asp.net - MVC C# Session Project -

i posted question no 1 answered comments/errors had. how text entered in @html.textbox("searchstring") in index viw welcome view using session variables?

homecontroller.cs

using system; using system.collections.generic; using system.linq; using system.web; using system.web.mvc; using system.data.entity; using newproject.models;  namespace newproject.controllers {  public class homecontroller : controller   {     public actionresult index()     {         return view();     }     [httppost]     public actionresult gender(welcomevm model)      {         model.genders = new list<selectlistitem>    {      new selectlistitem { value="male", text="male"},      new selectlistitem { value="female", text="female"}     };         return view(model);     }     [httppost]     public actionresult welcome(welcomevm model)      {        return view(model);      }     public object final { get; set; }  }  } 

index.cshtml

@{ viewbag.title = "welcome"; }  <br /> @html.label("name") <br /> @using (html.beginform("gender", "home", formmethod.post)) { @html.textbox("name"); <input id="btnsubmit" name="btnsubmit" placeholder="test" type="submit" value="submit" /> } 

gender.cs

using system.collections.generic; using system.web.mvc; public class welcomevm { public string name { set; get; } public string gender { set; get; } public ienumerable<selectlistitem> genders { set; get; } } 

gender.cshtml

@model welcomevm @using (html.beginform("welcome", "home", formmethod.post)) { <p>hello @model.name gender</p> @html.dropdownlistfor(m => m.gender, model.genders) @html.hiddenfor(s => s.name) <input type="submit" /> } 

welcome.cshtml

@{ viewbag.title = "welcome"; }  @model welcomevm <p>hello @model.name @model.gender</p> 

you not need session or viewbag pass data around. can use view model have.

so in index view,

@html.label("name")   @using (html.beginform("gender", "home")) {   @html.textbox("name");   <input id="btnsubmit" name="btnsubmit" type="submit"    value="submit" /> } 

and in gender action method use same view model parameter type. when form posted, default model binder map posted form values ot object of welcomevm class.

[httppost] public actionresult gender(welcomevm model) {    model.genders = new list<selectlistitem>    {          new selectlistitem { value="male", text="male"},          new selectlistitem { value="female", text="female"}    };    return view(model); } 

and in gender.cshtml view again typed same view model.

@model welcomevm @using (html.beginform("welcome", "home", formmethod.post)) {   <p>hello @model.name gender</p>   @html.dropdownlistfor(m => m.gender, model.genders)   @html.hiddenfor(s=>s.name)   <input type="submit" /> } 

and in welcome action

[httppost] public actionresult welcome(welcomevm model) {   return view(model); } 

and in welcome.cshtml view,which again typed view model,

@model welcomevm <p>hello @searchstring @model.gender</p>
