it causes problems at the two Using data-* and I can not pardon to enter it.

 @Html.TextBox("txtFornavn", null, new
 {
  @class = "form-control input-lg",
  placeholder = "Fornavn",
  data-val="true",
  data-val-required="Date is required",
  type = "date"
 })

Normally, my html part like this.

<input type="date" class="form-control input-lg" data-val="true" data-val-required="Date is required">

 @Html.TextBox("txtFornavn", null, new
  {
   @class = "form-control input-lg",
   placeholder = "Fornavn",
   type = "date"

the link posted gave you your answer. You have to use underscore _ if you want to use dashes in an attribute name

 @Html.TextBox("txtFornavn", null, new
 {
  @class = "form-control input-lg",
  placeholder = "Fornavn",
  data_val="true",
  data_val_required="Date is required",
  type = "date"
 })

did you try that?

Also have a look at the following wordpress article: Using HTML 5 data- It contains jQuery code to test whether the properties are being set. It may be beneficial to you.
