This component is used to present a data set in a grid of columns and rows.
You can set:
title
)loadMoreItemsLabel
, loadingItemsLabel
- when loading is in progress)Example
<c8y-data-grid
[title]="'My objects'"
[loadMoreItemsLabel]="'Load more objects'"
[loadingItemsLabel]="'Loading objects…'"
></c8y-data-grid>
The component allows to control some visual settings via displayOptions
:
displayOptions: DisplayOptions = {
bordered: true,
striped: true,
filter: true,
gridHeader: true
};
Further visual settings can be set in individual columns with:
Header and cell rendering can be also customized with own components (see "Columns" section below for an example).
You can define what should be displayed when there are no items to be displayed in the grid by passing an element with c8y-empty-state
class, e.g.:
<c8y-data-grid (...)>
<c8y-ui-empty-state
[icon]="'search'"
[title]="'No results to display.' | translate"
[subtitle]="'Refine your search terms or check your spelling.' | translate"
[horizontal]="true"
></c8y-ui-empty-state>
</c8y-data-grid>
You can define columns by passing a list of objects compliant with Column
interface. The most basic definition contains:
name
- the name of the columnheader
- the header text for the columnpath
- the path in item's object from where the value should be takenThere are default renderers for header, cell and filtering form, but they can be overridden by custom components for fine-grained control over how these elements are presented.
Let's cosnider the following template:
<c8y-data-grid [columns]="columns"></c8y-data-grid>
and the following columns list:
columns: Column[] = [
{
name: 'id',
header: 'ID',
path: 'id',
filterable: true,
sortable: true
},
{
name: 'name',
header: 'Name',
path: 'name',
filterable: true,
sortable: true
},
new TypeDataGridColumn()
];
The first two columns will use default renderers but the third one will be customized. TypeDataGridColumn
needs to implement Column
interface and set the renderers:
import { Type } from '@angular/core';
import { Column, ColumnDataType, SortOrder, FilterPredicateFunction } from '@c8y/ngx-components';
import { TypeHeaderCellRendererComponent } from './type.header-cell-renderer.component';
import { TypeCellRendererComponent } from './type.cell-renderer.component';
import { TypeFilteringFormRendererComponent } from './type.filtering-form-renderer.component';
/**
* Defines a class for custom Type column.
* Implements `Column` interface and sets basic properties, as well as custom components.
*/
export class TypeDataGridColumn implements Column {
name: string;
path?: string;
header?: string;
dataType?: ColumnDataType;
visible?: boolean;
positionFixed?: boolean;
gridTrackSize?: string;
headerCSSClassName?: string | string[];
headerCellRendererComponent?: Type<any>;
cellCSSClassName?: string | string[];
cellRendererComponent?: Type<any>;
sortable?: boolean;
sortOrder?: SortOrder;
filterable?: boolean;
filteringFormRendererComponent?: Type<any>;
filterPredicate?: string | FilterPredicateFunction;
externalFilterQuery?: string | object;
constructor() {
this.name = 'type';
this.header = 'Type';
this.headerCellRendererComponent = TypeHeaderCellRendererComponent;
this.cellRendererComponent = TypeCellRendererComponent;
this.filterable = true;
this.filteringFormRendererComponent = TypeFilteringFormRendererComponent;
this.sortable = false;
}
}
Then each of the renderer components is responsible for rendering a particular part of the grid.
TypeHeaderCellRendererComponent
renders the header cell of the column:
import { Component } from '@angular/core';
import { CellRendererContext } from '@c8y/ngx-components';
/**
* The example component for custom header renderer.
* The header text is taken from `this.context.property` which contains current column object.
* Additionally the header has custom icon element and styled span element.
*/
@Component({
template: `
<i c8yIcon="rocket"></i>
<span style="text-transform: uppercase; font-variant: small-caps; text-decoration: underline;">
{{ context.property.header }}
</span>
`
})
export class TypeHeaderCellRendererComponent {
constructor(public context: CellRendererContext) {}
}
TypeCellRendererComponent
renders the data cell of the column:
import { Component, forwardRef, Inject } from '@angular/core';
import { CellRendererContext } from '@c8y/ngx-components';
import { ServerGridExampleService } from '../server-grid-example.service';
/**
* The example component for custom cell renderer.
