Error Fetching Custom Attribute Value from HtmlSelect

Tech-Archive recommends: Speed Up your PC by fixing your registry

I'm using an HtmlSelect (runat=sever).

I add the items programmatically and I also add a custom attribute to
each listitem because I need to track an additional field value.

I'm having a problem getting that attribute value upon postback. I keep
getting a null reference error. I was under the impression that the
attribute collection is saved in viewstate.

My code to get the attribute value is:

string val=
mySelect.Attributes["attrname"][mySelect.SelectedIndex].ToString();

What am I doing wrong?

Thanks.
