Html.Raw blazor - Html

Blazor is an exciting new framework for building web applications using C#. One of the features of Blazor that developers find useful is Html.Raw in blazor. It is a method that allows access to raw HTML code inside a component.

With Html.Raw, you can insert unencoded HTML content directly into your Blazor component. This is useful when you need to display formatted content like tables, lists, or other HTML elements.

Syntax

The syntax for using Html.Raw in Blazor is simple. First, you need to import the Microsoft.AspNetCore.Components namespace in your component file as shown below.

@using Microsoft.AspNetCore.Components

Then, you can use the Html.Raw method to display HTML content as shown below.

<div>@Html.Raw("<strong>Hello, World!</strong>")</div>

Note that you should always escape any user-generated content that you want to display using Html.Raw. This is because unescaped HTML can lead to security vulnerabilities like cross-site scripting (XSS) attacks.

Example

Here's an example of using Html.Raw in Blazor to display a table of data.

<table>
    <thead>
        <tr>
            <th>Name</th>
            <<th>Age</th>
        </tr>
    </thead>
    <tbody>
        @foreach (var person in People)
        {
            <tr>
                <td>@person.Name</td>
                <td>@person.Age</td>
            </tr>
        }
    </tbody>
</table>

@code {
    private List<Person> People { get; set; }

    protected override void OnInitialized()
    {
        People = new List<Person>
        {
            new Person { Name = "John", Age = 30 },
            new Person { Name = "Jane", Age = 25 },
            new Person { Name = "Tom", Age = 40 }
        };
    }

    private class Person
    {
        public string Name { get; set; }
        public int Age { get; set; }
    }
}

In the above example, we display a list of people in a table. The Html.Raw method is used to display the table headers and rows in their raw HTML form.

Conclusion

Html.Raw in Blazor is a powerful feature that allows you to insert raw HTML content directly into your components. However, you should always escape any user-generated content to avoid security vulnerabilities.
