NullReferenceException when using latest version (2024.1.130) of kendo.custom.min.js

From https://www.telerik.com/download/custom-download# I tried to download the latest version 2024.1.130 kendo.custom.min.js file in order to upgrade the kendo plugin  from Kendo UI 2022.1.412 version to the latest. 
I use Asp.Net MVC and I have a custom bundler where I reference all the js files like this

 bundles.Add(new ScriptBundle("~/bundle/kendo").Include( "~/Scripts/kendo/kendo.custom.min.js"));

Then in Razor Layout page I register bundles like this

@Scripts.Render("~/bundle/kendo")

but whenever I run the application I always get a NullReferenceException at the line that registers the bundle with the message "No object reference is set to an object instance."

Whenever I downgrade the kendo version or return to the previous one the application runs properly.

Any ideas why is this happening? Would you please help me solve this issue? 

Thanx in Advance.

Is it possible to change the calendar week start day of the week?

Can we change the starting day of the week from Sunday to Monday? i.e. MO, TU, WE, TH, FR, SA, SU

Or Sunday to Saturday? i.e. SA, SU, MO, TU, WE, TH, FR

Instead of the current: SU, MO, TU, WE, TH, FR, SA

Can we force user to only be able to select whole weeks?
Is it possible to make it so if a user clicks a day it selects the whole week, like clicking the week number does? Then is it also possible to capture multiple selected weeks (not necessarily concurrent weeks or in the same month), even if all the dates in those selected weeks are the output that would be fine

How do you emulate a user typing input into a combo box?

My page has a combo box. As the user selects an ID from the dropdown list, the page populates with information corresponding to the entry. It is an AJAX bound combo box. I am trying to make the combo box get auto populated with an ID from my query string on initialization. 

I've tried setting the .Value field of the combo box. This works to automatically select the correct ID and populate the rest of the page, but only when the ID exists in the data source. My AJAX call returns data based on the partial/full ID passed in, and a list of a few most recent ID's if no input ID is specified. 

I believe this will work if the ID exists in the data source prior to setting the value field of the combo box. But for that to happen, the combo box must use the ID from the url to fetch the data source, similar to what happens when a user manually types that ID into the combo box. However, I am struggling to figure out how to pass in a specific ID when the combo box is responsible for making the AJAX call. 

I would appreciate any advice or other suggestions to getting the intended behavior.

Validate Date for Kendo Filter Field

I am using a Kendo.Filter object like the following to filter results in a Kendo Grid:

@(Html.Kendo().Filter<CustomPersonClass>()
     .Name("personFilter")
     .DataSource("peopleDS")
     .ApplyButton(false)
     .Fields(f =>
     {
         f.Add(p => p.LastName).Label("Last Name");
         f.Add(p => p.FirstName).Label("First Name");
         f.Add(p => p.MiddleName).Label("Middle Name");
         f.Add(p => p.StartDate).Label("Start Date").Operators(o => o.Date(d => d.Eq("Is equal to").Gte("Greater than equal").Lte("Less than equal")));
     })
)

 I have helper code to handle the toolbar in my Kendo Grid like the following, :

@helper ToolbarTemplate()
{
    <button class="k-button k-button-solid k-button-solid-base" id="applyFilter"><span class="k-icon k-i-filter"></span>Apply Filter</button>
    <button class="k-button k-button-solid k-button-solid-base" id="clearFilter">Reset</button>
    <button class="k-button k-grid-excel k-button-solid k-button-solid-base"><span class="k-icon k-i-excel"></span>Export to Excel</button>
}

I also have some JavaScript in a function to apply the filter when the Apply Filter button is clicked, as seen here:

$("#applyFilter").click(function (e) {
    //e.preventDefault();
    var myFilter = $("#personFilter").getKendoFilter();
    localStorage["kendo-person-filter-options"] = kendo.stringify(myFilter.getOptions().expression);
    myFilter.applyFilter();
});

 

The problem I am having is if I enter an invalid Leap Year date (e.g. 2/29/2003, since 2023 didn't have a February 29th), I get no data back; however, if I enter a valid Leap Year (e.g. 2/29/2004), my Kendo Grid will show data.  Is there a way to validate the date that is being entered manually into a DatePicker field used for filtering?  That is, if I use the DatePicker, it will not show me 2/29/2003 as an option, but if I type in 2/29/2003 and click Apply Filter, it doesn't throw any kind of error about 2/29/2003 being invalid.

