Reload viewstack child

Question

I am developing a flex application which has a master detail pages. The master page has a list of items in a datagrid and when the user clicks on an item the viewstack child is switched to display the details. I am also using a link bar to navigate back to the master view. However when the user clicks on a different item the child page does not get refreshed.
What is the best way to reload the child view when the user clicks on a datagrid item?

Answer 1

The easiest way is to have a bindable property in your detail View like:
[Bindable]
var user:UserType;
and to bind all of your components to that user object, fe:
<mx:Label id="userName" text="{user.name}" />
And in your ViewStack:
<mx:ViewStack>
     <SomeContainer>
          <mx:DataGrid id="yourDataGrid" ... />
     </SomeContainer>
      <UserDetailView user="{yourDataGrid.selectedItem}"
</mx:ViewStack>
After changing the selection in your dataGrid, a new user object will be automatically binded to the view component.
Of course you may consider a more complex solution with building a model layer containg selectedUser property, but the solution above should work ok.
