DataEnvironment and textbox

I´ve a problem with text box linked with a command. When I redo a query this control does not refresh. Recordset is updated but the control does not reflect this. Even using refresh method of textbox or updating DataMember property it not refresh.

I Can do the same operation using DataControl(ADO), but I think that DataEnvorironment uses just I connection on my case, using DataControl I´ll need a Connection to each one of them.

Someone knows how can I do this with DataEnvironment?

Thank you.