Input controls growing and shrinking when loading data

Controls loading icon stretching fields

As you can see fields grow and shrink due the the loading icon right of the dynamic controls being larger than the control I believe

Is this a bug or something I can do to resolve

Calendar month view is not showing data when current month is not selected.

I use the following code to show the calendar:

<div class="section">
    <script id="event-template" type="text/x-kendo-template">
        <div class="item-template" title="#: title #">
            <div class="title">#: title #</div>
        </div>
    </script>
    <div class="daily-container">
        @(Html.Kendo().Scheduler<WaterFlowReadingModel>()
    .Name("Daily")
	.Events(e =>
	{
		e.Navigate("scheduler_navigate");
		e.DataBound("scheduler_databound");

	})
    .Date((DateTime)ViewBag.Month)
    .StartTime((DateTime)ViewBag.Month)
	.EventTemplateId("event-template")
    .Views(v =>
    {
        v.MonthView();
    })
	.DataSource(d =>
		d.Model(m =>
		{
            m.Id(f => f.Id);
            m.RecurrenceId(f => f.RecurrenceRule);
			m.Field(f => f.Title).DefaultValue("No title");
		}).ServerOperation(true)
		.Read(read => read.Action("GetMetricDaily", "Metric",
			new { type = 1, start = ViewBag.Month.AddMonths(-1), end = ViewBag.Month.AddMonths(1) }))
    ))
    </div>
</div>

Javascript:

    function scheduler_navigate(e) {
        var start = kendo.format('{0:d}', this.view().startDate());
        var end = kendo.format('{0:d}', this.view().endDate());

        $.ajax({
            url: "@(Url.Action("GetMetricDaily", "Metric"))",
            data: {
                start: start,
                end: end,
            }, success: function () {

                var scheduler = $("#Daily").data("kendoScheduler");

                scheduler.refresh();
            }
        });
    }

    function scheduler_databound(e) {
        var today = e.date;
        var scheduler = $("#Daily").data("kendoScheduler");
        var newDate = scheduler.date();
        console.log(newDate, today);
		$.ajax({
			url: "@(Url.Action("GetStatistics", "Metric"))",
			dataType: "json",
			data: {
				month: kendo.format('{0:d}', newDate),
            }, success: function (data) {
				//console.log(data);
				date = new Date(data.ReportingPeriod.match(/\d+/)[0] * 1);
                $("#TotalMonthlyDischargeVolume").val(data.TotalMonthlyDischargeVolume);
                $("#NumberOfDaysOfDischargeToSewer").val(data.NumberOfDaysOfDischargeToSewer);
				$("#MaximumDailyFlow").val(data.MaximumDailyFlow);
                $("#ReportingPeriod").val(kendo.toString(date, "Y"));
            }
        });
    };

The problem is that when I select a different month, no data at all is shown unless I select the current month again, which then shows current data.

Controller code:


        public ActionResult GetMetricDaily([DataSourceRequest] DataSourceRequest request, DateTime start, DateTime end)
        {
            using (var db = new DatabaseContext())
            {
                // Water flows
                var lastMonth = db.WaterFlows
                    .Where(w => w.TimeStamp > start && w.TimeStamp < end && w.TotalizerReading >= 1)
                    .Select(x => new WaterFlowReadingModel()
                    {
                        Title = x.TotalizerReading.ToString(),
                        Start = x.TimeStamp,
                        End = x.TimeStamp,
                        Id = x.Id,
                    }).ToList();
                
