Here's my model's property:
[Required(ErrorMessage = "Debe escribir su fecha de nacimiento")]
[Display(Name = "Fecha de Nacimiento")]
[DataType(DataType.Date)]
public DateTime DateOfBirth { get; set; }
In my AccountController, I create a new object of this model and pass it to the View:
<div class="editor-label">
#Html.LabelFor(model => model.DateOfBirth)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.DateOfBirth)
#Html.ValidationMessageFor(model => model.DateOfBirth)
</div>
Remember, at this point this is a Create form. The model's properties have no values.
However, this is rendered in my HTML.
Is there some way to tell the view engine to not render anything in this field?
If you change your definition to a Nullable, then it'll start off as null and no value will be displayed if one isn't set (which by default it isn't).
public DateTime? DateOfBirth { get; set; }

I have created the register page on mvc3 razor. I want to put the validation on user notification field. Below is my code.
[Required]
[Display(Name = "Student Notification ?")]
[Range(typeof(bool), "true", "true", ErrorMessage = "You gotta tick the box!")]
public Boolean UserNotification { get; set; }
Below is my register page view
<div class="editor-label">
#Html.LabelFor(model => model.UserNotification)
</div>
<div class="editor-label">
#Html.CheckBoxFor(model =>model.UserNotification)
#Html.ValidationMessageFor(model => model.UserNotification)
</div>
<p>
<input type="submit" value="Register" />
</p>
So when i will click the button, there should be validation message there ..
You need to change your datatype of the property UserNotification. Change:
public Boolean UserNotification { get; set; }
To:
public bool UserNotification { get; set; }
There is a lot difference between Boolean and bool.
I am building an ASP.Net MVC 3 Web application using Entity Framework 4.1. To perform validation within one of my Views which accepts a ViewModel. I am using Data Annotations which I have placed on the properties I wish to validate.
ViewModel
public class ViewModelShiftDate
{
public int shiftDateID { get; set; }
public int shiftID { get; set; }
[DisplayName("Start Date")]
[Required(ErrorMessage = "Please select a Shift Start Date/ Time")]
public DateTime? shiftStartDate { get; set; }
[DisplayName("Assigned Locum")]
public int assignedLocumID { get; set; }
public SelectList AssignedLocum { get; set; }
}
View
#using (Html.BeginForm())
{
#Html.ValidationSummary(true)
<br />
<div class="editor-label">
#Html.LabelFor(model => model.shiftStartDate)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.shiftStartDate, new { #readonly = "readonly" })
#Html.ValidationMessageFor(model => model.shiftStartDate)
</div>
<br />
<div class="editor-label">
#Html.LabelFor(model => model.assignedLocumID)
</div>
<div class="editor-field">
#Html.DropDownListFor(model => model.assignedLocumID, Model.AssignedLocum)
#Html.ValidationMessageFor(model => model.assignedLocumID)
</div>
<br />
<p>
<input type="submit" value="Save" />
</p>
<br />
}
The SelectList 'AssignedLocum' is passed into my View for a DropDownList, and the item selected is assigned to the property 'assignedLocumID'.
As you can see from my ViewModel, the only required field is 'shiftStartDate', however, when I hit the Submit button in my View, the drop down list 'AssignedLocum' also acts a required field and will not allow the user to submit until a value is selected.
Does anyone know why this property is acting as a required field even though I have not tagged it to be so?
Thanks.
Try to use default value for dropdown (for example "Please select")
#Html.DropDownListFor(model => model.assignedLocumID, Model.AssignedLocum, "Please select")
I thought I have asked this before, but I am not finding it. I am making partial view for a form so I can use it in multiple places. Here is one short snippet:
#model Permits.Domain.Entities.PermitRequest
#using (Html.BeginForm())
{
#Html.ValidationSummary(true)
<div class="editor-label">
#Html.LabelFor(model => model.JobAddress)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.JobAddress)
#Html.ValidationMessageFor(model => model.JobAddress)
</div>
<p>
<input type="submit" value="Submit request" />
</p>
</fieldset>
}
My model looks like:
public class PermitRequest
{
[Description("Job address")]
public string JobAddress { get; set; }
}
Why would my label still be "JobAddress" instead of "Job Address" (with the space)? I feel like I am missing something obvious.
[DisplayName("Job address")]
public string JobAddress { get; set; }
or if you prefer:
[Display(Name = "Job address")]
public string JobAddress { get; set; }
Both set the DisplayName property of the ModelMetadata which is used by the LabelFor helper.
