I have these questions
How do I remove time from datetime (01/01/2017 instead of 01/01/2017 00:00:00)
How do I display on year (2017 instead of 01/01/2017 00:00:00)
See the view below
<td>
#Html.DisplayFor(modelItem => item.PAYMENT_YEAR)
</td>
PAYMENT_YEAR is DateTime in the database. I want to do it from view
You can call the ToShortDateString() method on the DateTime object. This will give you the short date string representation from that DateTime value.
<td>item.PAYMENT_YEAR.ToShortDateString()</td>
If you want just the year, you may access the Year property.
<td>item.PAYMENT_YEAR.Year</td>
You can use the Year property with the Html.DisplayFor helper method
<p>#Html.DisplayFor(modelItem=>item.PAYMENT_YEAR.Year)</p>
But you cannot make a method call inside DisplayFor. So you may just go with
<td>item.PAYMENT_YEAR.ToShortDateString()</td>
If the type of PAYMENT_YEAR property nullable DateTime (DateTime), you need to do a null check before calling the helper method
if (item.PAYMENT_YEAR.HasValue)
{
<span>#Html.DisplayFor(modelItem => item.PAYMENT_YEAR.Value.Year)</span>
}
Or you can simply print the value without using the helper method along with null conditional operator
<td>item.PAYMENT_YEAR?.Year</td>

Can I configure the HTML Helper to display String.Empty if my date is MinValue?
${Html.TextBoxFor(v=>v.Date)}
How can I do this?
Why don't you do it in your View?
Caution: Razor syntax
#if(v.Date != DateTime.MinValue)
{
Html.TextBoxFor(v => v.Date);
}
else {
//show whatever
}
There are a few similar questions like
Html.TextboxFor default value for Integer/Decimal to be Empty instead of 0
Display empty textbox using Html.TextBoxFor on a not-null property in an EF entity
If you have full control over the viewmodel, one option would be to make the date field nullable and have the accessor return null if the date is equal to DateTime.MinValue.
If you don't want to change your viewmodel, you can write your own html helper and put the logic to create an empty textbox there. That allows you to keep logic out of your view, where it's difficult to test.
Make your property nullable and it won't default to the min date. If that's a database field and you can't do that then you should create a ViewModel property that is and have it compare against the min value and return null in the get{}
In my Model I have the following :
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:H:mm}")]
public DateTime _time { get; set; }
In my Edit View in the Textbox the value that is set is the full Date and time and when ever i try manually to edit the value through the browser the jQuery Validations Yields an error that the date format is not correct
while I'm adding ApplyFormatInEditMode=true why in the textbox I'm getting the Full Date the the formated one (only time) and why the jQuery validator throw error when the format is time only without date and how can I by pass it?
You should use Html.EditorFor and not Html.TextBoxFor if you want the custom format to be applied:
#Html.EditorFor(x => x._time)
Also by naming a property _time you are violating at least 2 C# naming conventions (property names start with an uppercase letter and not with an underscore).
I have a model with a DateTime property that in one place is placed in a hidden input field.
#Html.HiddenFor(m => m.StartDate)
Which generates the following HTML:
<input id="StartDate" name="StartDate" type="hidden" value="1/1/2011 12:00:00 AM" >
The problem is that the time is included in the value and my custom date validation expects a date in the format of ##/##/#### thus causing validation to fail. I can easily alter my custom date validation to make this situation work but I would rather make it so that the hidden field puts the value in the correct format.
I have tried using the DisplayFormat attribute on the model property but that doesn't seem to change the format of the hidden input.
I do realize that I could just create the hidden input manually and call StartDate.ToString("MM/dd/yyyy") for the value but I am also using this model in a dynamically generated list of items so the inputs are indexed and have ids like Collection[Some-Guid].StartDate which would make it a bit more difficult to figure out the id and name of the input.
Is there anyway to make the 'value' value come out in a specific format when rendering the field on the page as a hidden input?
You could use a custom editor template:
public class MyViewModel
{
[UIHint("MyHiddenDate")]
public DateTime Date { get; set; }
}
and then define ~/Views/Shared/EditorTemplates/MyHiddenDate.cshtml:
#model DateTime
#Html.Hidden("", Model.ToString("dd/MM/yyyy"))
and finally in your view use the EditorFor helper:
#model MyViewModel
#Html.EditorFor(x => x.Date)
This will render the custom editor template for the Date property of the view model and consequently render the hidden field with a value using the desired format.
I have variables like:
DateTime crd = a.CreationDate; (shown as a variable in C# but available in razor views)
I want to show these as a date using the format: 11/06/2011 02:11
Ideally I would like to have some kind of HTML helper for this. Anyone out there already have something that might meet my needs?
You could create a Display Template or Editor Template like in this answer, but the format would apply to all DateTime variables in the given scope (maybe good or bad).
Using the DisplayFormat attribute works well to define formats for individual fields.
Remember to use #Html.DisplayFor(model=>model.crd) and/or #Html.EditorFor(model=>model.crd) syntax for either of the above.
You can always use the DateTime.ToString() method in your views as well for more ad hoc formatting.
#crd.ToString("MM/dd/yyyy HH:mm") // time using a 24-hour clock
in your model you can set [DisplayFormat] attribute with formatting as you wish
[DisplayFormat(DataFormatString = "{0:dd MMM yyyy}")]
pubilc DateTime CreationDate{ get; set }
Use this code to format your date:
#string.Format("{0:ddd}",Convert.ToDateTime(Html.DisplayFor(model => model.Booking.BookingFromDate).ToString()))
If your date field with required attribute then you don't want to validate null value.
Other wise you can use ternary operator
How about
#crd.ToShortDateString()
Try Razor View
#Html.Raw(item.Today_Date.Date.ToString("dd.MM.yyyy"))
In the interest of completeness, you could also use string interpolation. I don't think this was an available feature when this question was asked.
#($"{crd:dd/mm/yyyy HH:mm}")
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/tokens/interpolated
If you have a list of dates and want to grab the first:
Begin Date: #string.Format("{0:MM/dd/yyyy}", Convert.ToDateTime(Model.aList.Where(z => z.Counter == 1).Select(z => z.Begin_date).First()))
I have a date time picker combination in a edit template that can be used like Html.EditorFor(x => x.ETA) but now I want to use the same template somewhere where I don't have a model that contains a DateTime property. So I tried Html.Editor("DateWithTime", "Arrival") which uses the correct template, but doesn't assign a value to ViewData.ModelMetadata.PropertyName which is something that my template relies on. It sets the id of the textbox which is obviously important.
Is there a way to render the template and assign a id value to the ViewData.ModelMetadata.PropertyName so I can re-use the logic in the template instead of having to copy it?
Maybe use ViewData.TemplateInfo.HtmlFieldPrefix instead of ViewData.ModelMetadata.PropertyName.
I am not sure but I thought that HtmlFieldPrefix an PropertyName have the same value as long as you do not iterate a collection.
You can modify the HtmlFieldPrefix property with the htmlFieldName parameter from Html.Editor.
You can use the UIHint in your model. give it the name of the template you want to use
[UIHint("DateWithTime")]
You still use EditorFor with this.
