Textbox control at runtime

I have created a textbox control at runtime and have populated it with some data. The first time the event button is click the data is populated fine. The second time through the data is not getting updated. I have debuged the program and the actual textbox does have the updateded data in it but it is like its not refreshing on the form. Here is the code:

Dim cadd1 As New TextBox()
If DataSet11.MSCMP100(0).CADD1 <> "" Then

cadd1.Text = DataSet11.MSCMP100(0).CADD1
cadd1.Location = New Point(104, 130)
cadd1.Multiline = True
cadd1.Size = New Size(344, 100)
cadd1.BorderStyle = BorderStyle.None
cadd1.Font = New System.Drawing.Font("Arial", 12, FontStyle.Bold)

End If

'if any address lines are blank then skip
If DataSet11.MSCMP100(0).CADD2 <> "" Then
cadd1.Text = cadd1.Text & vbCrLf & DataSet11.MSCMP100(0).CADD2
End If
If DataSet11.MSCMP100(0).CADDX <> "" Then
cadd1.Text = cadd1.Text & vbCrLf & DataSet11.MSCMP100(0).CADDX
End If

'add city, state and zip
cadd1.Text = cadd1.Text & vbCrLf & DataSet11.MSCMP100(0).CADD3 & "," & _
" " & DataSet11.MSCMP100(0).CSTTE & " " & DataSet11.MSCMP100(0).CZIPC

Controls.Add(cadd1)

cadd1.Visible = True
