• The grid fires all "read", "create", "update" and "destroy" action methods from the controller when I use: "kendo.data.GanttDataSource" but when I use "kendo.data.DataSource", the grid only fires "read".
• When I hit "Add new record" button and fill all the details, one corresponding create action method is fired (which is successful) but also fires multiple failed update action method (the number of these fires is equal to number of rows in the grid)
• When I hit delete, Delete event is triggered for all the records thus making my grid empty.

<script>
    $(document).ready(function () {
        var datasource = new kendo.data.GanttDataSource({

Hi,

I recently upgraded our apps to latest kendo UI version and one of things we had implemented is broken: 

Collapse/expand gantt list to a certain level (for example I want only first or first two levels to be expanded).

Before we used data-level property that was part of gantt list, but it seems that with R3 2020 since gantt custom list was replaced with a treelist this is gone.

Was this property removed by accident or it is intentional? If it was intentional, could you advice on new approach.

I would like avoid iterating through all elements and finding structure, since we have cases where projects have a lot of elements and also some other conditions included.

Thanks

Hi,

while reading other threads, i got to know that Kendo doesnt support sticky column on the right hand side, but is there a way to achieve this?

I am using something similar to command bar as the last visible column in the grid, but i need it to be sticky when i horizontally scroll the grid. 

can you please suggest a way to achieve this?

Thanks,

Hi,  I am using cascading dropdown list and trying to pass a parameter to the function that I am calling to get the data from DB. Below is my code, whenever this function is called it passes NULL. Anyone has any idea why?

var categories = $("#categories").kendoDropDownList({
                        optionLabel: "Select category...",
                        dataTextField: "CategoryName",
                        dataValueField: "CategoryID",
                        dataSource: {
                            type: "odata",
                            serverFiltering: true,
                            transport: {
                                read: {
                                url: '@Url.Action("Getcategories")',

                                contentType: "application/json",
                                type: "GET"
                            }
                            }
                        }
                    }).data("kendoDropDownList");

                    var products = $("#products").kendoDropDownList({
                        autoBind: false,
                        cascadeFrom: "categories",
                        optionLabel: "Select product...",
                        dataTextField: "ProductName",
                        dataValueField: "ProductID",

I created a kendo map and i'm using a openstreetmap, I also created a layer shape polygon with my coordinates but when I zoom, my shape disappears and I don't know why.

Maybe it is because my shape is not very large (about 1hectare).

I tried with more coordinates (about 100) but it is the same thing.

Should i change the map or just kendo can't zoom on little shape ?

This is my map with zoom 13 :

And with zoom 14, my shape disappears.

My code :

<script>
    $("#map").kendoMap({
   
             center: [48.471504, - 2.457585],
                zoom: 13,
                layers: [{
                    type: "tile",
                   urlTemplate: "http://#= subdomain #.tile.openstreetmap.org/#= zoom #/#= x #/#= y #.png",
            subdomains: ["a", "b", "c"]
                }, {
                    extent: [
                        48.499924, - 2.459692,
                        48.45, -2.479
                    ],
                    minZoom: 11,
                    type: "shape",
                    style: {
                        fill: {
                            opacity: 0
                        },
                        stroke: {
                            color: "red",
                            width: 2
                        }
                    },
                    dataSource: {
                        type: "geojson",
                        data: [{
                            "type": "Polygon",
                            "coordinates": [[ listCoordinates                        
                            ]]
                        }]
                    }
                }]
            });
</script>

How can i zoom and see my shape ?

Hey!

I'm trying to update kendo-ui version to the latest. The initialization code stays the same:

import '@progress/kendo-ui/css/web/kendo.common.less'
import '@progress/kendo-ui/css/web/kendo.default.less'

require('@progress/kendo-ui/js/kendo.all');

It works fine until the version 2020.2.512. Starting from this version and higher "window.kendo" object is still available but jQuery does not contain any of kendo* methods (like $(...).kendoNotification)

So...what changed there?...

I'm using webpack to build the application, jQuery is the latest 3.*

~upd

window.kendo.jQuery has everything in place. But window.jQuery does not

1. Enable serverPaging, serverSorting, virtual scroll. Please refer the attached codes.
2. Run the page in browser.
3. Drag scrollbar to end
   
4. Click "name" column header to sort the grid.

Observed:

Grid only shows the last 3 rows.

Question:

How can I make last ten rows show after sort? Like this:

<html>
	<head>

		<link rel="stylesheet" href="styles/kendo.common.min.css"/>
		<link rel="stylesheet" href="styles/kendo.default.min.css"/>

		<script src="jquery-3.6.0.js"></script>
		<script src="kendo.all.js"></script>

		<style>
			.grid {
				width: 800px;
				height: 400px;
			}
		</style>
	</head>
	<body>
		<div class="grid"></div>
<script>
	$(()=>{
	var ds = [];
	for(var i=0;i<13;i++){
		ds[i]={name:i.toString(),number:i};
	}

	var dataSource = new kendo.data.DataSource({
		serverPaging:true,
		serverSorting:true,
		pageSize:10,
		type: "odata",
		transport: {
			read: options=>{
				var d=[];
				for(var i =options.data.skip;i<options.data.skip+options.data.take && i<ds.length;i++){
					d.push(ds[i]);
				}

				var r = {
					d: {
						__count: ds.length,
						results: d
					}
				};

				options.success(r);
			}
		}
	});

	$(".grid").kendoGrid(
		{
			sortable:true,
			columns:["name","number"],
			dataSource:dataSource,
			scrollable: {
				virtual: true
			}
		}
	);
});
</script>
	</body>
</html>

I'm running into a situation in my MVC app where the Kendo grid seems to be assuming that my date columns are UTC dates and are converting them to local time. Most of my dates are off by one day. 

First of all, is this what the grid is doing? Past posts about issues like this seems to confirm it. If so, can I tell the Kendo grid that my dates are not UTC? We're building an app around an existing database where the dates are not stored as UTC and the dates cannot be converted. If I can't tell the Kendo grid to stop doing this, what alternatives do I have? I know I can represent dates as strings in the grid, but then I lost the ability to sort correctly if the user chooses to sort a date column. Converting all date columns in our database to UTC is not an option.
