Aspect Ratio for ImageEditor

Hi,

We would like to force the user to crop the image in a 4:3 aspect ratio only.

this._kendoImageEditor = $("#kendoImageEditorComponent").kendoImageEditor({

imageUrl: options.image,

toolbar:{

items:

[

"zoomIn",

"zoomOut",

"crop"

]

},

messages: {

panes: {

crop: {

aspectRatioItems: {

"4:3": "4:3"

}

}).data("kendoImageEditor");

However when testing we see all the other aspect ratios.

Can these be removed?

Multiple days event

Hi, if you add an event that starts 08/17/2015 8:00AM and ends at 08/19/2015 : 8h00PM, the scheduler will display the item as if it was an all day event for all three days which is not visually useful.

I would like to be able to show the event starting at 8h00AM the first day all the way down to the end of the day, then the second day shown as an all day item and finally have the event continue on the last day from 12:00AM to 8h00PM.

Is there a way to achieve this with the scheduler?

(I attached some screenshots to better explain my requirements)

How do you make the star icons smaller?

We're using the jQuery rating with Bootstrap theme. The default star icons are huge. How do you make them look smaller and with less spacing in between? I tried using css to override the font-size but it gets weird when you have half precision values. The half stars look shifted.

Unable to add header cells in spreadsheet binded to datasource

Hello everyone,

I am using Kendo 2020.2.513 and I want to do something as in this Dojo: https://dojo.telerik.com/EnuyodAQ

In fact, I am perfectly able to reproduce that code in my project. However, as soon as I change the URL with the one that is providing my data, the code is failing. Data is binded correctly to the spreadsheet, but the next error occurs:

kendo.all.js:139181 Uncaught Error: Shifting nonblank cells off the worksheet is not supported!

at init.insertRow (kendo.all.js:139181)

I have even updated the server code to return provide a Jsonp output (so far, it was normal Json). When accessing the data URL directly, with a callback query parameter, the output is consistent with the one in the Dojo example (https://demos.telerik.com/kendo-ui/service/Products?callback=someCallbackFn&_=1234).

The only difference I can come up with is that, since I am testing locally, my server is serving the content without SSL/TLS (no HTTPS). But I don't think that is relevant at this point.

Do you have any idea of what can be going on?

Responsive Layout Container

For the past few months, I have been experimenting with React and Material UI and put one very simple application into production.

I am working on my second app which will be an online membership application. It will need masked inputs for things such as dates, SSN# and credit cards. This is where Mui started to fall short. My company already licenses the DevCraft bundle for a WPF project so I started digging into Kendo. It has all the controls I need and others I didn't even thinks of using.

My initial question isn't about the controls, but to point me in a direction for best practices responsive layout containers. Mui has Grid (not to be confused with a Data Grid), boxes and Container which helps with that.

It's not clear to me how you do this with Kendo. Do you have any articles to share.

Thanks

Anthony

Donut chart with curved series name?

I know the original thread got moved to the Feedback Portal, but just in case someone else is looking for a way to do this until it is provided by kendo. When the thread got moved to the portal, this was added: Note: DOM manipulation over SVG elements is not a great approach, and I would not recommend it, unless it is absolutely unavoidable. Unfortunately, there is nothing more reasonable that can be done instead.

Here is a dojo and here is the code:

<!DOCTYPE html>

<html>

<head>

<base href="https://demos.telerik.com/kendo-ui/donut-charts/index">

<style>html { font-size: 14px; font-family: Arial, Helvetica, sans-serif; }</style>

Inline Editing with Float Values

So this is a bit of a strange one. Have a database where items are stored in float due to the variance of the decimal points. So you will commonly find scientific notation (7e-8 for example). I am using Inline Editing on the grid and have use this to display the number as a decimal:

{
                field: "testValue",
                title: "Value",
                width: 100,
                editor: customNumberEditor,
                template: "#= kendo.toString(testValue, 'n' + schemeNomRes)#"
}

However, when you click the Edit Button in the row. The text field reverts back to Scientific Notation. My function for customNumberEditor is pretty basic:

function customNumberEditor(container, options) {
$("<input required name=\"" + options.field + "\" onkeypress= \"return isNumber(event)\">").appendTo(container);
}

Is there something I could do there to ensure that the number appears in my textbox as: 0.00000008 in this example?

Thanks,

Richard

Search box kendo grid

I'm trying to create a simple search box that will search in all the fields found within the grid.

I tried using the filterable option to get a search box. But I ended up getting search box/operators for every single column. All I want is a single search box in my grid that searches through all columns/fields. How can I do this? Also I setting the showOperators false for specific columns didn't work for me. The operators are always visible.

I can post additional code if necessary but it's out of context for the problem I'm experiencing.

<p></p><p>filterable: {<br> mode: 'row',<br> showOperators: false<br>}</p>
