The HtmlHelper class includes two extension methods TextBox() and TextBoxFor<TModel, TProperty>() that renders the HTML textbox control <input type="text"> in the razor view. It is recommended to use the generic TextBoxFor<TModel, TProperty>() method, which is less error prons and performs fast.
Data attributes will have a syntax like “data-*”. If you add the hyphen within the name of an attribute, Razor interprets this as a minus sign. To add a data attribute within an HTML helper, replace the hyphen with an underscore. Razor recognizes this and converts it to a hyphen.
Show activity on this post. TextBoxFor: It will render like text input html element corresponding to specified expression. In simple word it will always render like an input textbox irrespective datatype of the property which is getting bind with the control. EditorFor: This control is bit smart.
IMO the main difference is that Textbox is not strongly typed. TextboxFor take a lambda as a parameter that tell the helper the with element of the model to use in a typed view. You can do the same things with both, but you should use typed views and TextboxFor when possible.
You could use underscore (_) and the helper is intelligent enough to do the rest:
@Html.TextBoxFor(
model => model.Country.CountryName,
new { data_url = Url.Action("CountryContains", "Geo") }
)
And for those who want to achieve the same in pre ASP.NET MVC 3 versions they could:
<%= Html.TextBoxFor(
model => model.Country.CountryName,
new Dictionary<string, object> {
{ "data-url", Url.Action("CountryContains", "Geo") }
}
) %>
