[Solved] After row Edit: Checkmark does not show correct value

[Frank Michael]

I have this grid:

c.Bound(r => r.Urgent).ReadOnly(false)
                .ClientTemplate("<input type='checkbox' disabled='disabled' name='Urgent' <#= Urgent? checked='checked' : '' #> />");
            c.Bound(r => r.Important).ReadOnly(false)
                .ClientTemplate("<input type='checkbox' disabled='disabled' name='Important' <#= Important? checked='checked' : '' #> />");

It is client bound.
I also have

 c.Command(s =>
            {
                s.Select();
                s.Edit();
                s.Delete();
            })

When I edit the row, the values are updated, but if the grid turns to display only mode again, then the new checked values are not displayed.
I have checked in the debugger, if the value is set and if it is correctly retrieved from the database.

        public ActionResult AjaxGridUpdate(string id)
        {
            var trans = new PlatformTransaction();
            var bon = new BusinessObjectNode<Workitem>(trans);

            bon.Retrieve(id);

            var workitem = bon.Entity(id);

            workitem.Title = Request.Form["Title"];
            workitem.RemainingDays = double.Parse(Request.Form["RemainingDays"]);
            workitem.RemainingHours = double.Parse(Request.Form["RemainingHours"]);
            workitem.Status = Request.Form["Status"];
            workitem.Urgent = bool.Parse(Request.Form["Urgent"]);
            workitem.Important = bool.Parse(Request.Form["Important"]);

            //if (TryUpdateModel<Workitem>(workitem, new string[] { "Title" }))
            //{
                workitem.ChangedAt = DateTime.UtcNow;
                workitem.ChangedBy = System.Web.HttpContext.Current.User.Identity.Name;

                bon.Update(workitem);

                trans.Save();
            //}

            var fatherId = workitem.SuperWorkitem;

            var vd = SelectGridModel(fatherId);

            return View(new GridModel(vd.gridRows));
        }

So yes, the value is set and it is correctly retrieved from the db. It is there in vd before I return it.
So it is a display problem

I just checked in the JSON return.
There strangely the value "Urgent" is not set. So in vd it is set, in the JSON reply not.

?!?!

Hold on - no. It is a save problem.
I believe the reason is, that I have save options that save only the non-null attributes. That's because the row of a table does not contain all attributes of the model object. I think I have to read the object completely before I update it. Or is there a possibility to read all attributes from the grid, even if they are not displayed?

[Frank Michael]

I solved it myself.
