If I understand correctly you have two buttons and a textbox. Button1 displays the text displayed on Button1 in the TextBox and then Button2 stores the content of the textbox in the DB (somehow) then disables button1. If so, try this:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    TextBox1.Text = Button1.Text
End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
    Dim DBValue As String = TextBox1.Text
    'Store DBValue in DB
    Button1.Enabled = False
End Sub

If you have multiple buttons and want to find which button was pressed based on the value in textbox1, try this:

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
    For Each ctrl As Control In Me.Controls
        If (ctrl.GetType() Is GetType(Button)) Then
            Dim btn As Button = ctrl
            If btn.Text = TextBox1.Text Then
                DBValue = TextBox1.Text
                'Store DBValue in DB
                btn.Enabled = False
                Exit For
            End If
        End If
    Next
End Sub
