What's the difference between Html.Label, Html.LabelFor and Html.LabelForModel
What's the difference between @Html.Label()
, @Html.LabelFor()
and @Html.LabelForModel()
methods?
Html.Label
gives you a label for an input whose name matches the specified input text (more specifically, for the model property matching the string expression):
// Model
public string Test { get; set; }
// View
@Html.Label("Test")
// Output
<label for="Test">Test</label>
Html.LabelFor
gives you a label for the property represented by the provided expression (typically a model property):
// Model
public class MyModel
{
[DisplayName("A property")]
public string Test { get; set; }
}
// View
@model MyModel
@Html.LabelFor(m => m.Test)
// Output
<label for="Test">A property</label>
Html.LabelForModel
is a bit trickier. It returns a label whose for
value is that of the parameter represented by the model object. This is useful, in particular, for custom editor templates. For example:
// Model
public class MyModel
{
[DisplayName("A property")]
public string Test { get; set; }
}
// Main view
@Html.EditorFor(m => m.Test)
// Inside editor template
@Html.LabelForModel()
// Output
<label for="Test">A property</label>
Html.Label
- Just creates a label tag with whatever the string passed into the constructor is
Html.LabelFor
- Creates a label for that specific property. This is strongly typed. By default, this will just do the name of the property (in the below example, it'll output MyProperty if that Display attribute wasn't there). Another benefit of this is you can set the display property in your model and that's what will be put here:
public class MyModel
{
[Display(Name="My property title")
public class MyProperty{get;set;}
}
In your view:
Html.LabelFor(x => x.MyProperty) //Outputs My property title
In the above, LabelFor will display <label for="MyProperty">My property title</label>
. This works nicely so you can define in one place what the label for that property will be and have it show everywhere.
I think that the usage of @Html.LabelForModel()
should be explained in more detail.
The LabelForModel Method returns an HTML label element and the property name of the property that is represented by the model.
You could refer to the following code:
Code in model:
using System.ComponentModel;
[DisplayName("MyModel")]
public class MyModel
{
[DisplayName("A property")]
public string Test { get; set; }
}
Code in view:
@Html.LabelForModel()
<div class="form-group">
@Html.LabelFor(model => model.Test, new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Test)
@Html.ValidationMessageFor(model => model.Test)
</div>
</div>
