Reference a control's ID created with TextBoxFor()

I am loving ASP.NET MVC, keeping up with the releases/docs can sometimes be tricky, so maybe I'm just not getting something... I want to use a TextBoxFor(), and working with LabelFor() etc. is fine, all the magic happens for me.

But if I create...

 <%=Html.TextBoxFor(x => x.LastName) %>开发者_如何转开发;

And wanted to do something nice with jQuery, how would I get the ID of the control that was created? I could add a CSS class and use that to attach my jQuery, but for something I am doing I would like the ID... so I could do something like:

 $('#LastName').(...)

I know I could work it out in this case, and hack it in manually, but is there a neater way?

I think you can do something like:

<%=Html.TextBoxFor(x => x.LastName, new { id = "LastName" })%>

Overloads of TextBoxFor

Since MVC4 there is a built-in way to do it - @Html.IdFor().

Here is a sample of using it:

@Html.IdFor(m => m.Filters.Occurred.From)

and the result is like

Filters_Occurred_From

As a point of interest it appears that the Html.Textbox() code will generate an id, duplicating the control name for anything that begins with a letter (a-z). If however your 'name' begins with a number it will simply not bother.

This is a fantastic 'feature' that has caused me grief for the past hour or so.

By default your control id is your model binding value, You can also Just use firebug. select the control and get by default control id.
