jQuery Grid Row Template can't escape from the bondage of row.
jQuery Grid Row Template works only in row units.

However, ListView is nice because it allows you to put multiple divs on a single line.

I've done a lot of development with KendoGrid. I want the already created KendoGrid to behave like a ListView.
I need a template like ListView inside a Grid. Is it difficult to make?
Grid and ListView are very similar. I hope that the already developed Grid will be like ListView with a simple template function.
Converting an already developed Grid to a ListView takes too much effort. that's insane It should be resolved in Progress.

Or, is there already a way?

thank you.

JQuery Is Not Defined

Hello,

I recently upgrade my Angular project to Angular 15.

My project uses Kendo-UI for Angular, version 2022.3.1109. I can build the Angular project successfully, however, at runtime I get the following error.

Uncaught ReferenceError: jQuery is not defined
    at Object.<anonymous> (main.js:1:289462)
    at 56426 (main.js:1:4601988)
    at r (runtime.js:1:143)
    at 51403 (main.js:1:207525)
    at r (runtime.js:1:143)
    at Ln (main.js:1:6260043)
    at main.js:1:6260064
    at n (runtime.js:1:2659)
    at main.js:1:69

I have no direct reference to JQuery in my Angular project.

I was able to trace the problem to the following lines of code.

Which comes from kendo.router.js.

Could someone help me understand the problem, it seems like there is an issue with Kendo-UI for Angular, version 2022.3.1109, JQuery is not being properly defined.

By the way, I also attempted to follow the guide Kendo UI for jQuery Integration. Same result.

Any help/tips are appreciated.

Thank you.

Show out of range years in datePicker

In my date picker, I have a range of available dates from 1/1/2022 - 12/31/2024. When I open the date picker and drill back to the years they look out of place because the first three cells which were likely reserved for 2019 - 2021 are blank. 2022 starts in the middle of the picker and 2024 wraps to the next line. There is a feature with the months to display the disabled days using month.empty and passing an HTML string. I don't see anything like that for year though. Is there either a way to show disabled years or to start with the first year in the first cell of the first row?

$("#myDatePicker").kendoDatePicker({
        month: {
            empty: '<span class="k-state-disabled">#= data.value #</span>'
        },
        // I'd like to do something like the below key:year: {
            empty: '<span class="k-state-disabled">#= data.value #</span>'
        },
        dateInput: true,
        start: "month",
        depth: "month",
        min: new Date(2022, 0, 1),
        max: new Date(2024, 11, 31),
        format: "d"
    })

Kendo grid grouping with multi dimensional

Hi,

I'm trying to plot a multi-dimensional data in a kendo grid with grouping.

Here's sample json data:

[
  {
    "category": "Car",
    "name": "Car1",
    "answer": "",
    "subvalues": [      
{
        "category": "4 wheels",
        "name": "4 wheels 1",
        "answer": ""
      },
{
        "category": "4 wheels",
        "name": "4 wheels 2",
        "answer": ""
      },
{
        "category": "6 wheels",
        "name": "6 wheels",
        "answer": ""
      }
]
  },
  {
    "category": "Car",
    "name": "Car 2",
    "answer": "",
    "subvalues": []
  },
  {
    "category": "Truck",
    "name": "Truck 1",
    "answer": "",
    "subvalues": [
{
"category": "4x4",
    "name": "4x4 Truck 1",
    "answer": ""
},
{
"category": "4x2",
    "name": "4x2 Truck 1",
    "answer": ""
}]
  },
  {
    "category": "Truck",
    "name": "Truck 2",
    "answer": "",
    "subvalues": []
  }
]

As you can see, there's a subvalues which is a sub category and I want to group it as well within the same grid.

I'm trying this https://demos.telerik.com/kendo-ui/grid/hierarchy but still no chance.

Thanks everyone!

Uncaught TypeError: $(...).kendoTreeList is not a function

Currently I'm develop hierarchy char by using Kendo UI Treelist feature. Below is my snipe code

in my .aspx file "

I include those scripting in header

<script type="text/javascript" src="../Scripts/jquery-2.1.1.min.js"></script>
<script type="text/javascript" src="../Scripts/kendo/kendo.all.min.js"></script>

in my javascript (datasource is i load from my own data)

var wbsDataSource =

    [{
        ID: "1",
        Description: "Kick Off",
        Parent: null
    }, {
        ID: "2",
        Description: "Meeting",
        Parent: "1"
    }
]

var dataSource = new kendo.data.TreeListDataSource({
    data: wbsDataSource,
    schema: {
        model: {
            id: "ID",
            parentId: "Parent",
            fields: {
                Parent: {
                    field: "Parent",
                    nullable: true
                },
                ID: {
                    field: "ID",
                    type: "number"
                }
            },
            expanded: true
        }
    }
});

$("#treelist").kendoTreeList({
    dataSource: dataSource,
    height: 800,
    editable: {
        move: {
            reorderable: true
        }
    },
    columns: [{
            field: "Description",
            title: "Description",
            width: 280,
        }
    ]

});

however when i run the code above it throw me error "Uncaught TypeError: $(...).kendoTreeList is not a function"

it will only work when I change my html header into code below (JavaScript remain the same), especially with using the base HREF

<base href="https://demos.telerik.com/kendo-ui/treelist/dragdrop">
<style>html { font-size: 14px; font-family: Arial, Helvetica, sans-serif; }</style>
<link rel="stylesheet" href="https://kendo.cdn.telerik.com/2022.3.1109/styles/kendo.default-ocean-blue.min.css" />
<script src="https://kendo.cdn.telerik.com/2023.1.117/js/jquery.min.js"></script>

How to set value for Dropdown properly?

Hi,

i have a dropdown. When the value is set in open event, the value is selected only for the first 16 items (depending on itemHeight in virtual). How do I get the value to always be selected and automatically scroll to the selected value? Below you'll find a running example.

Thanks for your help.
