hi i use @Html.ValidationMessage("username") to check duplicate username .
and it is working. but when i have serverside validation error & clientside validation error together , it just shows clientside error .

@Html.ValidationMessage("username") alone works , but when i have forexample email required error too , @Html.ValidationMessage("username") doesn't show and just email error is shows.

i wanna when i click submit button , both error can to appear. these are not related to each other . server and client are diffrent .

C#

    //Client
@Html.TextBoxFor(m => m.email, new { @class = "group", @placeholder = "*  enter email" })
 @Html.ValidationMessageFor(model => model.email)


   //Server
  @Html.ValidationMessage("username")
  @Html.TextBoxFor(m => m.username, new {@id="group" , @class = "input-block-level", @placeholder = "* enter username" })

Hello,

you can do one thing, please see below explained example...

@Html.TextBoxFor(m => m.username, new {@id="group" , @class = "input-block-level",
@placeholder = "* enter username" })

@Html.ValidationMessageFor(m => m.username)

This will also work when you add Required attribute .

And

Also work for server side validation just you have to add this :-

when you excute your logic to check duplicate user, and if it finds duplicate user then set

ModeState.AddModelError("username",errorMessage)

errorMessage should be whatever you want to set.. (e.g "duplicate user found")

if it is useful then please vote for this answer.

Thanks
