Can't get value from TextBox in GridView

Hiya
I have a GridView on an ASP.NET page with a TemplateField column that has a TextBox in the ItemTemplate. I then have a command field which is supposed to pull the text from this TextBox and use it in a SqlCommand running a stored procedure. The code is being from the OnRowCommand event from the gridview.

Here is my C# code:

Code:

int index = Convert.ToInt32(e.CommandArgument);    
GridViewRow selectedRow = this.gvwSNConfirm.Rows[index];    
TableCell intID = selectedRow.Cells[1];    
int reqID = int.Parse(intID.Text);    </SPAN>
// Get the SN from the text box on the selected row    </SPAN>
TableCell snCell = selectedRow.Cells[0];    
TextBox tbox = (TextBox)snCell.FindControl("txtSN");    
string stSN = tbox.Text.ToString(); <--the bit that doesnt work

I have no idea why this wont work. It is the same as another web form with the exception of the control names.

Can anyone point me in the right direction?

Thanks

I deleted and re-created the form but changing the code slightly and it seemed to do the trick.
The code was changed to:

Code:

 
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow row = gvwSecond.Rows[index];
int secondID = int.Parse(row.Cells[1].Text);
TextBox txtsn = ((TextBox)row.FindControl("txtSecSN")); 
string sn = txtsn.Text;

I'm not sure if tehre was anything lingering in the design classes which I didnt see which was stopping the value being picked up but it is working now
