Views in ASP.NET
Learn about views in ASP.NET Core.
To present data stored in your database to the user in an elegant and user-friendly way, use views. Views in
The views generated map to your controller’s action methods. The Index()
method has a view called Index.cshtml
and Create()
method has a view called Create.cshtml
and so on.
Focus on those parts of views that allow you to take data from your models and display them to the user.
Importing model data into views
@model IEnumerable<<t>People.Models.User</t>>
declared at the start of a view allows you to read different model class properties. In this case, you can read User
classes’ properties and extract data accordingly.
Accessing model class properties
@Html.DisplayNameFor(model => model.Name)
allows you to access the model classes’s property name and represent it into your view. The advantage of using this syntax instead of hardcoding a string is because the model might have an property name but a different display name. For example, the property PhoneNumber
will be displayed as “Phone Number” because of Display
attribute.
Iterating through data
If you wish to utilize some sort of a loop in your views that iterates through an entire table, use @foreach
. The complete syntax will be: @foreach (var item in Model)
. Data per iteration is accessed from a variable called item
.
Accessing data in each iteration
Data can be extracted by using item.
which is followed by the property name. item.Name
will provide you with names stored in your database from the Users
table. The complete syntax for this functionality is: @Html.DisplayFor(modelItem => item.Name)
Calling action function
To call an action function of a controller, use asp-action
followed by the function name. For example, asp-action="Edit"
calls the Edit()
function from the controller.
Passing data to action function
If you call an action function and you also wish to pass ID
parameters, asp-route-id
can be used. For example asp-route-id="@item.ID"
will pass ID
associated with item
. Furthermore, item
will contain an instance of data from each iteration of @foreach
loop.
