Show all items in edit mode in RadGrid and save all changes by clicking on submit

I need to realize a WebSite with a grid that shows all items of my Collection in edit mode like this:

On Apply the edited Collection should be saved. On changing selection in the Supplier combobox shoud show the appropriated logo below. (Is it possible to realise it using a binding instead of unbound code-behind implementation?)

How to implement it with RadGrid? Is any 开发者_如何学Csimplier as RadGrid solution in ASP.Net 4.0 with WebForms?

1. Regarding the logo from down, try a customised radcombobox showing tex with Icons
2. I myself am looking for a way to configure and not code the update on 'Apply'
