The error message is on the span class="display-mode".

How do I find out what these invalid arguments are?

 grid.Column("BillMonthly",
                            style: "col2",
                            format: @<text>
                                <span class="display-mode">@Html.CheckBox("billmonthly-display", item.BillMonthly, new { disabled = "disabled" })</span>
                                @Html.CheckBox("BillMonthly", item.BillMonthly, new { @class = "edit-mode" })
                            </text>)

var billmonthly = tr.find('#BillMonthly').attr('checked') ? true : false;

'/Methods/ChangeBarn',
                    { OwnerId: ownerid, ProviderId: providerid, StateId: stateid, Zip: zip, Location: location, Address: address, City: city, LName: lname, FName: fname, Email: email, Mobile: mobile, BillMonthly: billmonthly},
                    function (barn) {
                        tr.find('#providerid').text(barn.ProviderId);
                        tr.find('#location').text(barn.Location);
                        tr.find('#address').text(barn.Address);
                        tr.find('#city').text(barn.City);
                        tr.find('#state').text(barn.State);
                        tr.find('#zip').text(barn.Zip);
                        tr.find('#lname').text(barn.LName);
                        tr.find('#fname').text(barn.FName);

                    }, "json");

That says that at least one of the parameters you are passing in doesn’t fit the required data type. It’s looking for a string, a bool and an object. The string and object look fine to me, so that leaves the bool. What data type is BillMonthly in the database?

The datatype is bit., however some of the records are NULL.

This is the reason!

Now I get a checkbox when Edit is selected.  What happens after that is a whole new thread.

P.S. you tutorial code now has a checkbox , which is very helpful, however there is no mention of it on your site.

So it’s actually a nullable bool. You need to test to see if it has  value:

item.BillMonthly.HasValue ? item.BillMonthly.Value : false
