MVC Client side validation? - asp.net-mvc

Question

I have 3 textboxes ...one for day, second for month and third for year. I want to use mvc validation to check if one of this field is empty and then show *. Is it possible on button submit display just one error message if one of those fields are empty?
<div class="form-group">
<label for="dateofbirth" class="control-label col-lg-5">
#Html.Label(#BetXOnline.TranslationProvider.Instance.GetTranslationMessage("BIRTHDATE")):
#Html.ValidationMessage("*")
</label>
<div class="col-lg-2">
#Html.TextBoxFor(m => m.Register.Day, new { id = "day_birthdate", #class = "form-control" })
</div>
<div class="col-lg-2">
#Html.TextBoxFor(m => m.Register.Month, new { id = "month_birthdate", #class = "form-control" })
</div>
<div class="col-lg-3">
#Html.TextBoxFor(m => m.Register.Year, new { id = "year_birthdate", #class = "form-control" })
</div>

Answer 1

You can add the #ValidationMessageFor for all fields under same label.
<label for="dateofbirth" class="control-label col-lg-5">
#Html.Label(#BetXOnline.TranslationProvider.Instance.GetTranslationMessage("BIRTHDATE"))
:
#Html.ValidationMessageFor(m => m.Register.Day,"", new { #class = "text-danger" })
#Html.ValidationMessageFor(m => m.Register.Month,"", new { #class = "text-danger" })
#Html.ValidationMessageFor(m => m.Register.Year,"", new { #class = "text-danger" })
</label>

Answer 2

In your module class on the property attached with textbox provide attribute [Required].
than you can use of ValidationSummary which is already available in Asp.net MVC.
if you want to display message just beside file than do use ValidationMessageFor
Check : ASP.NET MVC Client Side Validation
class property definition for this
[Required(ErrorMessage = "*")]
public string Name { get; set; }
Example
<div class="editor-field">
#Html.EditorFor(model => model.Email)
#Html.ValidationMessageFor(model => model.Email)
</div>
