[1.0] Binding ext:GridCommand.Disabled to a record field

Hi,

Sorry if this is a repost. I definitely posted this before, but it seems that post is gone! Odd.

I'm using Ext.NET 1.0 and I'm using the extnet-mvc project as a example base for my project.

If you look at CustomerList.aspx you'll see a ext:GridPanel with each row having a delete ext:GridCommand.

I want to do something similar but have the delete button enable / disabled depending on a field in the record.

How can I do this?

Thanks,
Francois
