ItemUpdating NewValues Missing Parameter

I have a formview with several data items that works perfectly except for a single parameter that will not update with the rest of them. The formview's datasource updateparameter is set to do nothing so that I can handle the update in codebehind. Every item works fine, except for one parameter ("salesprice") that is missing in the OldValues and NewValues argument of the ItemUpdating event of the formview. The data DOES pull in to the textbox as it should, formatted properly and all.

I've attached the html, SQL (for getLoanData()), and the codebehind.

Why would every parameter exist in the New/OldValue arguments except the "salesprice" parameter? I've tried populating the textbox without the formatstring, and it's still missing. Is there something about a money SQL datatype that might cause a problem?

Have you tried a different format string?

Text='<%# Bind("salesprice", "{0:C}") %>'
