asp.net mvc: simulating autopostback for simple checkbox

Question

I have a simple checkbox, generated with:

<%= Html.CheckBox("myCB" )%>

How can I add an onChange handler to this that does a submit?

Answer 1

Add an onClick handler to the CheckBox that submits the form the CheckBox belongs to...quick, clickHandler codeless example:

<%= Html.CheckBox("myCB", 
    new { onClick = "$(this).parent('form:first').submit();" });

(example definitely not checked for accuracy)

Answer 2

If you have only one form, and are not using JQuery (you should be, by the way) try this:

<%= Html.CheckBox("myCB", 
new { onClick = "document.form.submit();" });
