In this article I will explain with an example, how to implement
Bootstrap 5
DatePicker in ASP.Net Core.
Controller
The Controller consists of following Action methods.
Action method for handling GET operation
Inside this Action method, simply the View is returned.
Action method for handling POST operation
This Action method gets called when the Button is clicked.
Inside this Action Method, the value of the selected Date is fetched and set into a
ViewBag object.
Finally, the View is returned.
public class HomeController : Controller
{
public IActionResult Index()
{
return View();
}
[HttpPost]
public IActionResult Index(string selectedDate)
{
DateTime dt = Convert.ToDateTime(selectedDate);
ViewBag.Message = "Selected Date: " + dt.ToShortDateString();
return View();
}
}
View
Inside the View, first the ASP.Net TagHelpers is inherited.
The View consists of an HTML Form which has been created using the ASP.Net TagHelpers with the following attributes.
asp-action – Name of the Action. In this case the name is Index.
asp-controller – Name of the Controller. In this case the name is Home.
method – It specifies the Form Method i.e. GET or POST. In this case it will be set to POST.
Inside the Form, there is a TextBox and a Submit Button.
Bootstrap 5 DatePicker Plugin implementation
Inside the View, the following CSS file is inherited.
1. bootstrap.min.css
2. bootstrap-datepicker.min.css
And then, the following JS script files are inherited.
1. jquery.min.js
2. bootstrap.bundle.min.js
3. bootstrap-datepicker.min.js
Inside the
jQuery document ready event handler, the TextBox has been applied with
Bootstrap 5
DatePicker plugin.
The
Bootstrap 5
DatePicker plugin has been assigned with the following properties:
changeMonth – Allows to change Month.
changeYear – Allows to change Year.
format – To set the selected Date in dd/MM/yyyy date format in TextBox.
Submitting the Form
When the Date is selected and the
Submit button is clicked, the Form is submitted and the
ViewBag object is checked for NULL and if it is not NULL then, the value of the
ViewBag object is displayed using
JavaScript Alert Message Box.
