htmlhelper checkbox checkboxfor ASP.NET MVC
In ASP.NET MVC, there are two HTML helpers that can be used to create a checkbox input element in a view: CheckBox
and CheckBoxFor
.
CheckBox
HTML helper:
TheCheckBox
HTML helper is a general-purpose helper method that creates a checkbox input element in the view. Here is an example usage ofCheckBox
:
@Html.CheckBox("IsAdmin")
This will generate an HTML input element with the name "IsAdmin" and a value of "true" when checked and "false" when unchecked. If you want to set the initial value of the checkbox, you can pass a second parameter to the helper method like this:
@Html.CheckBox("IsAdmin", Model.IsAdmin)
CheckBoxFor
HTML helper:
TheCheckBoxFor
HTML helper is a strongly-typed helper method that creates a checkbox input element for a property of the model that is passed to the view. Here is an example usage ofCheckBoxFor
:
@Html.CheckBoxFor(model => model.IsAdmin)
This will generate an HTML input element with the name "IsAdmin" and a value of "true" when checked and "false" when unchecked. The CheckBoxFor
helper method uses lambda expressions to generate the name and initial value of the input element based on the model property that is passed to it.
Using CheckBoxFor
is generally considered to be better practice than using CheckBox
because it provides stronger type checking and reduces the likelihood of runtime errors. Additionally, it helps to prevent against cross-site scripting (XSS) attacks by automatically encoding the input.
