Check Box Utilities in ASP.NET

By xrmlabs webmaster on 4/24/2013

By this article I want to just describe the utility of check box and compare to the radio buttons . In the radio button list user is restricted to select at least one selection user can not escape the choice but in the check box list user is not restricted to select a choice even he can go for no choice also .

(1)If you want  to restrict the user to check only one check and he can not go for no choice
(2) If you want  to restrict the user to check on more than one check box(desirable number)  from the check box list  or he can go for no choice .

Here are two  java script functions by these function you can achieve the above tasks .

In the first function user is restricted to check only one check box and it  is compulsory.

In the second function user is restricted to check a particular number of check boxed in the example restriction for two check boxes user is also free to go for no choice also .

                var subs = $('#<% = CheckBoxSubjects.ClientID %> input:checkbox');
                for (i = 0; i < subs.length; i++) {
                    if (i == selectedIndex)
                        subs[i].checked = true;
                    else
                        subs[i].checked = false;
                }
            });
        });

            var chkchoice = document.getElementById("<%=CheckBoxFoodchoice.ClientID%>");
            var checkbox = chkchoice.getElementsByTagName("input");
            var counter = 0;
