The label tag helper generates appropriate for attribute values and content based on the PageModel property that is assigned to it. It has just one attribute:
| Attribute | Description |
|---|---|
for |
An expression to be evaluated against the current page model |
Notes
The label tag helper is intended to work alongside the Input tag helper. It takes a property of the PageModel as a parameter to the asp-for attribute and renders the name of the property as a value for the label's for attribute and as the content of the label tag. Assuming that the PageModel has a property named "Email:
<label asp-for="Email"></label>
This renders as
<label for="Email">Email</label>
Note that the closing tag is required. If you use a self-closing tag e.g. <label asp-for="Email" />, the content will not be rendered.
You can override the value that is rendered in the label in two ways. The first option is to provide an alternative value:
<label asp-for="Email">Email Address</label>
Alternatively, you can use the Data Annotations Display attribute to change the content that is rendered:
[Display(Name="Email Address")]
public string EmailAddress { get; set; }
Both of these approaches will render as
<label for="EmailAddress">Email Address</label>
