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>

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>

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>
