Annoying MVC discovery of the day

When you try to retrieve the value of a checkbox on a form using
Request.Form.Get(keyname), the resulting value is "false" if the checkbox isn't checked, but if the checkbox IS checked, the returned value is "true,false". WTF?!!!! I mean seriously - WHAT THE F*CK?!!!!!!".45 ACP - because shooting twice is just silly" - JSOP, 2010

Wouldn't that be "true,false?"? That's equally absurd so, why the f*ck not, right?

It's almost as if the federal government had a hand in the implementation... It's no wonder the ObamaCare web site is so f*cked up.

Jack of all trades, master of none, though often times better than master of one.

The only two return values I've seen in MVC are "false", and "true,false". How other bastardized Microsoft frameworks handle it are not applicable.

WPF checkboxes have an
IsCheckedproperty that can be eitherfalse,true, ornull. When you want to check if the checkbox is really checked, you have to:if (checkbox.IsChecked == true)
{
...
}Butt-fugly.

delete this;Not to get too much into a programming discussion, this is the lounge, but you can also write it this way
if (checkbox?.IsChecked : false)
{
//...
}This way, if it IsChecked is null, it's still false. Leave it to Microsoft to create a system where nothing is something and you still can't divide by zero. :wtf:
if (Object.DividedByZero == true) { Universe.Implode(); }

This is the data send by the form on the HTML page. If instead of accessing raw values, you would let MVC load the values in a model, then the framework would handle that kind of stuff automatically. If you want to work at low level, then you have to understand the subtilities...

It'd be the same if you used Ruby or JavaScript. If you use MVC's built-in model binding, they abstract this away from the coder, if not, if you really want to access it via the Form object - a recommended approach is to use GetValues(name)[0].

I *am* using the helpers, and this has NOTHING to do with whether I'm using them or not. I'm using the standard method for retrieving the checked status from within a view. REGARDLESS of all of that, "true,false" as a return value is severely f*cked up.

Does it LOOK like I don't understand the "subtleties"? Returning "true,false" to indicate that a checkedbox is checked isn't a subtlety, it's f*cked up, or if you're too sensitive to call it what it really is (or you're just playing around, and not working on a real project), it's quirky.
