind("unitsinstock") %>'></asp:TextBox>
  </EditItemTemplate>
</asp:TemplateField>
