here code have far:

@html.labelfor(model => model.consumergenderid)                         @(html.kendo().dropdownlist()                                 .name("gender")                                 .htmlattributes(new { @style = "align:center; font-size:12px; width:208px; length:35px" })                                 .optionlabel("please select")                                 .value("-1")                                 .datatextfield("optionname")                                 .datavaluefield("optionid")                                 .datasource(source =>                                 {                                     source.read(read =>                                     {                                         read.action("getgenderstatus", "consumerdetails");                                     });                                 })                          )                         @html.validationmessagefor(model => model.givenname1, " ")                   </div> 

model

required(errormessage = "please select gender")]         [uihint("gridforeignkey")]         [displayname("gender")]         public int consumergenderid { get; set; }         public string consumergendername { get; set;  

}

try matching names of 2 fields. eg "gender" , givenname1 not equivalent right there enough keep validation firing if weren't kendo dropdown.

perhaps try use dropdownfor it's little easier keep track of.

@html.kendo().dropdownlistfor(m=>m.givenname1) @html.validationmessagefor(m=>m.givenname1)
