I'm trying to add the IsPublished field for a variant on the EntityProductVariantsOverview page (between DisplayOrder and IsDefault)

I've added the fields as other fields displayed on the code page, and I've added an
<asp:Literal ID="ltIsPublished" runat="server"></asp:Literal>.

It doesn't error, but it doesn't display. I've tried ltPublished as well.

Is IsPublished just simply not available via e.Row.FindControl?

Any thoughts? I'd like to be able to see which variants are published without having to go through each one.
