Is it possible to alter the format of the expressionPreview?

When a date filter is applied, the preview looks like: "Date Is After 'Tue Jan 01 2019 00:00:00 GMT+0000 (Greenwich Mean Time)'" -- I'd like to be able to customize the displayed date format, something like adding "format:"{0:dd/MM/yyyy}" to the 'fields' object.

Thanks

Row hover action bar

Hi,

I'm looking to implement an "action bar" when a user mouse hover a row. Just like in gmail or outlook365 when a user mouse is hover a message, icons appear to delete, mark as read, ...

All I found as of now, is to reserve a column and with jquery/css show/hide the icons. I don't want to reserve a specific column for that. I want it to be on either at the beginning (left) or at the end (right) of a row and on top of the row. I attached an image to demonstrate what I want to do.

An ideas ?

Thanks

Forcing column width for narrow grids

In the column width page of the grid documentation https://docs.telerik.com/kendo-ui/controls/data-management/grid/columns/widths, it says:

When scrolling is enabled:

- When all columns have pixel widths and their sum is less than the width of the Grid, the column widths are ignored and the browser expands all columns.

Is there a way to disable that for certain columns? Some of my columns - especially the command column - look really stupid when the auto-resizing adds a bunch of whitespace to them.

Multiselect with checkbox.

Good morning I have to realize multiselect with checkbox.
The final result will be very similar to this:
http://embed.plnkr.co/OVPTCV/
This example, however, is very old and I noticed that with the 2018 version of kendo it does not work perfectly.
It is possible to have the same result using the version of kendo 2018 which seems to me to use different approaches. (eg tagtemplate)

Translation single tag mode.

When using tagMode single, text appears how many items are selected. (2 item(s) selected).

How can I translate this text. I though that there would be some line in kendo.messages.de/fr ... But it is not.

Sort all-day items by object field

I'm using the scheduler for only all-day items, and would like to sort items based off a given field (in this case a C# long value).

How would I go about doing this?
This is my current code:

@{

ViewBag.Title = $"Profile Calendar";

}

<style>

/* increase the height of the cells in day, work week and week views */

.k-scheduler-table td,

.k-scheduler-table th {

height: 1em;

}

/* The following styles will work only with Kendo UI versions before 2020 R1 */

/* increase the height of the month view cells */

.k-scheduler-monthview .k-scheduler-table td {

height: 20em;

}

.k-event-template {

font-size: 0.75em;

width: 125px;

white-space: nowrap;

overflow: hidden;

text-overflow: ellipsis;

}

</style>

<h2>@ViewBag.Title</h2>

<div id="scheduler"></div>

<script>

$(function() {

$("#scheduler").kendoScheduler({

change: function(e) {

var start = e.start;

var end = e.end;

console.log(kendo.format("Selection between {0:g} and {1:g}", start, end));

},

edit: function(e) {

e.preventDefault(true);

window.location.href = "@Url.Action("View", "Profile")?id=" + e.event.ProfileId;

},

views: [

{ type: "month", selected: true},

{ type: "day"},

],

resources: [{

dataSource: {

transport: {

read: {

url: "@Url.Action("ListAll", "Lab")"

}

},

schema: {

model: {

id: "Id",

fields: {

Id: {

"type": "number"

},

ProfileId: {

"type": "number"

},

Name: {

"type": "string"

},

DisplayColor: {

"type": "string"

}

},

title: "Lab",

field: "LabId",

dataTextField: "Name",

dataValueField: "Id",

dataColorField: "DisplayColor"

}],

dataSource: {

transport: {

read: {

url: "@Url.Action("List", "Calendar")",

dataType: "json",

contentType: "application/json; charset=utf-8",

type: "POST"

},

parameterMap: function (options, operation) {

if (operation === "read") {

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

var result = {

start: scheduler.view().startDate(),

end: scheduler.view().endDate()

}

return kendo.stringify(result);

}

return kendo.stringify(options);

}

},

serverFiltering: true,

schema: {

model: {

id: "taskID",

fields: {

taskID: { from: "TaskID", type: "number" },

title: { from: "Title", defaultValue: "No title", validation: { required: true } },

start: { type: "date", from: "Start" },

end: { type: "date", from: "End" },

startTimezone: { from: "StartTimezone" },

endTimezone: { from: "EndTimezone" },

description: { from: "Description" },

recurrenceId: { from: "RecurrenceID" },

recurrenceRule: { from: "RecurrenceRule" },

recurrenceException: { from: "RecurrenceException" },

ownerId: { from: "OwnerID", defaultValue: 1 },

isAllDay: { type: "boolean", from: "IsAllDay" },

LabId: { from: "LabId", type: "number" },

ProfileId: { from: "ProfileId", type: "number" }

}

});

</script>

The field I want to sort by is LabId, which is a long.

Additionally, if there was a way to do this in MVC instead, greatly appreciated. With the inclusions of resources, I had trouble doing it in MVC.

Set Marker Backgrounds to Match Stroke Color

Hi, I've been trying to figure out a way to make the markers on my scatter chart solid. It'd be nice if there was a prop for this.

I am able to set the color with a function, but that only sets the stroke color. I can set the background in the marker props, but that doesn't take a function so some of my points don't have a matching background to stroke.

Grid with Json Variable and Schema

Hi All,

I have a js variable JSON_DATA that contains the return result from a .py api. It has a schema 'xyz' and 5 columns (a,b,c,d,e). I've tried to setup the the schema and datasource several different ways and I can't seem to get it to bind the data. Can someone shed some light on this for me? See below:

This is where I'm at now, I removed schema to see if I could get something back but I'm stuck:

\$(document).ready(function() {
\$("#grid").kendoGrid({
dataSource: {
data: $JSON_DATA },
height: 550,
scrollable: true,
sortable: true,
filterable: true,
pageable: {
input: true,
numeric: false
},
columns: [
{ field: 'productType', title: 'CSS-WX Product Type', width: '230px'},
{ field: 'serviceType', title: 'Web Service Type', width: '100px'},
{ field: 'average', title: 'Average', width: '130px' },
{ field: 'target', title: 'Target', width: '130px' },
{ field: 'iterations', title: 'Iterations', width: '130px' }
]
});
});
