Question

I have an HTML helper textBox like this:

@Html.TextBox("txt1") <br />

Now I want to fire a javascript onchange event on this textbox. Is it possible to do so or should I use an HTML input type instead.

Answer 1

You can specify html attributes using the htmlAttributes parameter of the TextBox Html helper method like so:

@Html.TextBox("txt1", null, new { onchange="..." })

See: InputExtensions.TextBox Method

From the above link:

The htmlAttributes parameter consists of an object that contains
name/value pairs. The attributes that are specified in the name/value
pairs depend on the HTML element that is being rendered.
