[Solved] 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?

[Solved] 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?

Column editor with opportunities to add new record and select from existing ones

I need an editor for the field of text type. This editor when is activated should show two buttons. When the first button with the plus icon is clicked, an input appears in which a new value is typed. When the button with a colon is clicked, a dropdown appears from which an existing value is selected.

My template is

<div>
<partial name="EditorTemplates/WorkingEmployeeEditorTemplate"/>
<div style="margin: 15px; display: inline-block;">
@(Html.Kendo().Button()
.Name("createButton")
.Content("Add")
// .Events(e => { e.Click("create"); })
 )
</div>

It should have the dropdown and button in one row. When I rerun the page with this template, the grid disappears.
