What would I give to asp-for property of a label tag helper in order to display items from a collection. The code below generates a compilation error.
@foreach (var item in Model)
{
<label asp-for="item.BookingCode"></label>
}
What is Tag Helper? Tag Helper is a new feature in ASP.NET MVC 6 that enables the server-side code to create and render HTML elements, in MVC Razor View files. These are the objects which can be bound to the Models and based on these properties, HTML elements can be dynamically rendered.
Unlike HtmlHelpers, a tag helper is a class that attaches itself to an HTML-compliant element in a View or Razor Page. The tag helper can, through its properties, add additional attributes to the element that a developer can use to customize the tag's behavior.
The opt-out character (“!”) is used to disable the Tag Helper at the element level. With the opt-out character, the HTML will not be generated for the label tag in the above case. We can use this opt-out character if we want to conditionally control rendering of the HTML elements.
A Tag Helper Component is a Tag Helper that allows you to conditionally modify or add HTML elements from server-side code. This feature is available in ASP.NET Core 2.0 or later. ASP.NET Core includes two built-in Tag Helper Components: head and body . They're located in the Microsoft. AspNetCore.
The @
character escapes the default model lambda code. Therefore you can type:
@foreach (var item in Model)
{
<label asp-for="@item.BookingCode"></label>
}
