its not a good idea, to stop the user, if the user want enter more value then you have to change the code again, dont restrict the user

Would need to see your code but you could use a regular expression, String.split or a variation of substr and indexOf()

Hi Guys,

I have done code for that..this is the solution

C#

$('#txtAddTags').keyup(function () {
                //debugger;
                //alert('1')
                var TotalTags = $('#txtAddTags').val().split(',');
                if (TotalTags.length <= 20) {
                    for (var Index = 0; Index < TotalTags.length; Index++) {
                        if (TotalTags[Index].length <= 16) {
                        }
                        else {
                            alert('Max chars should be 16.');
                            TotalTags[Index] = TotalTags[Index].substr(0, TotalTags[Index].length - 1);
                            // TotalTags[Index] = TotalTags[Index].substr(16);
                            var TagValue = "";
                            for (var i = 0; i < TotalTags.length; i++) {
                                TagValue += TotalTags[i] + ","
                            }
                            TagValue = TagValue.substr(0, TagValue.length - 1);
                            $('#txtAddTags').val(TagValue);
                            //$('#txtAddTags').val($('#txtAddTags').val().substr(0, $('#txtAddTags').val().length - 1))
                            //$('#txtAddTags').val($('#txtAddTags').val().substr(0, $('#txtAddTags').val().length - 1))
                            return false;
                        }
                    }
                }
                else {
                    alert('Max tag should be 20.');
                    $('#txtAddTags').val($('#txtAddTags').val().substr(0, $('#txtAddTags').val().length - 1))
                    return false;
                }
            });
