Kendo UI makes it potential to go from a primary thought to a full-fledged app, thanks to an enormous element library. We’re speaking properly over 100 elements which might be prepared so that you can drop into your app at will, whether or not it’s React, Angular or Vue you’re working in — they simply work. That’s as a result of Kendo UI is definitely a bundle of 4 JavaScript libraries, every constructed natively for his or her respective framework. However greater than that, as we’ve lined earlier than, the elements are tremendous themeable to the extent which you could make them no matter you need.
However right here’s the true kicker with Kendo UI: it takes care of the heavy lifting. The styling is nice and all, however what separates Kendo UI from different element frameworks is the performance it gives proper out of the field.
Living proof: knowledge. Moderately than spending all of your time determining one of the simplest ways to bind knowledge to a element, that’s only a given which finally lets you focus extra of your time on theming and getting the UI excellent.
Maybe one of the simplest ways to see how trivial Kendo UI makes working with knowledge is to see it in motion, so…
Let’s take a look at the Angular Grid element
That is the Kendo UI for Angular Information Grid element. A lot of knowledge in there, proper? We’re taking a look at an inventory of workers that shows a reputation, picture, and different bits of details about every particular person.
Like all of Kendo UI’s elements, it’s not like there’s one knowledge grid element that they square-pegged to work in a number of frameworks. This knowledge grid was constructed from scratch and designed particularly to work for Angular, simply as their KendoReact Grid element is designed particularly for React.
Now, usually, a easy <desk> component may do the trick, proper? However Kendo UI for Angular’s knowledge grid is chockfull of extras that make it a significantly better consumer expertise. Discover proper off the bat that it gives interactive performance round issues like exporting the information to Excel or PDF. And there are a bunch of different non-trivial options that might in any other case take a overwhelming majority of the effort and time to make the element.
Filtering
Right here’s one for you: filtering a grid of knowledge. Say you’re taking a look at an inventory of workers like the information grid instance above, however for a corporation that workers 1000’s of parents. It’d be laborious to discover a particular particular person with out contemplating a slew of options, like search, sortable columns, and pagination — all of which Kendo UI’s knowledge grid does.
Customers can shortly parse the information certain to the Angular knowledge grid. Filtering might be achieved by a devoted filter row, or by a filter menu that pops up when clicking on a filter icon within the header of a column.
One method to filter the information is to click on on a column header, choose the Filter choice, and set the factors.
Kendo UI’s documentation is nice. Right here’s how briskly we will get this up and working.
First, import the element
No methods right here — import the information grid as you’ll some other element:
import { Element, OnInit, ViewChild } from ‘@angular/core’;
import { DataBindingDirective } from ‘@progress/kendo-angular-grid’;
import { course of } from ‘@progress/kendo-data-query’;
import { workers } from ‘./workers’;
import { photos } from ‘./photos’;
Subsequent, name the element
@Element({
selector: ‘my-app’,
template: `
<kendo-grid>
// …
</kendo-grid>
`
})
That is incomplete, in fact, as a result of subsequent now we have to…
Configure the element
The important thing characteristic we need to allow is filtering, however Kendo’s Angular Grid takes all types of characteristic parameters that may be enabled in a single fell swoop, from sorting and grouping, to pagination and virtualization, to call a couple of.
Filtering? It’s a one-liner to bind it to the column headers.
@Element({
selector: ‘my-app’,
template: `
<kendo-grid
[kendoGridBinding]=”gridView”
kendoGridSelectBy=”id”
[selectedKeys]=”mySelection”
[pageSize]=”20″
[pageable]=”true”
[sortable]=”true”
[groupable]=”true”
[reorderable]=”true”
[resizable]=”true”
[height]=”500″
[columnMenu]=”{ filter: true }”
>
// and so forth.
</kendo-grid>
`
})
Then, mark up the remainder of the UI
We gained’t go deep right here. Kendo UI’s documentation has a superb instance of how that appears. This can be a good time to work on the styling as properly, which is completed in a types parameter. Once more, theming a Kendo UI element is a cinch.
To date, now we have a nice-looking knowledge grid earlier than we even plug any precise knowledge into it!
And, lastly, bind the information
You will have observed immediately once we imported the element that we imported “worker” knowledge within the course of. We have to bind that knowledge to the element. Now, that is the place somebody like me would go run off in a nook and cry, however Kendo UI makes it just a little too simple for that to occur.
// Lively the element on init
export class AppComponent implements OnInit {
// Bind the worker knowledge to the element
@ViewChild(DataBindingDirective) dataBinding: DataBindingDirective;
// Set the grid’s knowledge supply to the worker knowledge file
public gridData: any[] = workers;
// Apply the information supply to the Grid element view
public gridView: any[];
public mySelection: string[] = [];
public ngOnInit(): void {
this.gridView = this.gridData;
}
// Begin processing the information
public onFilter(inputValue: string): void {
this.gridView = course of(this.gridData, {
filter: {
// Set the kind of logic (and/or)
logic: “or”,
// Defining filters and their operators
filters: [
{
field: ‘full_name’,
operator: ‘contains’,
value: inputValue
},
{
field: ‘job_title’,
operator: ‘contains’,
value: inputValue
},
{
field: ‘budget’,
operator: ‘contains’,
value: inputValue
},
{
field: ‘phone’,
operator: ‘contains’,
value: inputValue
},
{
field: ‘address’,
operator: ‘contains’,
value: inputValue
}
],
}
}).knowledge;
this.dataBinding.skip = 0;
}
// …
}
Let’s see that demo once more
That’s a heckuva lot of energy with a minimal quantity of effort. The Kendo UI APIs are intensive and switch even probably the most complicated characteristic lifeless easy.
And we didn’t even get to all the different fantastic goodies that we get with Kendo UI elements. Take accessibility. May you think about all the consideration that wants to enter making a element like this accessible? Like all the different highly effective options we get, Kendo UI tackles accessibility for us as properly, taking up the heavy lifting that goes into making a keyboard-friendly UI that meets WCAG 2.0 Alice requirements and is compliant with Part 508 and WAI-ARIA requirements.
