We need your feedback, because we are considering
changes in the release approach for Kendo UI for jQuery. Please provide
your feedback in the comments section below:
1. Is it hard to understand the version numbers of our releases? If yes, what makes them hard to understand them?
2. Would semantic versioning (SemVer) of our releases make it easier to understand our version numbers and what's behind them?
3. If we go with SemVer, we might need to start with version 3000.0.0 as we currently use 2022.x.x. Please share your thoughts about this approach and ideas for what number versioning would work best for you.

Module Bundlers - Kendo UI Third-Party Tools - Kendo UI for jQuery
The module bundlers page references Vite as an example which leads me to believe that it can be used with Kendo.
However even this basic example doesn't appear to work: https://stackblitz.com/edit/vitejs-vite-i842ucun?file=src%2Fmain.js
Am I doing something wrong?

I'm using Kendo UI for jquery to show a grid in a bootstrap modal window.
The grid has column header filters, but the user cannot input text in the filter.
You can test this issue using this example:
https://dojo.telerik.com/ESmbjbbT/4
The full example code is:
<!DOCTYPE html>
<html>
<head>
<base href="https://demos.telerik.com/kendo-ui/grid/filter-row">
<style>html { font-size: 14px; font-family: Arial, Helvetica, sans-serif; }</style>
<title></title>
<link href="https://kendo.cdn.telerik.com/themes/10.2.0/default/default-main.css" rel="stylesheet" />
<script src="https://code.jquery.com/jquery-3.7.0.min.js"></script>

Hello.
We own a license for an older version of Kendo UI for jQuery, and we are now testing the latest release (demo version) to decide if we should upgrade.
We have a chart showing the datapoints from a datasource, where category is a date (rounded to minute) and value is a number. Series is set to show a gap if data point is missing.
The attached picture shows the chart on the left, and the content of the datasource._view array as logged in the browser's JavaScript console. As you can see after datapoint at 15.57 there's a big gap, even if the datapoints actually exist in the datasource.
The chart is updated by creating a new datasource when new data is available every 5 minutes.
What could be the reason if such behavior? Are we doing something wrong? Maybe we should reset the chart in some way before passing the updated datasource?
Thank you.

Hello.
We own a license for an older version of Kendo UI for jQuery, and we are now testing the latest release (demo version) to decide if we should upgrade.
We have implemented a light/dark/auto mode switch for our application. For Kendo theme, this is achieved by changing the name of the css loaded by the page.
Everything works fine for all widgets except charts. When mode is changed, for example switching from light to dark, all axis labels, lines, background, etc stay the same (light theme). If the page is reloaded (and chart recreated), then the correct mode is applied.
Attached you will find three images showing the behavior: initial light mode, after switch to dark mode, after page reload.
Given for our application reloading the page is not an option, is there a fix or workaround for this behavior?
Calling the redraw method doesn't help.
Thank you.

I'm trying to add series to a specific axis when users drag an item from a treeview and drop it over some axis.
To implement this scenario, is necessary to know the index of the droped axis.
There is any event that I can subscribe to get axis mouse drop?
Regards,
Gustavo

Hello,
Here is my validator code:
<script type="application/javascript">
$(document).ready(function () {
console.log("Ready");
// Initialize Kendo MaskedTextBox for Phone Number
$("#PhoneNumber").kendoMaskedTextBox({
mask: "000-000-0000"
});
// Set up Kendo Validator with a custom rule
validator =
$(".k-edit-form-container").kendoValidator({
rules: {
phoneMaskRule: function (input) {
// Check if it is the PhoneNumber input and the value matches the mask
if (input.attr("name") === "PhoneNumber") {
var maskedInput = input.data("kendoMaskedTextBox");
// The masked textbox's `raw()` method gets the actual value without placeholder characters
// Checking that it has a complete value (no _ symbols in "raw" value)
var retVal = maskedInput && maskedInput.value() && maskedInput.raw().length === 10;
return retVal;
}
return true; // Let other fields validate as normal
},
nameValidation: function (input) {
// Check for FirstName and LastName validation
if (input.is("[name=UserFirstName]") || input.is("[name=UserLastName]")) {
var retVal = input.val().length > 2; //Ensure there is at least 2 characters in each name.
console.log("Name: " +
(retVal ? "Passed" : "Failed"));
return retVal;
}
return true; // No other inputs are affected by this rule
},
emailFormatValidation: function (input) {
// Check for Email validation
if (input.is("[name=Email]")) {
// Regex for a basic email validation
var emailRegex =/^[a-zA-Z0-9._%+-]+@@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/;
var retVal = emailRegex.test(input.val());
console.log("email: " +
(retVal ? "Passed" : "Failed"));
return retVal
}
return true; // Other inputs are skipped
}
},
messages: {
phoneMaskRule: "Please enter a valid phone number in the format 999-999-9999.",
nameValidation: "First and Last Name must have at least 3 characters.",
emailFormatValidation: "Please enter a valid email address."
}
}).data("kendoValidator");
});
</script>
This validates the user input and usually works correctly. Once data is entered, I check the validator before submitting:
function submitClinic() {
resetInactivityTimer(duration);
if (model == null) {
model = {};
model.ClinicUserID = "";
}
// Check if form is valid
if (!$(".k-edit-form-container").kendoValidator().data("kendoValidator").validate())
{
return false; // not valid
}...
}
So for some reason, the validator starts returning "not valid" out of the blue. I can click through the form and see that the validator validates the fields correctly, but I press my submit button, and suddenly it claims the fields fail
I thought maybe the validator object is null, but it's clearly calling the validation functions, but for some reason it fails? Any suggestions would be very helpful.
Thanks!
