Ignite UI wrappers for Angular

NOTE: Ignite UI wrappers for Angular are deprecated! Use igniteui-angular native Angular components instead!

Use the components found in projects\igniteui-angular-wrappers\src\public-api.ts to use Ignite UI controls in Angular applications. Work with the running samples here.

IMPORTANT The repository has been renamed from igniteui-angular2 to igniteui-angular-wrappers. Read more on our new naming convention.

Requirements

• jQuery v1.9.1 and later
• jQuery UI v1.9.0 and later
• Angular v2.0 beta and later
• Ignite UI 15.2 and later

Running the samples

To run the samples, you need Node.js installed on your machine. Afterwards, from your terminal run the following commands:

1. git clone https://github.com/IgniteUI/igniteui-angular-wrappers
2. cd igniteui-angular-wrappers
3. npm install
4. npm start

igniteui-angular-wrappers depends on the ignite-ui-full licensed package. Follow this guide on setting up access to the Ignite UI private npm feed and add the dependency to the package.json.

"dependencies": {
	"@infragistics/ignite-ui-full": "latest"
}

Getting Started

Ignite UI CLI

To get started with the Ignite UI CLI and the Ignite UI Angular wrappers:

npm i -g igniteui-cli
ig new  --framework=angular --type=ig-ts
cd 
ig add combo 
ig start

Initializing controls

In an Angular application, Ignite UI controls support markup initialization which is done by using custom tags.

Custom tags

Each control implements a custom tag component where the tag name is formed by splitting each capital letter in the control name with the - symbol.

Note: It is recommended to use closing tags () over the self-closing tags (), because the latter are known to make issues on some browsers (depending on the used document mode).

Examples:

Configuring Control Options

There are two mandatory attributes that need to be set to an Ignite UI control custom tag: options - points to a property on the application component class containing the control's configuration. widgetId - the control requires an id to be assigned to it.

Example:

@Component({
    selector: 'my-app',
    template: ``
})
export class AppComponent {
    private gridOptions: IgGrid;
    private id: string;
    private data: any;

    constructor() {
        this.data = Northwind.getData();
        this.id ='grid1';
        this.gridOptions = {
            width: "100%",
            height: "400px",
            autoGenerateColumns: true
        };
    }
}

In this example options attribute points to gridOptions property on the application compoment class and widgetId points to the id property.

Configuring Top Level Control Options

All top level options are allowed to be set as attributes of an Ignite UI control custom tag. In this case options attribute is not mandatory, but it is allowed. And if both - options and top-level attributes are combined, top-level attributes will override options, when there are overlapping properties. Also changing top-level attribute will apply the change to the widget, only if the option is settable.

Example:

@Component({
    selector: 'my-app',
    template: `
    `
})
export class AppComponent {
    private id: string;
    private data: any;
    private w: string;
    private h: string;
    private pKey: string;

    constructor() {
        this.data = Northwind.getData();
        this.id ='grid1';
        this.w = '100%';
        this.h = '400px';
        this.pKey = 'ProductID';
    }
}

Other custom tags

There are two custom tags and that are used in igGrid/igTreeGrid/igHierarchicalGrid to configure the columns and features options accordingly.

Example:

Each of the grids features is also represented by a custom tag.

Examples:

Apply new set of Control Options

In order to change the more options at once (or recreate the component with another set of options), the new configuration can be applied to the options property.

Example:

@Component({
    selector: 'my-app',
    template: ``
})
export class AppComponent {
    private gridOptions: IgGrid;
    private id: string;
    private data: any;

    constructor() {
        this.data = Northwind.getData();
        this.id ='grid1';
        this.gridOptions = {
            width: "100%",
            height: "400px",
            autoGenerateColumns: true
        };
    }

    recreateGrid() {
        this.gridOptions = {
            dataSource: Northwind.getAnotherData(),
            width: "700px",
            autoGenerateColumns: true,
            features: [
                { name: "Paging" }
            ]
        };
    }
}

In this example options attribute points to gridOptions and changing in reference will destroy the grid, combine the old options with new ones and create the grid with the combined options. Also note that the new grid will have height of 400px, even though it's not defined into the new options, because of the combination with new options. If disabling an option is required set it to null, undefined, [] or {}.

Handling events

Binding to control events is achieved by assigning attributes where the name of the attribute is the name of the control's event name surrounded by parenthesis and the value is the name of the event handler.

Examples:

@Component({
    selector: 'my-app',
    template: ``
})
export class AppComponent {
    private gridOptions: IgGrid;
    private id: string;
    private data: any;
    private dataBindHandler: any;
    
    constructor() {
        this.data = Northwind.getData();
        this.id ='grid1';
        this.gridOptions = {
            width: "100%",
            height: "400px",
            autoGenerateColumns: true
        };
    }
    
    dataBindHandler(event, ui) {
        // event handler code    
    }
}

Binding to igGrid* feature events is done in the control's configuration code.

Example:

@Component({
    selector: 'my-app',
    template: ``
})
export class AppComponent {
    private gridOptions: IgGrid;
    private id: string;
    private data: any;

    constructor() {
        this.data = Northwind.getData();
        this.id ='grid1';
        this.gridOptions = {
            width: "100%",
            height: "400px",
            autoGenerateColumns: true,
            features: [
                {
                    name: "Filtering",
                    dataFiltered: function (evt, ui) {
                        // event handler code
                    }
                    
                }
            ]
        };
    }
}

In this example igGridFiltering dataFiltered event is handled in the application component class.

Calling Component methods

Component methods can be called by accessing the component from the view. For example:

@Component({
    selector: 'my-app',
    template: '
        
            
        
    '
})
export class AppComponent {
    private gridOptions: IgGrid;
    @ViewChild("grid1") myGrid: IgGridComponent;
    private id: string;
    constructor() { ... }
     
    ngAfterViewInit() {
        //call grid method
        var cell = this.myGrid.cellById(1, "Name");
        //call grid paging method
        this.myGrid.featuresList.paging.pageIndex(2);
    }
}

Two-way Data Binding

The following controls currently support two-way data binding:

1. igGrid
2. igTreeGrid
3. igHierarchicalGrid
4. igCombo
5. igEditors
6. igTree

For the two-way data binding to work you need to assign the data source as a property in the template. Example:

Note: Two-way data binding won't work if you use options.dataSource in the .ts file as a configuration.

To manually trigger change detection use the markForCheck API.

Use igDataSource inside Angular app

Thanks to the @types/ignite-ui, it is possible to create an instance of the all of the Ignite UI data sources.

let source = new Infragistics.DataSource(settings);

This data source instance is granted with intellisense about igDataSource methods.

source.dataBind();

Review the following demo for more information.

Running tests

The command for running the tests is:

npm test

After that, if all tests successfully passed a code coverage for the public-api.ts file will be generated under the ./coverage/igniteui-angular-wrappers folder.

To see the code coverage you can open one of the html files under ./coverage/igniteui-angular-wrappers/src.
