Basic Usage

The following example demonstrates the Button, ButtonGroup, DropDownButton, and SplitButton components in action.

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { ButtonsModule } from '@progress/kendo-angular-buttons';
import { AppComponent } from './app.component';

@NgModule({
    bootstrap:    [AppComponent],
    declarations: [AppComponent],
    imports:      [BrowserModule, BrowserAnimationsModule, ButtonsModule]
})
export class AppModule {}

import { Component } from '@angular/core';

@Component({
    selector: 'my-app',
    styles: ['.example-wrapper,.example-col{ vertical-align: top; }'],
    template: `
        <div class="example-wrapper">
            <div class="example-col">
              <p>Button</p>
              <button kendoButton (click)="onButtonClick()">Default</button>
              <button kendoButton (click)="onButtonClick()" [primary]="true">Primary</button>
              <button kendoButton (click)="onButtonClick()" [disabled]="true">Disabled</button>
            </div>
            <div class="example-col">
              <p>ButtonGroup</p>
              <kendo-buttongroup>
                <button kendoButton [toggleable]="true">
                  Option A
                </button>
                <button kendoButton [toggleable]="true">

                </button>
                <button kendoButton [toggleable]="true">
                  Option C
                </button>
              </kendo-buttongroup>
            </div>
            <div class="example-col">
                <p>DropDownButton</p>
                <kendo-dropdownbutton
                    [data]="dropDownButtonItems"
                    [icon]="'cog'"
                    (itemClick)="onSplitButtonItemClick($event)">
                    User Settings
                </kendo-dropdownbutton>
            </div>
            <div class="example-col">
                <p>SplitButton</p>
                <kendo-splitbutton
                    [data]="splitButtonItems"
                    [icon]="'paste'"
                    (itemClick)="onSplitButtonItemClick($event)"
                    (buttonClick)="onSplitButtonClick()">
                    Paste
                </kendo-splitbutton>
            </div>
        </div>
    `
})

export class AppComponent {
    imageUrl = 'https://demos.telerik.com/kendo-ui/content/shared/icons/sports/snowboarding.png';

    splitButtonItems: Array<any> = [{
        text: 'Keep Text Only',
        icon: 'paste-plain-text',
        click: () => { console.log('Keep Text Only click handler'); }
    }, {
        text: 'Paste as HTML',
        icon: 'paste-as-html'
    }, {
        text: 'Paste Markdown',
        icon: 'paste-markdown'
    }, {
        text: 'Set Default Paste'
    }];

    dropDownButtonItems: Array<any> = [{
        text: 'My Profile'
    }, {
        text: 'Friend Requests'
    }, {
        text: 'Account Settings'
    }, {
        text: 'Support'
    }, {
        text: 'Log Out'
    }];

    public onSplitButtonClick(dataItem: any): void {
        console.log('Paste');
    }

    public onSplitButtonItemClick(dataItem: any): void {
        if (dataItem) {
            console.log(dataItem.text);
        }
    }

    onButtonClick() {
        console.log('click');
    }
}

import { AppModule } from './app.module';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

const platform = platformBrowserDynamic();
platform.bootstrapModule(AppModule);

Installation

Either use the quick setup (Angular CLI v6 or later) or manually add the package (Angular CLI v5 or earlier).

Quick Setup with Angular CLI v6 or Later

Angular CLI v6 supports the addition of packages through the ng add command which executes in one step the set of otherwise individually needed commands.

ng add @progress/kendo-angular-buttons

Manual Setup

All components that you reference during the installation will be present in the final bundle of your application. To avoid ending up with components you do not actually need, either:

  • Import all Buttons components at once by using the ButtonsModule, or

  • Import a specific Buttons component by adding it as an individual NgModule.

  1. Download and install the package.

    npm install --save @progress/kendo-angular-buttons @progress/kendo-angular-l10n

  2. For Angular 6, install the rxjs-compat package. For more information, refer to the article on upgrading to Angular 6.

    npm install --save rxjs-compat@6

    For Angular 5 or earlier, install RxJS v5.5+.

    npm install --save rxjs@^5.5

  3. Once installed, import the NgModule of the components you need.

    To get all package components, import the ButtonsModule in your application root or feature module.

    import { NgModule } from '@angular/core';
   import { BrowserModule } from '@angular/platform-browser';
   import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
   import { ButtonsModule } from '@progress/kendo-angular-buttons';
   import { AppComponent } from './app.component';

   @NgModule({
       bootstrap:    [AppComponent],
       declarations: [AppComponent],
       imports:      [BrowserModule, BrowserAnimationsModule, ButtonsModule]
   })
   export class AppModule {
   }

    The package also exports the following modules for individual components:

    • ButtonModule
    • ButtonGroupModule
    • DropDownButtonModule
    • SplitButtonModule

    To reduce the size of your application, include only the modules you need.

    import { NgModule } from '@angular/core';
   import { BrowserModule } from '@angular/platform-browser';
   import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
   import { AppComponent } from './app.component';

   // Imports the Button module
   import { ButtonModule } from '@progress/kendo-angular-buttons';

   // Imports the ButtonGroup module
   import { ButtonGroupModule } from '@progress/kendo-angular-buttons';

   @NgModule({
       bootstrap:    [AppComponent],
       declarations: [AppComponent],
       imports:      [
           BrowserModule, BrowserAnimationsModule,
           ButtonModule, ButtonGroupModule
       ]
   })
   export class AppModule {
   }

  4. You are required to install one of the Kendo UI themes for Angular to style your components. For more information on how to add the styles, refer to the section on styling.

Dependencies

The Buttons package requires you to install the following peer dependencies in your application:

  • @angular/common
  • @angular/core
  • @progress/kendo-angular-l10n
  • rxjs

The following dependencies are automatically installed:

  • @progress/kendo-angular-popup

The Buttons package utilizes the Angular animation system, which supports a specific set of browsers.
