Grid in Bootstrap 4 Modal can drag but cannot drop

HI

I have a grid with row reorder enabled in bootstrap 4 pop up modal.

I can drag the row but cannot drop the row to another position., It works outside of modal.

Can I know is there anything extra to set or need a hack to allow the dropping of row to reorder them?

My code below:

Note: Datasource is set on document ready script.

<div class="modal fade" id="ServiceDetailModal" role="dialog" aria-labelledby="ServiceDetailModalLabel" aria-hidden="true" data-backdrop="static" data-keyboard="false">
<div class="modal-dialog" role="dialog">

<form id="ServiceDetailModalForm" autocomplete="off" >

<div class="modal-content">

<div class="modal-header pb-0">
Services Detail
</div>
<div class="modal-body">

@(
Html.Kendo().Grid<DSPJobServiceItems>()
.Name("modalServiceDetail_ServiceFeeItem")
.Editable(editable => editable.Mode(GridEditMode.InCell))
.Navigatable(true)
.Reorderable(r => r.Rows(true))
.Events(e => e.Edit("ServiceFeeEdit").RowReorder("modalServiceDetail_ServiceFeeItemRowReorder"))
.Columns(columns =>
{
columns.Template("").Width(50).Draggable(true);
columns.Bound(p => p.GeneralServiceTitle).Title("Service Item");
})
)

</div>

<div class="modal-footer">
<button type="button" class="k-button btn-danger">Close</button>
</div>
</div>
</form>
</div>
</div>

Grid search doesn't work when operator explicitly specified

This is my grid:

@(Html.Kendo().Grid<Project>()
    .Name("ProjectsGrid")
    .Columns(columns =>
    {
        columns.Bound(p => p.ProjectName)
            .ClientTemplate("<a href=/Directory/project/${Id} target=_blank>${ProjectName}</a>")
            .Width(180);
        columns.Bound(p => p.ProjectManager).Width(230)
            .ClientTemplate("#=data.ProjectManager?.Name#")
            .EditorTemplateName("WorkingEmployee")
            .Sortable(s => s.Compare("(a, b) => compareManager(a, b)"));
        columns.Bound(p => p.IsActive)
            .Width(180)
            .ClientTemplate("#: IsActive ? 'Yes' : 'No' #");
    })
    .ToolBar(toolbar =>
    {
        toolbar.Save();
        toolbar.Search();
    })
    .Search(s =>
    {
        s.Field(e => e.IsActive);
        s.Field(e => e.ProjectName, "contains");
    })
    .Sortable()
    .Editable(GridEditMode.InCell)
    .DataSource(dataSource => dataSource
        .Ajax()
        .Batch(true)
        .ServerOperation(false)
        .Events(events => events.Error("error_handler"))
        .Model(model =>
        {
            model.Field(p => p.ProjectManager).DefaultValue(
                ViewData["defaultProjectManager"] as User);
            model.Field(p => p.ProjectName).Editable(false);
        })
        .Read("Projects_Read", "Directory")
        .Update("Projects_Update", "Directory")
    ))

With "s.Field(e => e.ProjectName, "contains");" it throws:

Uncaught TypeError: e.charAt is not a function kendo.all.js:2114

Without this, it runs correctly.

Additional question

Also, I would like to know how to search for value of bool variable. The variable is shown as yes, no words. When I search for no, it should show me records where value is false. How to implement this?

Issue with RadioGroupFor .ToClientTemplate (2023.2.718 buid)

I'm trying to add a RadioGroupFor control to a Toolbar control as a templated item but am getting a JS error related to the generated client template.

Here is the template definition:

<script id="ApproveOrDenyTemplate" type="text/x-kendo-template">
    @(Html.Kendo().RadioGroupFor(model => model.ApproveOrDeny)
        .Layout(RadioGroupLayout.Horizontal)
        .HtmlAttributes(new { style = "display: inline-flex; vertical-align: top;" })
        .LabelPosition(RadioGroupLabelPosition.After)
        .Items(i =>
        {
            i.Add().Label("Approve").Value("Approve");
            i.Add().Label("Deny").Value("Deny");
        })
        .Events(e => e.Change("changeApproveOrDeny"))
        .ToClientTemplate()
    )
</script>

Here is the Toolbar templated item entry:

items.Add()
    .TemplateId("ApproveOrDenyTemplate")
    .Hidden(!Model.ShowApprovalRadioGroup);

Here is the error being thrown and the generated client template javascript (the bold red code is what shows as offending text in console.log) - have I defined the template wrong or is the toolbar item entry wrong?