                // pH Readings
                var result = db.pHReadings.Where(w => w.TimeStamp > start && w.TimeStamp < end)
                    .GroupBy(o => EntityFunctions.TruncateTime(o.TimeStamp))
                    .Select(g => new
                    {
                        Date = g.Key,
                        Min = g.Min(o => o.pHValue),
                        Max = g.Max(o => o.pHValue),
                        Avg = g.Average(o => o.pHValue)
                    })
                    .ToList();
                
                var output = new List<WaterFlowReadingModel>();
                foreach (var item in result)
                {
                    var title = $"PH - Min: {item.Min:F} / Max: {item.Max:F} / Avg: {item.Avg:F}";
                    output.Add( new WaterFlowReadingModel()
                    {
                        Title = title,
                        Start = item.Date ?? DateTime.Today,
                        End = item.Date ?? DateTime.Today,
                        Id = 0
                    });
                }

                lastMonth.AddRange(output);
                return Json(lastMonth.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);
            }
        }

Kendo MVC UI File Manager Templates

Any sample templates available for Kendo MVC UI File Manager that replicate Windows file explorer including appropriate icons for folders and files?

I  can see how to create and reference the templates, but could use the time savings if someone has already done this. 

The only sample in the demos is for the preview panel. How about the tree view, list view and grid view within the file manager?

ASP.NET MVC Wizard AJAX Partial Views and how to save the model.

After a long day, I finally got all the validation working as I intend it.  The question I now have is how do I pass the model back and forth between each step?   My basic setup is I have Business.cshtml that has my Wizard on it.  For each step of the wizard I then  retrieve the correct PartialView and render to the step.  What I am unsure of how to do is how do you pass the model back and forth.  I made the assumption using '@Url.Action("_BusinessFinancial", "Onboard",Model)' in the javascript would work but I am just not 100% how to save the model between each step and reuse it.

 

Here is my Business.cshtml

 


@using Kendo.Mvc.UI
@model Reverberate.BLL.Model.Form.Application.BusinessOnboarding.BusinessOnboardingModel

@{
    ViewBag.Title = "Business Onboarding";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<style>
    .wide {
        width: 95%;
    }

    .field-validation-error {
        color: red;
    }
</style>


<!-- Wizard -->
@(Html.Kendo().Wizard()
        .Name("wizard")
        .Events(ev => ev.Select("onSelect"))
        .Events(ev => ev.Done("onDone"))
        .LoadOnDemand(true)
        .HtmlAttributes(new { @novalidate = "" })
        .ReloadOnSelect(false)
        .Steps(s =>
        {
            s.Add<Reverberate.BLL.Model.Form.Application.BusinessOnboarding.BusinessOnboardingModel>()

            .ContentUrl(Url.Action("_BusinessProfile", "Onboard", Model))
            .Buttons(b =>
            {

As recommend in my other question here: I have created a sample project.   In this project there is an Index.cshtml which has my original structure.  With regards to the index.cshtml there are two things, one - I am not sure why validation doesn't occur on the original page load, I have to reload the page to force page validation and also on the done command there isn't any validation occuring.

 


I created ind.cshtml when I trying the recomemnded solution for the question here: https://www.telerik.com/forums/using-wizard---how-do-you-validate-a-form-when-step-includes-partial-view#5789804 and I am getting `

Using Wizard - how do you validate a form when step includes partial view.

I'm pretty much at the point I give up.  All I want to do is use the Wizard to load partial views for each step, and all I want to do is prevent the next step if the form can't be validated.  I've tried nearly everything for 3 days and I can't seem to find an answer.  I've tried jquery..validate and it just goes no where.

 

I just have a real simple setup, Business.cshtml which contains the wizard


@using Kendo.Mvc.UI
@model Reverberate.BLL.Model.Form.Application.BusinessOnboardingModel

@{
    ViewBag.Title = "Business Onboarding";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<style>
    .wide {
        width: 95%;
    }

    .field-validation-error {
        color: red;
    }
</style>



    <!-- Wizard -->
    @(Html.Kendo().Wizard()
        .Name("wizard")
        .Events(ev => ev.Select("onSelect"))
        .Events(ev => ev.Done("onDone"))
        .LoadOnDemand(true)
        .ReloadOnSelect(false)
        .Steps(s =>
        {
            s.Add<Reverberate.BLL.Model.Form.Application.BusinessOnboardingModel>()
            .Title("Business Profile")
            .ContentUrl(Url.Action("_BusinessProfile", "Onboard"))
            .Buttons(b =>
            {
                b.Next().Text("Next");
            });

            s.Add<Reverberate.BLL.Model.Form.Application.BusinessOnboardingModel>()
