Step 4

Let’s create a new component. In this article, we are going to see Kendo autocomplete for Angular 2. To use the autocomplete control, first we need to install the Kendo dropdowns module, give the command given below to install the Kendo dropdowns

npm install -S @progress/kendo-angular-dropdowns

Step 5

Create a separate component to organize our Application, use the command given below to install the component.

ng g component dropdown-autocomplete

Check out the figure given below to get the list of the files created to organize our autocomplete component.



The separate dropdown-autocomplete folder is created to maintain out autocomplete component.



Step 5

Open app.module.ts file and add the information of Kendo dropdowns, which are installed.
  1. import { BrowserModule } from '@angular/platform-browser';  
  2. import { NgModule } from '@angular/core';  
  3. import { FormsModule } from '@angular/forms';  
  4. import { HttpModule } from '@angular/http';  
  5. import { DropDownsModule } from '@progress/kendo-angular-dropdowns';  
  6. import { AppComponent } from './app.component';  
  7. import { DropdownAutocompleteComponent } from './dropdown-autocomplete/dropdown-autocomplete.component';  
  8.   
  9. @NgModule({  
  10.   declarations: [  
  11.     AppComponent,  
  12.       DropdownAutocompleteComponent  
  13.   
  14.   ],  
  15.   imports: [  
  16.     BrowserModule,  
  17.     FormsModule,  
  18.       HttpModule,  
  19.       DropDownsModule  
  20.   ],  
  21.   providers: [],  
  22.   bootstrap: [AppComponent]  
  23. })  
  24. export class AppModule { }   

Step 6

Open dropdown-autocomplete.compoenent.html and write the code given below in it 

  1. <h3>Dropdown-AutoComplete</h3>  
  2.   
  3. <kendo-autocomplete  
  4. [data]="countryList"  
  5.             [placeholder]="'e.g. India'"  
  6.              
  7.  ></kendo-autocomplete>   

Step 7

Open dropdown-autocomplete.compoenent.ts and write the code given below in it.

  1. import { Component, OnInit } from '@angular/core';  
  2.   
  3. @Component({  
  4.   selector: 'app-dropdown-autocomplete',  
  5.   templateUrl: './dropdown-autocomplete.component.html',  
  6.   styleUrls: ['./dropdown-autocomplete.component.scss']  
  7. })  
  8. export class DropdownAutocompleteComponent implements OnInit {  
  9.     public countryList: Array<string> = [  
  10.         "India", "China","Australia"]  
  11.   constructor() { }  
  12.   
  13.   ngOnInit() {  
  14.   }  
  15.   
  16. }  

The countrylist array is created, which is used to populate the auto complete control and the selector(app-dropdown-autocomplete) is defined.

Step 8

Open app.component.html file and write the code given below. 

  1. <h1>  
  2.   {{title}}  
  3. </h1>  
  4. <app-dropdown-autocomplete></app-dropdown-autocomplete>   

App.componenent.html is the main page, which is used to display the control based on the selector.

Step 9

Configure the theme

Open the style.scss and write the code given below in it

  1. @import "~@progress/kendo-theme-default/scss/all";   

The code given above is used to integrate Kendo's default theme into our Application.

Step 10
 
Build the application 
 
Give the command given below to build the Application.
 
ng serve

dropdown-autocomplete.compoenent.ts
