Question

I have some html checkboxes on a page and I need to verify that they have been check in the postback event for the page.

The data for these checkboxes is not stored in a database, they just have to be checked before the use can go to the next page.

How do i verify that they are checked? I don’t see them in the Request.Form.AllKeys collection

<input id='terms_eligibility' type='checkbox'   />
<input id='terms_accurate' type='checkbox' />
<input id='terms_score_release' type='checkbox' />

---

EDIT
Here’s what I ended up doing

View

 @Html.CheckBox("terms_eligibility")

Controller

string eligibility = Request.Form.GetValues("terms_eligibility")[0];

Answer 1

When a HTML checkbox is not checked then its value is not sent back to the webserver.

MVC solves this problem by adding an <input type="hidden" /> for each checkbox which ensures that a value is always sent, so it can detect if a checkbox was checked or not.

To use these hidden inputs you must use the Html.CheckBox or Html.CheckBoxFor helper methods.

Anyway, the HTML you posted doesn’t have any name="" attributes. HTML inputs must have a name attribute. They don’t use the id attribute for form field keys.
