I have an MVC3 application with a model that contains a DeployedDate property of the type DateTime?. In my view I want to only show the date in the text box but not the time.
<%: Html.EditorFor(model => model.DeployedDate) %>
<%: Html.ValidationMessageFor(model => model.DeployedDate) %>
If you are open to modify Model, You can use DisplayFormatAttribute. You can specify ApplyFormatInEditMode
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
public DateTime? DeployedDate{ get; set; }

I want to show placeholder value in text box if Model Cost value is '0', but it's showing default '0'. What is incorrect in the following code?
<div class="leftflotdiv">
#if (Model.SkillSets[j].Cost > 0)
{
#Html.TextBoxFor(x => x.SkillSets[j].Cost, new { #class = "input_newmainbg", placeholder = "Cost per hour", Value = Model.SkillSets[j].Cost })
}
else
{
#Model.SkillSets[j].Cost
#Html.TextBoxFor(x => x.SkillSets[j].Cost, new { #class = "input_newmainbg", placeholder = "Cost per hour" })
}
</div>
Try this. Make the name of the field according to your model field to bind the input field to the model property.
<input type="text" name='SkillSets[#j].Cost' placeholder="Cost per hour" class = "input_newmainbg" />
I am trying the following RegEx to validate the decimal value like
[RegularExpression("^(?:\\d{1,100000000}(?:\\.\\d{0,6})?)?$")]
[Range(double.MinValue,double.MaxValue)]
public decimal Amount { get; set; }
rendering in the view like
<div class="editor-field">
<%:Html.TextBoxFor(x=>x.Amount)%>
<%:Html.ValidationMessageFor(x=>x.Amount) %>
</div>
the problem is it puts a 0 in the textbox by default, please guide me find out the problem, also if there is a better way to validate the decimal field please do mention...
Try settings the type of your Amount property to nullable:
public decimal? Amount { get; set; }
i'm trying to put DropDownList validation to work.
in model:
[Required(ErrorMessage = "this field is required")]
public int ObjectTypeID { get; set; }
in view:
<div class="editor-field">
#Html.DropDownList("ObjectTypeID", string.Empty)
#Html.ValidationMessageFor(model => model.ObjectTypeID)
</div>
if the user leaves the selection empty i expect client side validation to alarm. but this does not happen.
what can be done?
The behavior of system types is that they must have a value when initalized. An integer has a value of "0". Change your model to accept a nullable int:
public int? ObjectTypeID { get; set; }
Just wondering, but why not use DropDownListFor?
For client side validation to work I think you need to turn on ClientValidationEnabled & UnobtrusiveJavaScriptEnabled in the web.config for your project, I believe you also need to reference the jquery.validate.unobtrusive.min.js script on your page?
1) You are not loading your dropdownlist
2) Use DropDownListFor in order to match validation with ddl
i just wanted to know how to enable client side validations for dropdowns in asp.net mvc 2.
The scenario would be that the dropdown will contain a "Select" item and the list of other items..,The user should select other items... the validation should fire when the user does not select the other items
public class FacilityBulletinModel
{
[DisplayName("Select a Facility")]
public List<SelectListItem> ListFacility { get; set; }
[DisplayName("Facility Bulletin")]
[Required(ErrorMessage = "Please create a Bulletin")]
public string FacilityBulletin { get; set; }
[DisplayName("Active")]
public bool Active { get; set; }
[HiddenInput(DisplayValue = false)]
public int SiteId { get;set;}
}
in my view
Select Facility <span class="err">*</span><br />
<%=Html.DropDownListFor(model => model.ListFacility, null, new {onChange="updateSiteId()" })%>
<span class="err"> <%= Html.ValidationMessageFor(model => model.ListFacility) %></span>
First, if a dropdown is required, add the [Required] attribute to your model property.
Then, enable client side validation somewhere at the top of your view:
<% Html.EnableClientValidation() %>
Then just add a validation message:
<div class="inputField">
<%= Html.LabelFor(model => model.property)%>
<%= Html.DropDownListFor(model => model.property, (SelectList)ViewData["myselelectlist"])%>
<%= Html.ValidationMessageFor(model => model.property)%>
</div>
(this requries MicrosoftMvcValidation.js to be loaded)
today I got confused when doing a couple of <%=Html.LabelFor(m=>m.MyProperty)%> in ASP.NET MVC 2 and using the [DisplayName("Show this instead of MyProperty")] attribute from System.ComponentModel.
