In our quest to beautify the web, we present more “cool” UI available for the plain & humble Kendo UI button. Kendo UI provides four types of buttons:

1. Button
   You can use Kendo button in your application. To learn how, follow my previous article :
   Beautiful Buttons with Kendo UI in Angular v5 app
   
2. ButtonGroup
   
3. DropDownButton
   
4. SplitButton
   

This post will cover the “ButtonGroup” control.

ButtonGroup

ButtonGroup is a collection of two or more Buttons.  Some features of this:

1. Each button in the ButtonGroup can be separately configured depending on the requirements of your project.
2. You can use any type of button in a ButtonGroup, like Button, Icon Button, or Image Button. Again, it depends on your project requirement.
   
3. Kendo UI ButtonGroup also gives you selection modes. By default, it is Multi-selection with an option to change it into single mode.
   

For using Kendo UI buttons, you need to install Kendo in your Angular application. To learn the process of installation, follow my previous article and make your Angular app ready.

Power up your Angular 5 Application with Kendo UI

When ready with your Angular v5 app along with Kendo UI Buttons module, follow the following process.
Let us use three Kendo buttons in our app like this (output would be like the image):

kendoButton>Yes
kendoButton>No
kendoButton>Cancel

Now, if you need to use ButtonGroup, then write –

as Angular Directive for binding more than one buttons in a group.

kendoButton >Yes
kendoButton >No
kendoButton >Cancel

Now, serve your Angular app with “ng serve –open” again and see the difference in output:

This looks much better as a ButtonGroup.

If you select or click any button, it is not immediately visible  which button was selected. To include this important functionality, you can use toggable property of kendoButton and make it “true”:
[togglable]=“true”

The code now looks like the following:

kendoButton [togglable]=“true”>Yes
kendoButton [togglable]=“true”>No
kendoButton [togglable]=“true”>Cancel

Now, if you click any button in ButtonGroup, it’ll be in selected mode.

Icon buttons in ButtonGroup
Let’s further improve this by including an icon with the button. Here is an example of how you can use Icon button in ButtonGroup:

kendoButton [togglable]=“true” [icon]=“‘check'”>Yes
kendoButton [togglable]=“true” [icon]=“‘cancel'”>No
kendoButton [togglable]=“true” [icon]=“‘close'”>Cancel

The result is much better with visual cues as follows: 

Here are some more icons available for Kendo UI Icon buttons.

Kendo UI ButtonGroup Selection Mode:

Using Selection mode, you can restrict the number of buttons that can be selected in a ButtonGroup. By default, the selection mode of the ButtonGroup is set to multiple. If you want to select one at the time, set selection to single.
[selection]=“‘single'”

Use this code.
<kendo-buttongroup [selection]=“‘single'”>
kendoButton [togglable]=“true” [icon]=“‘check'”>Yes
kendoButton [togglable]=“true” [icon]=“‘cancel'”>No
kendoButton [togglable]=“true” [icon]=“‘close'”>Cancel


Again, serve your Angular App (ng serve –open). Now, user can select only one option at a time.

Disabled ButtonGroup

You can enable or disable the ButtonGroup or an individual button in a ButtonGroup for Angular App.

“disable” is a property for both, ButtonGroup or button. Set “disable” to “true” if you want to disable a ButtonGroup. By default, Kendo UI ButtonGroup sets it to “false” that’s why all the buttons in a group are enabled.

To disable a specific button, set its own disabled attribute to true and leave the disabled attribute of the ButtonGroup undefined. If you define the disabled attribute of the ButtonGroup, it will take precedence over the disabled attributes of the underlying buttons and they will be ignored.

[disabled]=“true”

Example:

Here are two ButtonGroups in which I used “disable” for ButtonGroup level and also for individual button.

<kendo-buttongroup [selection]=“‘single'” [disabled]=“true”>
kendoButton [togglable]=“true” [icon]=“‘check'”>Yes
kendoButton [togglable]=“true” [icon]=“‘cancel'”>No
kendoButton [togglable]=“true” [icon]=“‘close'”>Cancel



<kendo-buttongroup [selection]=“‘single'”>
kendoButton [togglable]=“true” [icon]=“‘check'”>Yes
kendoButton [togglable]=“true” [icon]=“‘cancel'” [disabled]=“true”>No
kendoButton [togglable]=“true” [icon]=“‘close'”>Cancel

Watch the output:

Toggle Disabled

You can toggle “disabled” property at run time using component of Angular app. Edit your “app.component.ts” or any component code file where you want to write the function to toggle disable.

export
class AppComponent {
public isDisabled: boolean = true;
public toggleDisabled(): void {
this.isDisabled = !this.isDisabled;

}

}

Now, create a new kendoButton in the app where you want to bind this function.

<button
kendoButton (click)=“toggleDisabled()” [primary]=“true”>Toggle Disabled

And set [disabled]=“isDisabled” in HTML view. Like:

<kendo-buttongroup [selection]=“‘single'” [disabled]=“isDisabled”>

kendoButton [togglable]=“true” [icon]=“‘check'”>Yes

kendoButton [togglable]=“true” [icon]=“‘cancel'”>No

kendoButton [togglable]=“true” [icon]=“‘close'”>Cancel

<kendo-buttongroup [selection]=“‘single'”>
kendoButton [togglable]=“true” [icon]=“‘check'”>Yes
kendoButton [togglable]=“true” [icon]=“‘cancel'” [disabled]=“isDisabled”>No
kendoButton [togglable]=“true” [icon]=“‘close'”>Cancel

<button
kendoButton (click)=“toggleDisabled()” [primary]=“true”>Toggle Disabled

Click on the button to Disable Toggle.

