Rendering DateTime to dd/mm/yyyy format in DataTable

Question

I'm trying to figure out how to render a DateTime value to short string or in the format of dd/mm/yyyy. I tried DateCreated.Value.ToShortDateString() and DateCreated.ToShortDateString(), but it doesn't seemed defined for a DataTable

My current output looks like 2017-04-23T17:39:20.687

How can I render it like dd/mm/yyyy in a DataTable?

@model IEnumerable<TestApp.Models.Announcement>
@{
    ViewBag.Title = "Announcement List";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>AnnouncementList</h2>

@Html.ActionLink("New Announcement", "New", "Annoucement", null, new {@class = "btn btn-primary"})


<table id="announcement" class="table table-bordered table-hover">
    <thead>
        <tr>
            <th>Title</th>
            <th>Description</th>
            <th>Date Created</th>
            <th>Delete</th>
        </tr>
    </thead>
    <tbody></tbody>

                        });
                });
        });
    </script>

and I put this

 public string FormattedDate => DateCreated.ToShortDateString();


 public DateTime DateCreated { get; set; }

in model

You could format the date in the client-side code that renders the DataTable — Maria Ines Parnisari

I think you´re mixing technologies here!

Either, provide a formatted string-representation in your Model like (C# 6 Syntax):

public string FormattedDate => DateCreated.ToShortDateString()

and pull this property in JavaScript via:

columns: [
                {
                    data: "dateCreated",
                    render: function(data, type, announcement) {
                        return announcement.FormattedDate;
                    }
                },

or, as Maria suggested, format the date directly on the client-side using techniques like explained here or with help of e.g.: moment.js

(Tha Client-Side JavaScript does not know anything about "ToShortDateString"-Method on a date...)

For this I'm getting the error: DataTables warning: table id=announcement - Requested unknown parameter 'dateCreated' for row 0, column 2. For more information about this error, please see datatables.net/tn/4 See code above for reference.

earloc Over a year ago

As both answers Are kind of correct, i would appreciate an upvote 😀.

Add this property to your model:

public string DateCreatedFormatted { get { return this.DateCreated.ToString("dd/MM/yyyy"); } }

Then bind to this property in your JavaScript code.

It should be "dd/MM/yyyy". Lowercase mm means minutes, not months.

Andy Over a year ago

I tried this and put it in to the table, but got the following error. See added code above for reference DataTables warning: table id=announcement - Requested unknown parameter 'dateCreatedFormatted' for row 0, column 2. For more information about this error, please see datatables.net/tn/4

@andy javascript is case sensitive so you must use DateCreatedFormatted

Andy Over a year ago

I wrote it in camel case because I added code that formats everything in camelcase and thought that's how I would need to add it in webapiconfig.cs var settings = config.Formatters.JsonFormatter.SerializerSettings; settings.ContractResolver = new CamelCasePropertyNamesContractResolver(); settings.Formatting = Formatting.Indented;

I figured out the issue. I was using Dto model and didn't put the formatted public string line in there so it didn't see it. Thanks for the help

I know that this post it is a old. I am show my solution working on asp.net Core 3.1 environment. My objective was to display a datetime value obtained from a database column with a datetime2(2) datatype, in a more clear format like dd-mm-yy HH:mm.

Required scripts:

 <script src="~/js/datagrid/datatables/datatables.bundle.js"></script>
 <script src="~/js/dependency/moment/moment.js"></script>

Solution shortcut:

   columns: [
            { title: "Username", data: "username" },
            {
                title: "Registration Date",
                data: "enrollmentTimeStamp",
                render: function (data, type, full, meta) {
                    return moment(data).format('DD-MM-YYYY HH:mm');
                }
            },
        ],

Good luck!
