The OnClick method of the Button calls an EventHandler...try to modify your
code like so (i got rid of the style stuff just to help readability, you can
safely put it in)

<asp:button id="btnSave" runat="server" CommandArgument="'The information
has been added to the database" onclick="save_click" Text="Save" />

and the method:

   Protected Sub Save_Click(ByVal sender As Object, ByVal e As EventArgs)
      DisplayAlert(CType(sender, Button).CommandArgument)
   End Sub
