This is the code I use for autogrow.

1. $(document).ready(function(){
2.             $('.expanding').autogrow();
3.         });

1. <asp:TextBox ID="txtNotes" runat="server" CssClass="expanding" Text='<%# Bind("notes") %>' TextMode="MultiLine" Width="96%" />

1. .expanding
2. {
3.     line-height: 20px;
4.     width: 400px;
5. }

The problem is after RadioButtonList control autopostback happened, the autogrow no longer works. Any suggestion?
