Variable value not updating dataset

If I put a text value in the variable it posts, if I get it from the field it does not. It does not bomb out, it just does not pass the test

If Not mydataset.HasChanges(DataRowState.Modified) Then Exit Sub

weird?



Code:

Dim vUser As String
Dim vDist As String
Dim vCarrier As String
Dim Ret As Integer

Try

vUser = TextBox2.Text
vDist = TextBox3.Text
vCarrier = TextBox4.Text
MsgBox(vUser)

mydataset.Tables("tblcarrier").Rows(0).Item("Name") = vUser

If Not mydataset.HasChanges(DataRowState.Modified) Then Exit Sub

Dim xDataSet As DataSet
MsgBox("made it2")
' GetChanges for modified rows only.
xDataSet = mydataset.GetChanges(DataRowState.Modified)
' Check the DataSet for errors.
If xDataSet.HasErrors Then
' Insert code to resolve errors.
End If
MsgBox("made it3")
adpCarriers.Update(xDataSet, "tblcarrier")
MsgBox("Made it4")

Catch ex As Exception
System.Diagnostics.Debug.WriteLine(ex.Message & "l " & ex.StackTrace)


'Finally
conn.Close()
End Try
