jquery - How to validate data requiring a look "up the object graph"? -


i'm hoping there's easy way via asp.net mvc built-in support validation attributes, haven't been able see far.

notes:

  1. we using:

    • mvc3
    • jquery unobtrusive validation
    • twitter bootstrap "wizard" tabs

  2. the wizard works via ajax - not submitting form each step of way.

here code inherited (slightly changed protect innocent):

here basic view model(s) (note not public variables - auto-properties condensed space):

class transactionviewmodel {         public reasonviewmodel reason; /* in tab, user selects reasons change */         public customerviewmodel customer; /* details customer user can edit */         public surveyviewmodel survey; /* survey wizard experience user can fill out */                                        /* (also, "the wizard experience", new band name, call it.) */     }

here view inherited

<div class="tab-pane" id="reason">    @html.editorfor(m => m.reason, "reasonviewmodel") </div>  <div class="tab-pane" id="reason">    @html.editorfor(m => m.customer, "customerviewmodel") </div>  <div class="tab-pane" id="reason">    @html.editorfor(m => m.survey, "surveyviewmodel") </div>

and here problem:

**we need implement validation such when user enters reason of "add customer", customer.dateofbirth property cannot set date in future. purposes of example, want validation occur on particular reason - other reasons leave alone. **

my question is: if put validator on customer.dateofbirth, how can move 'up chain' transaction.reason in order find out if need reject date or not?

i suppose wish this:

class transactionviewmodel {         /* ... */         [addmembercanthavefuturebirthdate]         public reasonviewmodel reason; /* in tab, user selects reasons change */        /* ... */     }

but can't seem validation work @ level.

has run type of thing before? if so, how did solve it?
