Default Update Statement some error

hi,

following is the code for editing.The problem is in the Onclick of edit button.The values are not getting updated.I tried updating the
textbox1's value.and i tried printing too.But its not working.
The output is the following.Say i am inputing value 20 in the
textbox1.But the value 20 doesnt get passed in the update statement.

UPDATE TEACHERS SET TNAME='' where TID ='5689'
'This is the UPDATE statement.
strSQL = "UPDATE TEACHERS SET TNAME='"& TextBox1.Text &"' where TID ='"& str &"' "

<html>
<script language="vb" runat="server">
Sub Page_Load
dim cv as string
dim username as string
dim email as string
dim sname as string
dim str as string

Dim strConnection As String = "user id=sa;password=admin;server=.;initial catalog=students"
Dim cn As SqlConnection = New SqlConnection(strConnection)
cn.Open()

str = (request.querystring("cv"))
Dim strSelect As String = _
        "SELECT * FROM teachers"
Dim cmd As SqlCommand = New SqlCommand(strSelect, cn)
Dim dr As SqlDataReader
dr = cmd.ExecuteReader()
while dr.Read
if str=dr("TID") then
TextBox1.Text = dr("TNAME")
TextBox2.text=dr("DESIGNATION")
TextBox3.text=dr("CONTACTNO")
TextBox4.text=dr("EMAIL")
TextBox5.text=dr("USERNAME")
TextBox6.text=dr("PWD")
end if
end while
cmd.dispose()
cn.close()
end sub

Sub edit(s As Object, e As EventArgs)
dim str as string
dim cv as string
dim p as string
Dim conClasf As SqlConnection
Dim dbstring As String
Dim strSQL As String
dim tid as string
str = (request.querystring("cv"))
lblRecsAff.Text = "hi"
response.write(lblRecsAff.text)
lblRecsAff.Text = ""
dbstring = "user id=sa;password=admin;server=.;initial catalog=students"
conClasf = New SqlConnection(dbstring)
conClasf.open()
strSQL = "UPDATE TEACHERS SET TNAME='"& TextBox1.Text &"' where TID ='"& str &"' "
response.Write(strsql)
Dim cmd As New SqlCommand(strSQL,conClasf)
cmd.ExecuteNonQuery()
