Make radio buttons "checkable": HTML -

-

How do I work radio buttons like a check box? I need a radio button function, but it should be able to choose.

Usually this is done by adding another option, users will not expect "none" Clicking on a selected radio button will unselect it because it is not a normal behavior.

Another option, which is no longer used, is a "clean" button I do not like this option.

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends.