I'm trying to get my viewmodel set up for a form that will collect information about people joining a team. The form must contain some leadup information, then a list of 5 "Team Members" (each containing a name, email, and phone), the first two of which will be required. For my validation I would like it to be on the individual fields, like this:
Person 1:
Name: (validation messaage)
Email: (validation message)
Phone: (validation message)
Person 2:
Name: (validation messaage)
Email: (validation message)
Phone: (validation message)
Person 3:
Name:
Email:
Phone:
Person 4:
Name:
Email:
Phone:
Person 5:
Name:
Email:
Phone:
The relevant portion of my viewmodel is currently:
[Required]
public TeamMember TeamMember1 { get; set; }
[Required]
public TeamMember TeamMember2 { get; set; }
public TeamMember TeamMember3 { get; set; }
public TeamMember TeamMember4 { get; set; }
public TeamMember TeamMember5 { get; set; }
so in my view, I just write:
#Html.EditorFor(model=>model.TeamMember1)
#Html.EditorFor(model=>model.TeamMember2)
#Html.EditorFor(model=>model.TeamMember3)
#Html.EditorFor(model=>model.TeamMember4)
#Html.EditorFor(model=>model.TeamMember5)
the editor template looks like this:
#model MyProject.Models.TeamMember
<div class="editor-label">
#Html.LabelFor(model => model.Name)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Name)
#Html.ValidationMessageFor(model => model.Name)
</div>
<div class="editor-label">
#Html.LabelFor(model => model.Email)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Email)
#Html.ValidationMessageFor(model => model.Email)
</div>
<div class="editor-label">
#Html.LabelFor(model => model.Phone)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Phone)
#Html.ValidationMessageFor(model => model.Phone)
</div>
Sorry for throwing so much into one thread, but does anyone have a suggestion as to how best to set this up? I've thought about inheriting from RequiredAttribute and replacing [Required] on the TeamMember properties, but I'm not sure how to set the validation messages on the child fields. Right now, even if it's empty it passes the required check, I'm assuming because the objects are bound (and so not null) even though all of the properties are blank.
Any feedback is appreciated.
You can write a custom validator. Below is an example of how you can access the values of other properties. You can then either decorate TeamMember or the property with this custom
validation attribute depending on the validation logic. I would recommend it at the class level
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
//Retreive value of Name property
var nameProperty = validationContext.ObjectType.GetProperty("Name");
var namePropertyValue = (string)nameProperty.GetValue(validationContext.ObjectInstance, null);
var propertyBeingValidatedValue = (string)value;
//Validation logic
if ((!string.IsNullOrEmpty(propertyBeingValidatedValue)) && (!string.IsNullOrEmpty(namePropertyValue)))
{
//returning null means everything is good.
return null;
}
//return a message in any other case.
return new ValidationResult("Validation Message");
}
I have this model:
public class ExchangeRate
{
[Key]
public int ExchangeRateID { get; set; }
[Required]
[Display(Name = "Currency:")]
public string Currency { get; set; }
[Required]
public decimal Rate { get; set; }
}
The "Create" view is working fine, but when I am in the edit view, I only want the Currency property to be displayed, and not editable. How should I do this? If I create another "view-only" model for this class, then I would omit the "Currency" property and would not be able to display it.
#using (Html.BeginForm()) {
#Html.ValidationSummary(true)
<fieldset>
<legend>ExchangeRate</legend>
#Html.HiddenFor(model => model.ExchangeRateID)
<div class="editor-label">
#Html.LabelFor(model => model.Currency)
</div>
<div class="editor-field">
#Html.DisplayFor(model => model.Currency)
</div>
<div class="editor-label">
#Html.LabelFor(model => model.Rate)
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Rate)
#Html.ValidationMessageFor(model => model.Rate)
</div>
<p>
<input type="submit" value="Save" />
</p>
</fieldset>
}
Changing #Html.EditorFor(model => model.Currency) to #Html.DisplayFor(model => model.Currency) doesn't work because the model state becomes invalid when it posts back to the controller.
You could add
#Html.HiddenFor(model => model.Currency)
in your form and then use
#Html.DisplayFor(model=> model.Currency)
to display the readonly value of the currency property. That way when you post the value will be sent along in the posted model.
You're looking for:
[HiddenInput(DisplayValue=true)]
Then show the editor, not the display (use EditorFor).
This displays the value read-only, but adds a hidden input so that the posted state is valid.
To display the currency but not edit it try
#Html.Label("Currency", Model.Currency)
if you also need to post the currency value back to the controller try
#Html.HiddenFor(m => m.Currency)
I hope this helps.
