c# - Passing part of a viewmodel to a controller -

i have customer index page takes customerindexviewmodel populate page list of customers, time request took, , many other pieces of information.

i have customersearchargsmodel inside customerindexviewmodel.

public class customerindexviewmodel : baseindexviewmodel {     public ienumerable<customer> customers{ get; set; }     public double requesttime { get; set; }     public customersearchargsmodel customersearchargsmodel { get; set; }     public othertypes othertype {get;set;} }   public class customersearchargsmodel {     public string customerid { get; set; }     public string firstname { get; set; }     public string lastname { get; set; } } 

on customer index page want have -

@model customerindexviewmodel  @{     viewbag.title = "index"; }  <h2>index</h2>  @using (html.beginform("index","customer",formmethod.post, new { id="searchsubmit"})) {     @html.labelfor(model => model.customersearchargsmodel.consumerid)     @html.editorfor(model => model.customersearchargsmodel.consumerid)     @html.labelfor(model => model.customersearchargsmodel.lastname)     @html.editorfor(model => model.customersearchargsmodel.lastname)     @html.labelfor(model => model.customersearchargsmodel.firstname)     @html.editorfor(model => model.customersearchargsmodel.firstname)      <input type="submit" value="search" /> } 

i want return typed in values index (post) method on customer controller in customersearchargsmodel.

but don't know how return model different 1 defined @ top of page.

you can put "searchsubmit" form inside partial view. pass model.customersearchargsmodel partial view. sure model.customersearchargsmodel not null; otherwise, exception.

index page

@html.partial("_search", model.customersearchargsmodel) 

_search partial view

@model customersearchargsmodel @using (html.beginform("index","customer",formmethod.post, new { id="searchsubmit"})) {     @html.labelfor(model => model.consumerid)     @html.editorfor(model => model.consumerid)     @html.labelfor(model => model.lastname)     @html.editorfor(model => model.lastname)     @html.labelfor(model => model.firstname)     @html.editorfor(model => model.firstname)      <input type="submit" value="search" /> } 

the problem approach 0 value displayed in textbox consumerid. solve problem can use html.action instead of html.partial.

hope helps.
