        <data-column key="createdBy.name" title="Created By"></data-column>
    </data-columns>
</alfresco-datatable>
import { ObjectDataTableAdapter } from 'ng2-alfresco-datatable';

@Component({...})
export class DataTableDemo {
    data: ObjectDataTableAdapter;

    constructor() {
        this.data = new ObjectDataTableAdapter(
            // data
            [
                {
                    id: 1,

        <alfresco-datatable></alfresco-datatable>
    </child-component>
</root-component>
onRowClick(event) {
    console.log(event);
}

Empty content template

You can add a template that will be showed when there are no result in your datatable:

<alfresco-datatable
    [data]="data"
    [actions]="contentActions"
    [multiselect]="multiselect"
    (showRowContextMenu)="onShowRowContextMenu($event)"
    (showRowActionsMenu)="onShowRowActionsMenu($event)"
    (executeRowAction)="onExecuteRowAction($event)"
    (rowClick)="onRowClick($event)"
    (rowDblClick)="onRowDblClick($event)">
    
    
        <no-content-template>
            <!--Add your custom empty template here-->
            <ng-template>
                <h1>Sorry, no content</h1>
            </ng-template>
        </no-content-template>
        
</alfresco-datatable>

Loading content template

You can add a template that will be showed during the loading of your data:

<alfresco-datatable
    [data]="data"
    [actions]="contentActions"
    [multiselect]="multiselect"
    [loading]=isLoading()"
    (showRowContextMenu)="onShowRowContextMenu($event)"
    (showRowActionsMenu)="onShowRowActionsMenu($event)"
    (executeRowAction)="onExecuteRowAction($event)"
    (rowClick)="onRowClick($event)"
    (rowDblClick)="onRowDblClick($event)">
    
        <loading-content-template>
            <ng-template>
               <!--Add your custom loading template here-->
                <md-progress-spinner
                    class="adf-document-list-loading-margin"
                    [color]="'primary'"
                    [mode]="'indeterminate'">
                </md-progress-spinner>
            </ng-template>
        </loading-content-template>
        
</alfresco-datatable>
    isLoading(): boolean {
        //your custom logic to identify if you are in a loading state 
    }

Note: the <loading-content-template> and <no-content-template> can be used together

Column Templates

It is possible assigning a custom column template like the following:

<alfresco-datatable ...>
    <data-columns>
        <data-column title="Version" key="properties.cm:versionLabel">
            <template let-value="value">
                <span>V. {{value}}</span>
            </template>
        </data-column>
    </data-columns>
</alfresco-datatable>

Example above shows access to the underlying cell value by binding value property to the underlying context value:

<template let-value="value">

Alternatively you can get access to the entire data context using the following syntax:

<template let-entry="$implicit">

That means you are going to create local variable entry that is bound to the data context via Angular's special $implicit keyword.

<template let-entry="$implicit">
    <span>V. {{entry.data.getValue(entry.row, entry.col)}}</span>
</template>

In the second case entry variable is holding a reference to the following data context:

{
    data: DataTableAdapter,
    row: DataRow,
    col: DataColumn
}

Events

rowClick event

This event is emitted when user clicks the row.

Event properties:

sender: any     // DataTable instance 
value: DataRow, // row clicked
event: Event    // original HTML DOM event

Handler example:

onRowClicked(event: DataRowEvent) {
    console.log(event.value);
}

This event is cancellable, you can use event.preventDefault() to prevent default behaviour.

rowDblClick event

This event is emitted when user double-clicks the row.

Event properties:

sender: any     // DataTable instance 
value: DataRow, // row clicked
event: Event    // original HTML DOM event

Handler example:

onRowDblClicked(event: DataRowEvent) {
    console.log(event.value);
}

This event is cancellable, you can use event.preventDefault() to prevent default behaviour.

showRowContextMenu event

Emitted before context menu is displayed for a row.

Note that DataTable itself does not populate context menu items, you can provide all necessary content via handler.

Event properties:

value: {
    row: DataRow,
    col: DataColumn,
    actions: []
}

Handler example:

onShowRowContextMenu(event: DataCellEvent) {
    event.value.actions = [
        { ... },
        { ... }
    ]
}

This event is cancellable, you can use event.preventDefault() to prevent default behaviour.

DataTable will automatically render provided menu items.

Please refer to ContextMenu documentation for more details on context actions format and behavior.

showRowActionsMenu event

Emitted before actions menu is displayed for a row. Requires actions property to be set to true.

