Using Ajax can I set page properties, meaning for eg.
I have this ListEditMap of items(defined as a Page Property) in my
cart which are displayed in the page using @ListEdit component. I am
trying to add a Ajax help. wherin the user is typing in the name and
the available items are pulled from DB using AJAX. But now when a item
is selected. I have to add it to this ListEditMap for items. There are
2 steps for this. FIRST, I have to identify the selected item and
SECOND, add it to the pages' ListEditMap. For the first one ur earlier
reply should be the solution. Still stuck with the second one though.
Can this be done or am I going wrong somewhere. I want this to happen
without a page refresh. Is that possible?
