The following example illustrates how to show selected state on initial render.
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
template: `<!-- To render ButtonGroup. -->
<div class='e-btn-group'>
<input type="checkbox" id="checkbold" name="font" value="bold" checked/>
<label class="e-btn" for="checkbold">Bold</label>
<input type="checkbox" id="checkitalic" name="font" value="italic" />
<label class="e-btn" for="checkitalic">Italic</label>
<input type="checkbox" id="checkline" name="font" value="underline"/>
<label class="e-btn" for="checkline">Underline</label>
</div>`
})
export class AppComponent { }import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ButtonModule } from '@syncfusion/ej2-angular-buttons';
import { AppComponent } from './app.component';
import { enableRipple } from '@syncfusion/ej2-base';
enableRipple(true);
/**
* Module
*/
@NgModule({
imports: [
BrowserModule,
ButtonModule
],
declarations: [AppComponent],
bootstrap: [AppComponent]
})
export class AppModule { }import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
