Master/Detail and reusable content
Hello,
I'm trying to develop a litle framework based on ext.net.
<ul>[*]I've a MasterPage that is inherited for registers. Each subject has its inheritance.[*]Inside this MasterPage there is a UserControl used for Search wich its
grid columns and filter fields are built dynamically;[/list]