* It gets `context` with the current row item and the column.
* Additionally, a service is injected to provide a helper method.
* The template displays the icon and the label with additional styling.
*/
@Component({
template: `
<span>
<i [c8yIcon]="value.icon" class="m-r-5"></i>
<code>{{ value.label }}</code>
</span>
`
})
export class TypeCellRendererComponent {
/** Returns the icon and label for the current item. */
get value() {
return this.service.getTypeIconAndLabel(this.context.item);
}
constructor(
public context: CellRendererContext,
@Inject(ServerGridExampleService) public service: ServerGridExampleService
) {}
}
The example above also shows how to use a custom service to process the current item before displaying it in the template.
TypeFilteringFormRendererComponent
renders the filtering form for the column where filtering options can be selected and applied or reset:
import { Component, Inject } from '@angular/core';
import { FilteringFormRendererContext } from '@c8y/ngx-components';
import { ServerGridExampleService, TypeFilteringModel } from '../server-grid-example.service';
/**
* This is the example component for custom filtering form.
* The form can contain any inputs you want.
* The important thing is to invoke one of the 2 methods:
*
* - `applyFilter` which sets `filterPredicate` or `externalFilterQuery` in the column,
* these values will later be used to generate the query
* - `resetFilter` which resets filter settings in the column
*
* Our example shows the list of checkboxes. Selecting them modifies the query being sent.
*/
@Component({
template: `
<form #filterForm="ngForm">
<strong>Show managed objects of type:</strong>

export class TypeFilteringFormRendererComponent {

constructor(
public context: FilteringFormRendererContext,
@Inject(ServerGridExampleService) public service: ServerGridExampleService
) {
// restores the settings from current column setup
this.model = (this.context.property.externalFilterQuery || {}).model || {};
}
/**
* Applies the filter.
* Sets `externalFilterQuery.model` to restore the same settings the next time the form is displayed.
* Sets `externalFilterQuery.query` to pass the query object to be included in the final data grid query.
*/
applyFilter() {
this.context.applyFilter({
externalFilterQuery: {
model: this.model,
query: this.service.getTypeQuery(this.model)
}
});
}
/** Restes the filter, just call the method from context. */
resetFilter() {
this.context.resetFilter();
}
}
Later it will be presented how to use externalFilterQuery
to build a query to fetch data from the server.
Rows can be provided to the data grid via rows
input. However, this is usually only useful for predefined set of data which is then processed on the client side. If you want to know more about this way of providing data, see the example in our tutorial application.
Another way of providing data to the data grid is to use serverSideDataCallback
input. The function provided to this input will be invoked whenever the grid needs to load data, i.e. on initial load, on next page load, on column filtering or sorting settings change. This function should take a DataSourceModifier
object and return a ServerSideDataResult
object. The modifier represents the current state of the grid, i.e. filtering/sorting settings in columns, search text from the search input, selected items and pagination. Based on this state, you can perform any logic you need to determine what data should be displayed and then return it, along with additional statistics needed for accurate handling of the paging:
size
: the number of all items that can be displayed in a grid when no filters are appliedfilteredSize
: the number of items that match current filtersLet's consider the following example:
/**
* This method loads data when data grid requests it (e.g. on initial load or on column settings change).
* It gets the object with current data grid setup and is supposed to return:
* full response, list of items, paging object, the number of items in the filtered subset, the number of all items.
