vb.net get an only one datatable row value cell and compare it with a textbox
<p>How to get a only one datatable row cell value ? i need to comparison it with a textbox.
Like this:</p>

<pre><code>If dttest.Rows.Count &lt; 2 Then
                For counter As Integer = 0 To dttest.Rows.Count - 1
                    If TextBox1.Text = MyDataTable.Rows(1).RowName ' but doesn't accept this format
                        Process.Start("http:\\www.google.it")
                    End If
                Next
            End If
</code></pre>

<p><strong>UPDATE</strong> Full code:</p>

<pre><code>Public Class Form2
    Private dttest As DataTable
    Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged
        Dim dvtest As New DataView
        dvtest = dttest.DefaultView
        dvtest.RowFilter = "test Like '%" + TextBox1.Text + "%'"
    End Sub

    Private Sub Form2_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        ListBox1.DataSource = Getdata()
        ListBox1.DisplayMember = "test"
    End Sub

    Private Function Getdata() As Object
        dttest = New DataTable()
        dttest.Columns.Add("test", GetType(String))
        dttest.Rows.Add("test1")
        dttest.Rows.Add("test2")
        Return dttest
    End Function
End Class
</code></pre>

<p>How can i get a single row value, for example, the dttest.Rows.Add(<strong>"test1"</strong>) ?</p>