As it turned out, when I put the attribute on an overridden property, LabelFor didn't seem to notice it.
However, the [Required] attribute works fine on the overridden property, and the generated errormessage actually uses the DisplayNameAttribute.
This is some trivial examplecode, the more realistic scenario is that I have a databasemodel separate from the viewmodel, but for convenience, I'd like to inherit from the databasemodel, add View-only properties and decorating the viewmodel with the attributes for the UI.
public class POCOWithoutDataAnnotations
{
public virtual string PleaseOverrideMe { get; set; }
}
public class EditModel : POCOWithoutDataAnnotations
{
[Required]
[DisplayName("This should be as label for please override me!")]
public override string PleaseOverrideMe
{
get { return base.PleaseOverrideMe; }
set { base.PleaseOverrideMe = value; }
}
[Required]
[DisplayName("This property exists only in EditModel")]
public string NonOverriddenProp { get; set; }
}
The strongly typed ViewPage<EditModel> contains:
<div class="editor-label">
<%= Html.LabelFor(model => model.PleaseOverrideMe) %>
</div>
<div class="editor-field">
<%= Html.TextBoxFor(model => model.PleaseOverrideMe) %>
<%= Html.ValidationMessageFor(model => model.PleaseOverrideMe) %>
</div>
<div class="editor-label">
<%= Html.LabelFor(model => model.NonOverriddenProp) %>
</div>
<div class="editor-field">
<%= Html.TextBoxFor(model => model.NonOverriddenProp) %>
<%= Html.ValidationMessageFor(model => model.NonOverriddenProp) %>
</div>
The labels are then displayed as "PleaseOverrideMe" (not using the DisplayNameAttribute) and "This property exists only in EditModel" (using the DisplayNameAttribute) when viewing the page.
If I post with empty values, triggering the validation with this ActionMethod:
[HttpPost]
public ActionResult Edit(EditModel model)
{
if (!ModelState.IsValid)
return View(model);
return View("Thanks");
}
the <%= Html.ValidationMessageFor(model => model.PleaseOverrideMe) %> actually uses [DisplayName("This should be as label for please override me!")] attribute, and produces the default errortext "The This should be as label for please override me! field is required."
Would some friendly soul shed some light on this?
Model binding and metadata using the strongly-typed helpers looks at the declared, rather than the runtime, type of the model. I consider this a bug, but apparently the MVC team disagrees with me, as my Connect issue on this was closed as "By Design."
I ran into this problem using [DisplayName("Profile Name")] and instead used [Display(Name = "Profile Name")] which fixed the problem in my case. I'm not sure if this would be useful.
The former is from System.ComponentModel whilst the latter is from System.ComponentModel.DataAnnotations.
I had the same issue when I had a partial view strongly-typed to an interface. The interface defined a DisplayName and the class that implemented the interface tried to override it. The only way I found to get it to respect the override was to type to the implementing class. I had to either change the view's model type or cast. Unfortunately, that completely negates the benefits of using the interface as the model type. I am guessing that I will end up with some level of duplicated view markup for each implementing class while not casting within the strongly-typed "helpers".
In the remote chance that this type of workaround is even remotely helpful (not getting my hopes up), here is an example. There are certainly ways of working handling into this for all possible implementing classes that try to override a name, but it is definitely more hassle than it should be.
public interface IAddressModel {
...
[DisplayName("Province")]
public string Province { get; set; }
...
}
public class UsAddressModel : IAddressModel {
...
[DisplayName("State")]
public string Province { get; set; }
...
}
<%= Html.LabelFor(m => m.State) %> <!--"Province"-->
<%= Html.LabelFor(m => (m as UsAddressModel).State) %> <!--"State"-->
Ok, I seem to have found a workaround if you don't use the Required tag with it! just use a regular expression or length attribute to determine if there is a valid entry. Hope this helps, though it's a little late.
[RegularExpression(#"^[1-9][0-9][0-9]$")] //validates that there is at least 1 in the quantity and no more than 999
[DisplayName("Quantity:")]
public string quantity { get; set; }
Still works.
In my case I was forgotten to make it a property by using getters and setters.
Instead of
public string CompanyName;
I should have used
public string CompanyName {get;set;}
