HiddenFor helper in MVC3 Razor
- Html.HiddenFor is the helper which renders a Hidden field.
- Helpers are not controls by itself, they simply generate html markup.
- Html.HiddenFor renders input type = "hidden".
- It binds the control to the model property. It created stongly binded view.
It has following overloads :
This overload accepts linq expression, which binds the control to the model property.
Syntax :
<p>
@Html.HiddenFor(c => c.Address)
</p>
Rendered HTML :
<p>
<input id="Address" name="Address" type="hidden" value="" />
</p>
Overload 2 :
This overload accepts two parameter, i.e. expression and htmlAttributes object.
Syntax :
<p>
@Html.HiddenFor(c => c.Address, new { isHidden = true })
</p>
Rendered HTML :
<p>
<input id="Address" isHidden="True" name="Address" type="hidden" value="" />
</p>
Overload 3 :
This overload is similar to the previous one, it accepts IDictionary object of htmlAttributes instead of htmlAttributes object.
Syntax :
<p>
@Html.HiddenFor(c => c.Address, hidden)
</p>
Rendered HTML :
<p>
<input id="Address" isHidden="True" name="Address" type="hidden" value="" />
</p>
We have created an IDictionary object of htmlAttributes and assigned a custom attribute named isHidden to it. We can see in Rendered HTML that the attribute is created and set with respective value we have passed.
Good. Thanks! (o)
