asp.net mvc - MVC ModelState.Clear isn't updating ModelState -

in mvc program, once user has submitted edit form, values object saved in model server-side, previous values show in view.

i know has mvc's validation process, first checks modelstate before server side values. solution i've read across forums clear modelstate. problem is, modelstate.clear isn't working me.

help please.

model

public class     {         [hiddeninput(displayvalue=true)]         public int helpid { get; set; }          [required(errormessage = "please enter proper url")]         public string url { get; set; }          [required(errormessage = "please enter content description:")]         [datatype(datatype.multilinetext)]         public string helpcontent { get; set; }          /*? 2 properites nullable*/         public datetime? createdatetime { get; set; }         public datetime? modifieddatetime { get; set; }             } 

controller

partial view (gets loaded div) `

@using (html.beginform(null, null, formmethod.post, new { id = "editx" })) {     @html.validationsummary(true)     <fieldset>         <legend>edit entry</legend>         @html.hiddenfor(model => model.helpid)         <div class="editor-label">             @html.labelfor(model => model.url)         </div>         <div class="editor-field">            @html.editorfor(model => model.url)            @html.validationmessagefor(model => model.url)         </div>         <div class="editor-label">             @html.labelfor(model => model.helpcontent, "help content")                     </div>          <div class="editor-field">        @{     html.telerik().editorfor(content => content.helpcontent)       .name("helpcontent")         .filebrowser(settings => settings           .browse("browse", "imagebrowser")           .thumbnail("thumbnail", "imagebrowser")           .upload("upload", "imagebrowser")           .deletefile("deletefile", "imagebrowser")           .deletedirectory("deletedirectory", "imagebrowser")           .createdirectory("createdirectory", "imagebrowser")       )       .render();         }         @html.validationmessagefor(model => model.helpcontent)         </div>          <div class="editor-label">             @html.labelfor(model => model.createdatetime, "create date")         </div>         <div class="editor-field">             @html.editorfor(model => model.createdatetime)             @html.validationmessagefor(model => model.createdatetime)         </div>          <div class="editor-label">             @html.labelfor(model => model.modifieddatetime, "modified date")         </div>         <div class="editor-field">             @html.editorfor(model => model.modifieddatetime)             @html.validationmessagefor(model => model.modifieddatetime)         </div>         <p>             <input id="btnedit" type="submit" value="save" />             <button id="btncancel">cancel</button>         </p>     </fieldset>     } 

after trolling through hundred links, found solution problem. modelstate.clear clears objects values in controller, whatever reason still displaying old values in view. maybe because load/unload edit form div tag? don't ask. don't know. solution works me this:

$.ajax({  url: "somecontroller/someaction, cache: false, // key make sure jquery not cache request success: function( data ) { alert( data ); } });  

i had set "cache" setting "false".

thanks @minus4 solution, bruh.
