asp.net mvc - How to use ViewBag to pass list of data from View to controller -

how can sen list of items view controller save it. believe can use viewbag dont realy no how use ite pass data view controller.

this have tried view

@using (html.beginform()) { @html.validationsummary(true) <fieldset>     <legend>productionorderitem</legend>       <div class="editor-label">         @html.label("producrionorderno");     </div>     <div class="editor-field">         @html.textbox("productionorderno", viewbag.productionorder int)      </div>      <div class="editor-label">        @html.label("ordername")     </div>     <div class="editor-field">         @html.textbox("ordername", viewbag.productionorder string)     </div>  <div class="editor-label">        @html.label("orderdate")     </div>     <div class="editor-field">         @html.textbox("orderdate", viewbag.productionorder datetime) </div>       <p>         <input type="submit" value="create" />     </p> </fieldset> } 

and controller

   [httppost]      public actionresult create(formcollection collection)      {         productionregistration pr = new productionregistration();         productionitem poi = new productionitem();           poi = viewbag.productionorder;           pr.saveorder(conn, poi);          return redirecttoaction("index");       } 

you can't pass data viewbag/viewdata to controller. it's one-way (controller view). way data controller post (post-body) or send along in querystring.

in fact, should avoid viewbag as possible. added convenience , convenience methods, it's abused more not. use view model both pass data view , accept data post.

you strongly-type view with:

@model namespace.for.my.orderviewmodel 

then, can use [foo]for methods of razor build fields in strongly-typed way:

<div class="editor-label">     @html.labelfor(m => m.productionorderno); </div> <div class="editor-field">     @html.textboxfor(m => m.productionorderno) </div> 

and in post action, accept view model param:

[httppost] public actionresult create(orderviewmodel model) {     ... } 

and let mvc's modelbinder wire posted data you.

no more dynamics. strongly-typed end-to-end, if goes wrong, you'll know @ compile-time, not run-time.
