c# - Validation not worked on kendoUI multiselect -

-

i creating form using mvc4. here used kendo multiselect , try validate through model annotation.

my code : 

@model webapp._2012.models.deviceinventory.devicetechnologymodel  <script src="~/scripts/jquery.validate.unobtrusive.min.js"></script>  @using (ajax.beginform("create", "device_technologyinventory", new ajaxoptions { httpmethod = "post", onsuccess = "onsuccessaddtechnology" })) { @html.validationsummary(true)  <table width="100%" cellspacing="0" cellpadding="0" border="0">   <tr>     <td>       <@html.labelfor(model=>model.name)</td>     <td class="editor-field" width="160px;">       @html.editorfor(model => model.name) @html.validationmessagefor(model => model.name)     </td>   </tr>    <tr>     <td>@html.labelfor(model => model.alias)</td>     <td class="editor-field">       @html.editorfor(model => model.alias) @html.validationmessagefor(model => model.alias)     </td>   </tr>    <tr>     <td>@html.labelfor(model => model.vendors)/td>       <td class="editor-field">         @(html.kendo().multiselectfor(model=>model.vendors) .name("vendors").placeholder("select") .bindto(new selectlist(viewbag.vendorlist, "value", "text")) ) @html.validationmessagefor(model => model.vendors)       </td>   </tr> </table>  <div class="createwrp">   <input type="submit" value="create " class="btn-success"/>   <input type="reset" value="reset " class="btn-primary" /> </div>

my model :

    public class devicetechnologymodel     {         public int id { get; set; }         [required(errormessage = "*")]         [display(name = "device technology")]         public string name { get; set; }         [required(errormessage = "*")]         [display(name = "alias")]         public string alias { get; set; }         [required(errormessage = "*")]         [display(name = "device vendors")]         public list<string> vendors { get; set; }     }

when clicked on submit button validation error message appear on both "name" , "alias" field not on field "vendors".

i not want use javascript validation.

you need validate value not list object.

you may need make below changes in model:

public class devicetechnologymodel {         public int id { get; set; }         [required(errormessage = "*")]         [display(name = "device technology")]         public string name { get; set; }         [required(errormessage = "*")]         [display(name = "alias")]         public string alias { get; set; }          [required]         [required(errormessage = "*")]         [display(name = "device vendors")]         public int vendorid { get; set; }          public list<string> vendors { get; set; } }

in view:

<tr>     <td>@html.labelfor(model => model.vendors)/td>       <td class="editor-field">         @(html.kendo().multiselectfor(model=> model.vendorid)                       .name("vendors").placeholder("select")                       .bindto(new selectlist(viewbag.vendorlist, "value", "text")))         @html.validationmessagefor(model => model.vendorid)       </td>   </tr>

make sure when submit form vendorid property holds value or not.

if has nothing validation should work.

hope helps.
