Problem Accessing Dynamically Created Control

Hi All,
I have some Problem Accessing dynamically created controls. Actually what I have to do is
I have to get different set of questiond based on the order type.
For example , OrderType A may have 5 questions . It can be a short text, Long Text or a multiple choice question and
OrderType B may have 3 questions of different Type.
I have to create different control(textbox, multi line textbox, radioButton) based on the que type.
I am adding all the controls to a table and the table to a placeholder.
I don't have any problem creating the questions and controls dynamically.
But the problem bubble up when i try to access the dynamically created control.
I am creating the control in the Page_Init
and I am trying to get the response from those dynamically created control once the user click on the submit button.
Here is the code:
PrivateSub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) HandlesMyBase.Init
Dim mytable AsNew Table
Dim que As DataTable
Dim qrow As DataRow
Dim row AsInteger
IfNot IsPostBack Then
Dim myorderid = CInt(1)
Dim myaccount As DNS.OrdersDB = New DNS.OrdersDB
myserviceid = myaccount.GetServiceType(myorderid)
que = New DataTable
que = DNS.QADB.GetQuestions(myserviceid).Tables(0)
row = CInt(que.Rows.Count)
Dim i AsInteger
For i = 0 To row - 1
qrow = que.Rows(i)
Dim mytype AsString = qrow("QueType")
Dim myreq AsString = qrow("QueRequired")
If mytype = "SHORT TEXT" Then
Dim myrow AsNew TableRow
Dim myrow1 AsNew TableRow
Dim mycell AsNew TableCell
Dim mycell1 AsNew TableCell
Dim lbl As Label = New Label
lbl.Text = qrow("QueName")
Dim mylblid AsString = "lbl" + CStr(qrow("Queid"))
lbl.ID = mylblid
Dim txt As TextBox = New TextBox
txt.ID = qrow("Queid").ToString()
txt.Width = Unit.Pixel(Convert.ToInt32(200).ToString())
mycell.Controls.Add(lbl)
mycell1.Controls.Add(txt)
myrow.Cells.Add(mycell)
myrow1.Cells.Add(mycell1)
mytable.Rows.Add(myrow)
mytable.Rows.Add(myrow1)
ElseIf (mytype = "LONG TEXT") Then
' as added above
End If
Next
myplace.Controls.Add(mytable)
EndIf
EndSub

Private Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
Dim mytable As New Table
Dim que As DataTable
Dim qrow As DataRow
Dim row As Integer
Dim myorderid = CInt(1)
Dim myaccount As DNS.OrdersDB = New DNS.OrdersDB
myserviceid = myaccount.GetServiceType(myorderid)
que = New DataTable
que = DNS.QADB.GetQuestions(myserviceid).Tables(0)
row = CInt(que.Rows.Count)
Dim i As Integer
For i = 0 To row - 1
qrow = que.Rows(i)
Dim mytype As String = qrow("QueType")
Dim myreq As String = qrow("QueRequired")
If mytype = "SHORT TEXT" Or mytype = "LONG TEXT" Then
' Trying to get the value of the textbox
Dim c As TextBox = Page.FindControl(qrow("QueId"))
Dim myresponse As String = c.Text
If myreq = "YES" And myresponse = "" Then
lblerr.Text = qrow("QueName")
lblerr.Visible = True
Else
Dim mysystem As DNS.QADB = New DNS.QADB
Dim mystsring As String = mysystem.addQAResponse(qrow("QueId"), myresponse)
End If
End If
Next
End Sub
It's really very urgent. Please someone help me with this. Any Help is greatly appreciated