*/
async onDataSourceModifier(
dataSourceModifier: DataSourceModifier
): Promise<ServerSideDataResult> {
let serverSideDataResult: ServerSideDataResult;
const { res, data, paging } = await this.service.getData(
dataSourceModifier.columns,
dataSourceModifier.pagination
);
const filteredSize: number = await this.service.getCount(
dataSourceModifier.columns,
dataSourceModifier.pagination
);
const size: number = await this.service.getTotal();
serverSideDataResult = { res, data, paging, filteredSize, size };
return serverSideDataResult;
}
As you can see, we're using the state from dataSourceModifier
to execute the queries and return the result. The actual implementation of these 3 queries might vary depending on your use case (what endpoint is used, what kind of columns you defined, etc.). In the following example we'll build and execute inventory queries based on columns with standard and custom filtering/sorting settings and pagination:
/** Returns data for current columns and pagination setup. */
async getData(columns: Column[], pagination: Pagination) {
// build filters based on columns and pagination
const filters = this.getFilters(columns, pagination);
// execute inventory query for the list of managed objects
return this.inventoryService.list(filters);
}
/** Returns the number of items matching current columns and pagination setup. */
async getCount(columns: Column[], pagination: Pagination) {
const filters = {
// build filters based on columns and pagination
...this.getFilters(columns, pagination),
// but we only need the number of items, not the items themselves
pageSize: 1,
currentPage: 1
};
return (await this.inventoryService.list(filters)).paging.totalPages;
}
/** Returns the total number of items (with no filters). */
async getTotal(): Promise<number> {
const filters = {
pageSize: 1,
withTotalPages: true
};
return (await this.inventoryService.list(filters)).paging.totalPages;
}
Two of the functions above use getFilters
method to build a query based on the columns and pagination setup:
/** Returns filters for given columns and pagination setup. */
private getFilters(columns: Column[], pagination: Pagination) {
return {
query: this.getQueryString(columns),
pageSize: pagination.pageSize,
currentPage: pagination.currentPage,
withChildren: false,
withTotalPages: true
};
}
/** Returns a query string based on columns setup. */
private getQueryString(columns: Column[]): string {
const fullQuery = this.getQueryObj(columns);
return this.queriesUtil.buildQuery(fullQuery);
}
/** Returns a query object based on columns setup. */
private getQueryObj(columns: Column[]): any {
return transform(columns, (query, column) => this.addColumnQuery(query, column), {
__filter: {},
__orderby: []
});
}
/** Extends given query with a part based on the setup of given column. */
private addColumnQuery(query: any, column: Column): void {
// when a column is marked as filterable
if (column.filterable) {
// in the case of default filtering form, `filterPredicate` will contain the string entered by a user
if (column.filterPredicate) {
// so we use it as the expected value, * allow to search for it anywhere in the property
query.__filter[column.path] = `*${column.filterPredicate}*`;
}
// in the case of custom filtering form, we're storing the query in `externalFilterQuery.query`
if (column.externalFilterQuery) {
query = this.queriesUtil.addAndFilter(query, column.externalFilterQuery.query);
}
}
// when a column is sortable and has a specified sorting order
if (column.sortable && column.sortOrder) {
// add sorting condition for the configured column `path`
query.__orderby.push({
[column.path]: column.sortOrder === 'asc' ? 1 : -1
});
}
return query;
}
You can see the above example working in our tutorial application:
The component supports actions to be invoked on individual rows or bulk actions to be invoked on multiple rows previously selected by user. You can either use predefined actions or define your own:
actionControls: ActionControl[] = [
{ type: BuiltInActionType.Edit, callback: (item) => console.dir(item) },
{ type: BuiltInActionType.Export, callback: (item) => console.dir(item) },
{ type: BuiltInActionType.Delete, callback: (item) => console.dir(item) },
{
type: 'customAction',
icon: 'online',
text: 'Custom action',
callback: (item) => console.dir(item)
}
];
bulkActionControls: BulkActionControl[] = [
{
type: BuiltInActionType.Export,
callback: (selectedItemIds) => console.dir(selectedItemIds)
},
{
type: BuiltInActionType.Delete,
callback: (selectedItemIds) => console.dir(selectedItemIds)
},
{
type: 'customAction',
icon: 'online',
text: 'Custom action',
callback: (selectedItemIds) => console.dir(selectedItemIds)
}
];
The component takes infiniteScroll
input which can have one of the following values:
auto
: attempts to load more data automatically as user scrolls down (default)show
: shows a load more button for the user to decidenone
: doesn't perform any load more actionhidden
: loads more data automatically but with no visible button for the userThe component exposes several event emitter outputs:
itemsSelect
onChildDevices
onConfigChange
onFilter
rowClick
rowMouseLeave
rowMouseOver
to which you can bind via template, e.g.:
<c8y-data-grid
(rowClick)="onRowClick($event)"
(itemsSelect)="onItemsSelect($event)"
(onConfigChange)="onConfigChange($event)"
></c8y-data-grid>
See more details about them in the outputs reference.
