TextBoxFor Helper in MVC3 Razor
- Html.TextBoxFor is the helper which renders a TextBox.
- Helpers are not controls by itself, they simply generate html markup.
- Html.TextBoxFor binds the control to the model.
- It accepts linq expression which helps in model binding.
It has following overloads :
Overload 1 :
This overload accepts a linq expression, which binds the property to the model.
Syntax :
<p>
@Html.TextBoxFor(c => c.Password)
</p>
UI :
Rendered HTML :
<p>
<input id="Password" name="Password" type="text" value="" />
</p>
Overload 2 :
This overload accepts two parameters, linq expressiona and htmlAttributes object.
Syntax :
<p>
@Html.TextBoxFor(c => c.Password, new { maxlength = "10"})
</p>
UI :
Rendered HTML :
<p>
<input id="Password" maxlength="10" name="Password" type="text" value="" />
</p>
The maxlength attribute is set to 10 as passed by htmlAttributes object.
Overload 3 :
This overload is similar to previous one, just that it accepts IDictionary object of htmlAttributes.
Syntax :
<p>
@Html.TextBoxFor(c => c.Password,textBox)
</p>
We have created a Dictionary of attributes and passed as parameter.
UI :
Rendered HTML :
<p>
<input id="Password" maxlength="10" name="Password" style="color:Red" type="text" value="" />
</p>
