Forms are what we use every day and if there's a form, we often have to validate the input and show the validation results to the user.

Problems:

• The way to do this today with angular requires a lot of code (see https://angular.io/guide/form-validation for examples)
• In many cases we have to handle and show the same validation errors over and over again. E.g. "this field is required"

Opportunity:

• The way validation errors are shown is similar in most applications and can be easily adjusted using simple CSS.
• Common validation error messages should be ok for many applications.

Feature request:

• Add a component to easily display validation errors of form components.
• Add global validation settings to customize standard error messages and behavior.

Example:

// global setup
validationService.configure({
  showIf: 'touchedOrDirty',
  messages: {
   required: "This field is required',
   customKey: 'This field needs ... ',
   customKey2: errorMessageForCustomKey2Fn
});

// callback to generated error message for customKey2
function errorMessageForCustomKey2Fn(control: FormControl)  => return `can include 'but is ... ' from form control`;

// HTML in component template
<input formControlName="myinput" ... />
<validation-errors forControlName="myinput"> // < should handle all globally registered errors without additional code.
  <error key="keyOfValidatorOnlyUsedHere">Sorry, but you have to</error>
</validation-errors>

I think such a feature could massively reduce the work to setup forms.

Hi,

We encountered a problem when using kendo-sortable component in IE11. If we use this component anywhere on the page, all input fields on the page become unclickable. It seems to happen in the last version of this control (maybe because of a global click event listener? )

Hope you can help with this issue.

You can check out the following Stackblitz example which is based on your basic usage example: https://angular-t7vi5k.stackblitz.io/

Thanks in advance and happy holidays,

I want to filter the scheduler data but I had to add the OwnerId property to the node package interface in order to be able to do so... yet the sample data provided in the examples does include the ownerId, so im guessing all that needs to be done is to add it to the interface.

On grid with 50 rows and 100 columns, autoFitColumns method freezes browser and annoying "Page unresponsive" is shown to the user. Please make function responsive.

Based on high Chrome CPU usage I think method could be ran in background thread. Probably Web workers would be appropriate for this task. This may help.

The example does not work:

Is it possible to add a duration input control in format HH.  I´m not talking about a time picker, but a way to choose how much time will last doing something.

The value could be in minutes or hours (fractional minutes).

Here is a discussion on this topic on

When both virtual scrolling and grouping are enabled via the kendoGridGroupBinding directive, and the Grid is navigable, focus is trapped in the header row when down or up arrow is pressed:

https://stackblitz.com/edit/angular-icxejq?file=app/app.component.ts

1. Focus any content cell

2. Press up/down - focus goes to the header cell of the respective column and is trapped in the header row

I requested help in the Forum for an example of using JSDO in a Service under Angular for my grid.component.ts

https://www.telerik.com/forums/angular-7-kendo-grid-using-jsdo-service-component

Svetlin stated thet "Indeed, currently we do not have an example dedicated on the use of CRUD operations with JSDO. If you have the time, please submit a new feature request in our UserVoice portal, which will help us to evaluate the demand for such example and implement it in the future. "

Please look into building some sample source for an Angular / JSDO Service component.

Thanks

On a feedback portal search and paging is not working.

Open feedback portal and enter search criteria with more then five item. example

When you want to view result for second page, search is not preserved (it is empty).

The fromDate method of the kendo-intl package allows to use a skeleton format to provide a generic mask that is applied to the current locale.
It would be great to get this functionality for the format string of the date-inputs to gain the possibility to define a locale independent format.
E.g yMMMM will show year and month with respect to the current locale.

To change the topView or bottomView property I have to set the value as string. E.g. topView="month". To be typesave I like to use the CalendarViewEnum in my typescript code. When I bind the enum in the view, the enum-value is set.
But unfortunately the enum value is a number and not a string.
I must convert the enum value like:

public getBottomView(): string {
     return CalendarViewEnum[this._bottomView];
}

Live would be easier if string enums would be used.

Please add support to the @progress/kendo-angular-intl library for the following Norwegian locales:

Norwegian, Nynorsk (Norway)
Sami (Northern) (Norway)
Sami (Southern) (Norway)
Sami (Lule) (Norway)

Could you please migrate Kendo UI Spreadsheet from jQuery version to Angular?

It'll be awesome if you can have required packages in the package.json file in StackBlitz based on sample. An example, If I'm looking at Kendo Menu sample code in StackBlitz I can just go to package.json and see all the required packages I need to work with Kendo Menu.

Regarding not only DateTime Pickers, but Data Query in general, it would be great if you could offer the option to automatically remove the time offset in OData path.
Please find an example below:
We need to retrieve all data concerning the date "2000-01-01".
Data are stored as shown below:
Date1:	"2000-01-01T00:00:00+02:00"
Date2:	"2000-01-01T00:00:00+03:00"
The OData path constructed is the following:
"... or cfTrade/TradeDate eq 2000-01-01T00:00:00.000Z..."
So, no Date is actually retrieved.