VM48:1 Uncaught SyntaxError: Unexpected token '<'
kendo.syncReady(function(){jQuery("\#ApproveOrDeny").kendoRadioGroup({"change":changeApproveOrDeny,"items":[{"label":"Approve","value":"Approve"},{"label":"Deny","value":"Deny"}],"value":"Approve","layout":"horizontal","labelPosition":"after"});});<\/script>

Disabling (making readonly) a whole bunch of datepickers on a form.

I've got a page which contains a dozen tabs, each of which has their own ViewComponent. Each ViewComponent has many datepicker controls.

I have a situation where I need to disable almost all of them, except on one tab, based on the user's role.

What are some ways to do this in one fell swoop, rather than setting .Enable(false) on each individual datepicker in markup?

Bonus: there are some regular old <input type="text">'s on these forms as well. Those are easy enough to disable with JQuery, but JQuery doesn't work on the datepickers, because while the text portion is read-only, the popup button displaying a calendar still works and can change the value of the text box.

Thanks so much for any ideas!

IHtmlHelper does not contain definition for Kendo .NET 7

I am using AspNet Core MVC 7

I am trying to create a custom HTML helper outside of a razor view. I am using the IHtmlHelper in this scenario and unfortunately outside of a razor view I cannot do something like this:

var uploader = _helper.Kendo().Upload()
                .Name("uploadFiles")
                .Multiple(true)
                .HtmlAttributes(new { style = "margin: 15px 0 5px 0;" });

Compilation error:

Error CS1061 'IHtmlHelper' does not contain a definition for'Kendo'

and no accessible extension method 'Kendo' accepting a first argument of

type'IHtmlHelper' could be found (are you missing a using directive or an assembly reference?)

Grid Setup

Good morning,

i need to save column sorting and other filters within a grid.

The only method i figured out is this:

I save the current grid state to the browser local storage

$(window).on("beforeunload", function () {

               var GType = '@Model.flowCatalogId' + '@Model.flowTypeCatalogId' + '@Model.filterVersion' + '@ViewBag.Lang' + '_grid_filtered';
            var grid = $("#grid_filtered").data("kendoGrid");
               localStorage["QSW-grid-Claim-List" + GType] = utf8_to_b64(kendo.stringify(grid.getOptions()));

         })

Then i reload it every time i enter the page at the end of it's load

$(document).ready(function () {

        $('body').css('pointer-events', 'all') //activate all pointer-events on body
        $('#dialog_pos').data("kendoDialog").close();
        $('#dialog_pos_supp').data("kendoDialog").close();
        $('#dialog_create').data("kendoDialog").close();

        var GType = '@Model.flowCatalogId' + '@Model.flowTypeCatalogId' + '@Model.filterVersion' + '@ViewBag.Lang' + '_grid_filtered';
        var grid = $("#grid_filtered").data("kendoGrid");

        if (localStorage["QSW-grid-Claim-List" + GType]) {
            var options = b64_to_utf8(localStorage["QSW-grid-Claim-List" + GType]);
            grid.setOptions(JSON.parse(options));
        }
        else
        {
            for (i = 0; i < localStorage.length; i++) {
                x = localStorage.key(i);
                if (x.includes("QSW")) { localStorage.removeItem(x);}
            }
        }

        $('#btnCreate').click(function (e) {
            $(this).prop('disabled', true);
            $('#create_form').submit();
        });


    });

This works but it do the read function of my grid 2 times.

.Read(read => read.Action("Claims_Read_Filtered", "Claim", new { flowCatalogId = Model.flowCatalogId, flowTypeCatalogId = Model.flowTypeCatalogId, Model.DateFrom, Model.DateTo})

My question is, how can i save the state of the grid with all of its filters and the column sorting and all the eventual changes i've done to it without run the read a second time?
