Grid with update but no create

[Rick]

Hi,

I have a requirement for a grid that allows a user to update a record but they cannot create new ones.  If my grid defines only the read and update action, when I save a record I get a 400 error returned but the save does go through.  The 400 error is returned before the save action has completed.  I have narrowed the issue down to the fact that I did not have a create action defined.

Why does a create action need to be defined even when there is no toolbar that allows them to add new records?

Simplified version of my grid definition:

    @(Html.Kendo().Grid<TimeStudy.NetCore.Web.Models.TSCodeAssociationModel>()
            .Name("gridTSCodeAssociation")
            .HtmlAttributes(new { sender = "gridTSCodeAssociation", title = "TS Code Associaton" })
            .Columns(c =>
            {
                c.Command(commands =>
                {
                    commands.Edit().Text(" ").CancelText("Close").UpdateText("Save").HtmlAttributes(new { title = "Edit Association" }).IconClass("fas fa-pencil-alt fa-xs iconColor k-sm").UpdateIconClass("rcit-k-remove-icon-span").CancelIconClass("rcit-k-remove-icon-span");
                }).ClientHeaderTemplate(TimeStudy.NetCore.Web.Common.ViewConstants.KENDO_REMOVE_FILTER_BTN).Width(55).Visible(@isEditor);
                c.Bound(f => f.TSCodeAssociationId).Hidden();
                c.Bound(f => f.Code).Width(50);
            })
            .Pageable()
            .Editable(ed => ed.Mode(GridEditMode.PopUp).TemplateName("EditTSCodeAssociation").Window(w => w.Title("Edit TS Code Association")))
            .DataSource(dataSource =>
            dataSource
            .Ajax()
            .Events(ex => ex.Error("function(e){gridWithSearchButton_onDataError(e, '#gridTSCodeAssociation')}"))
            .Model(model =>
            {
                model.Id(f => f.TSCodeAssociationId);
            })
            .Read(read => read.Action("GridTSCodeAssociationAction", "TSCodeAssociation", new { method = "read" }).Data("kendoPageSearchParametersAntiForgery"))
            .Update(read => read.Action("GridTSCodeAssociationAction", "TSCodeAssociation", new { method = "update" }).Data("kendoPageSearchParametersAntiForgery"))
            //.Create(create => create.Action("GridTSCodeAssociationAction", "TSCodeAssociation", new { method = "create" }).Data("kendoSendAntiForgery"))
            .PageSize(50)
            )
            .Events(e => e.DataBound("kendoGridLoadButtonReset_databound"))
            .Filterable(filterable => filterable
            .Extra(false)
            .Operators(operators => operators
            .ForString(str => str.Clear()
            .StartsWith("Starts with")
            .IsEqualTo("Is equal to")
            .IsNotEqualTo("Is not equal to")
            .Contains("Contains")
            ))
            )
            .Scrollable(s => s.Height(600))
            .Sortable()
            .AutoBind(true)
        .Deferred()
        )

 

If I leave the create action commented out I get the 400 error message and I can see the network call shown in the attached image right before the grid update call.

Hi Richard,

Based on the provided information, I suspect that the call is performed outside of the grid. This is because I could not see any endpoints that are called timestudy. I suspect that there might be an event handler or any generic JS logic that might be triggering the call. 

Is it possible for you to isolate the problem in a sample and send it back to me so that I can investigate it? I would recommend that you perform a global search for the timestudy keyword and see all the places that is used. After that track what invokes this function.
