ASP.NET viewstate support for custom web server controls
<p>I am not able to understand the following : (It is related to adding viewstate support when creating custom web server controls)</p>

<p>"However, if these properties need to be manipulated inside code, you
might want to provide ViewState support to ensure a consistent developer experience
similar to that of other ASP.NET controls. This will ensure that the properties set inside
server code are not suddenly switched back to markup values after a postback."</p>

<p>Can someone please elaborate ?</p>

<p>Thanks.</p>