After clicking on “Toggle to Disabled”, your all disabled ButtonGroups or Buttons will be enabled.

You may have used CSS for styling your buttons. Here is an easy solution to make your application buttons more effective and user-friendly without the hassle of CSS, i.e., Kendo UI Buttons. These buttons provide a clickable UI functionality with arbitrary content.

For using Kendo UI buttons, you need to install Kendo in your Angular application. To learn the process of installation, follow my previous article and make your Angular app ready.

Power Up your Angular 5 Application with Kendo UI

Kendo provides four types of buttons:

1. Button
2. ButtonGroup
3. DropDownButton
4. SplitButton

Example:

To get all the package components, import the ‘ButtonsModule’ in your application root module, like in this code:

imports: [

BrowserModule,

FormsModule,

HttpModule,

// Register the modules

BrowserAnimationsModule,

ButtonsModule

]

The package also exports the following modules for individual components:

• ButtonModule
• ButtonGroupModule
• DropDownButtonModule
• SplitButtonModule

Button:

Button is an Angular directive which detects user interaction and triggers a corresponding event. In Kendo UI Button, we have some wonderful features:

1. Default Button
   

For example, I need to use a button for selecting a file from my local computer, so I can use this button with only text (which is the default type), or with text and icon, or may be with only folder icon without text.

Then, select a button acording to your need :

1. Only Text : <button
   kendoButton>Open</button>
   
2. Text with Icon: <button
   kendoButton [icon]=“‘folder'”>Open</button>
   
3. Only Icon: <button
   kendoButton [icon]=“‘folder'”></button>
   

1. Bare Button
   

you just need to use [look] property of kendo UI Buttons and change it to ‘[look]=bare’.

Examples:

1. Only Text : <button
   kendoButton [look]=“‘bare'”>Open</button>
   
2. Text with Icon: <button
   kendoButton [icon]=“‘folder'” [look]=“‘bare'”>Open</button>
   
3. Only Icon: <button
   kendoButton [icon]=“‘folder'” [look]=“‘bare'”></button>
   

1. Flat Button
   

Again, just change the [look] property to ‘flat’ like ‘ [look]=”‘flat'” ‘. The bare and flat buttons look almost same but select or mouse hover styles are a little bit different.

Examples:

1. Only Text : <button
   kendoButton [look]=“‘flat'”>Open</button>
   
2. Text with Icon: <button
   kendoButton [icon]=“‘folder'” [look]=“‘flat'”>Open</button>
   
3. Only Icon: <button
   kendoButton [icon]=“‘folder'” [look]=“‘flat'”></button>
   

1. Outline Button
   

Outline Button is used to have a button with in-built border style. Change your [look] property to ‘outline’.

Examples:

1. Only Text : <button
   kendoButton [look]=“‘outline'”>Open</button>
   
2. Text with Icon: <button
   kendoButton [icon]=“‘folder'” [look]=” ‘outline'”>Open</button>
   
3. Only Icon: <button
   kendoButton [icon]=“‘folder'” [look]=” ‘outline'”></button>
   

More Features and Functionalities of Kendo UI Buttons:

• Disabled Button
  

To make any button Disabled, set the disabled property to true only.

Examples:

<button
kendoButton [disabled]=“true”>Save</button>

You can use the same property with any type of buttons.

• Icon Button
  

You can create your buttons more user-friendly by adding image, predefined, or custom icons to it. The button provides three properties for it:

1. icon: For using the built-in Kendo UI icons, Like Folder, Open Folder, and more.

   <button
   kendoButton [icon]=“‘calendar'”>Events</button>
   

2. iconClass: Adding FontAwesome and other font icons from required third-party CSS classes, use iconClass property.

   CSS URL

   <link
   rel=“stylesheet”
   href=“https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css&#8221;>
   

   Using in Button
   

   <button
   kendoButton [iconClass]=“‘fa fa-calendar fa fw'”> Events</button>
   

3. imageURL: for using third-party images as icon from a specified URL.
   

   <button
   kendoButton [imageUrl]=“‘https://demos.telerik.com/kendo-ui/content/shared/icons/sports/snowboarding.png'&#8221;>Snowboarding</button>
   

   Your buttons must be like this:

   

• Primary Button
  

  The Button enables you to highlight the actions to the user by enhancing its appearance.

  For making any type of button as Primary, set the primary property to true. Like:

<button
kendoButton [primary]=“true”>Open</button>

And your output will be like:

• Toggleable Button
  

  Toggleable Button enables you to indicate whether it is active or inactive. To get this behavior, use the togglable property and set it to true.

<button
kendoButton [look]=“‘bare'” [togglable]=“true”>Submit</button>

See the output when it’s in Inactive mode:

Active:

Manage Events of Kendo UI Buttons:

If you need to manage your events in Kendo Button, just write your event name in small brackets (), with event name, like if you need to use Click event then write like this:
(click)=“functionName ()”

Use the bellow code for button:

<button
kendoButton [primary]=“true” (click)=“testClick()”
>Click Me</button>

“testClick” its function Name replace this with your function, need to be call. Now create a function in “aap.component.ts”, like:

public testClick(): void {

alert(“Kendo Button Click Event is Working !!”);

}

Now run your app in browser, check the page:

Now click to test your click event.

Now you can use any Events Click, focus or more.