Event properties:

value: {
    row: DataRow,
    action: any
}

Note that DataTable itself does not populate action menu items, you can provide all necessary content via handler.

This event is cancellable, you can use event.preventDefault() to prevent default behaviour.

executeRowAction event

Emitted when row action is executed by user.

Usually accompanies showRowActionsMenu event. DataTable itself does not execute actions but provides support for external integration. If there were actions provided with showRowActionsMenu event then executeRowAction will be automatically executed when user clicks corresponding menu item.

<alfresco-datatable
    [data]="data"
    [multiselect]="multiselect"
    [actions]="true"
    (showRowActionsMenu)="onShowRowActionsMenu($event)"
    (executeRowAction)="onExecuteRowAction($event)">
</alfresco-datatable>
import { DataCellEvent, DataRowActionEvent } from 'ng2-alfresco-datatable';

onShowRowActionsMenu(event: DataCellEvent) {
    let myAction = {
        title: 'Hello'
        // your custom metadata needed for onExecuteRowAction
    };
    event.value.actions = [
        myAction
    ];
}

onExecuteRowAction(event: DataRowActionEvent) {
    let args = event.value;
    console.log(args.row);
    console.log(args.action);
    window.alert(`My custom action: ${args.action.title}`);
}

Developers are allowed putting any payloads as row actions. The only requirement for the objects is having title property.

Once corresponding action is clicked in the dropdown menu DataTable invokes executeRowAction event where you can handle the process, inspect the action payload and all custom properties defined earlier, and do corresponding actions.

Data sources

DataTable component gets data by means of data adapter. It is possible having data retrieved from different kinds of sources by implementing a custom DataTableAdapter using the following interfaces:

interface DataTableAdapter {
    selectedRow: DataRow;
    getRows(): Array<DataRow>;
    setRows(rows: Array<DataRow>): void;
    getColumns(): Array<DataColumn>;
    setColumns(columns: Array<DataColumn>): void;
    getValue(row: DataRow, col: DataColumn): any;
    getSorting(): DataSorting;
    setSorting(sorting: DataSorting): void;
    sort(key?: string, direction?: string): void;
}

interface DataRow {
    isSelected: boolean;
    hasValue(key: string): boolean;
    getValue(key: string): any;
}

interface DataColumn {
    key: string;
    type: string; // text|image|date
    format?: string;
    sortable?: boolean;
    title?: string;
    srTitle?: string;
    cssClass?: string;
    template?: TemplateRef<any>;
}

DataTable provides ObjectDataTableAdapter out-of-box. This is a simple data adapter implementation that binds to object arrays and turns object fields into columns:

let data = new ObjectDataTableAdapter(
    // data
    [
        { id: 1, name: 'Name 1' },
        { id: 2, name: 'Name 2' }
    ],
    // schema
    [
        { 
            type: 'text', 
            key: 'id', 
            title: 'Id', 
            sortable: true 
        },
        {
            type: 'text', 
            key: 'name', 
            title: 'Name', 
            sortable: true
        }
    ]
);

Generate schema

Is possible to auto generate your schema if you have only the data row

let data =  [
    { id: 2, name: 'abs' },
    { id: 1, name: 'xyz' }
];

let schema = ObjectDataTableAdapter.generateSchema(data);

/*Auto generated schema value:
[
    { 
        type: 'text', 
        key: 'id', 
        title: 'Id', 
        sortable: false 
    },
    {
        type: 'text', 
        key: 'name', 
        title: 'Name', 
        sortable: false
    }
] 
*/

Pagination Component

The pagination object is a generic component to paginate component. The Alfresco API are paginated and returns a Pagination object. You can use the pagination object to feed the pagination component and then listen to the event which return the current pagination and query again the API with the options choose by the user.

DataTable demo

Properties

Name Type Default Description
supportedPageSizes numer[] [5, 10, 20, 50, 100] This array describe the set of options showed in the pick list
maxItems boolean false Max number of element showed per page. If you pick another size from the pick list this option will be overwritten
pagination Pagination {count: 0, totalItems: 0, skipCount: 0, maxItems: 20 , hasMoreItems: true} The Alfresco Api return a pagination object, you can use it to feed the pagination component, or create your own.

Events

Name Description
changePageSize Emitted when user picks one of the options from the pick list
nextPage Emitted when user clicks next page button
prevPage Emitted when user clicks prev page button

All the events carry with them the current pagination object.
