Web Components Tree Grid Summaries
La función Resúmenes de Ignite UI for Web Components en Web Components cuadrícula de árbol funciona a nivel de columna como pie de página de grupo. Web Components resúmenes de IgcTreeGrid es una característica poderosa que permite al usuario ver la información de la columna en un contenedor separado con un conjunto predefinido de elementos de resumen predeterminados, según el tipo de datos dentro de la columna o mediante la implementación de una plantilla personalizada en el IgcTreeGridComponent
.

El resumen de la columna es una función de todos los valores de la columna; a menos que se aplique un filtrado, el resumen de la columna será función de los valores de los resultados filtrados.
IgcTreeGridComponent
Los resúmenes también se pueden habilitar a nivel de columna en Ignite UI for Web Components, lo que significa que solo puede activarlo para las columnas que necesite. IgcTreeGridComponent
Resúmenes le proporciona un conjunto predefinido de resúmenes predeterminados, en función del tipo de datos de la columna, para que pueda ahorrar algo de tiempo:
Para string
y boolean
dataType
, está disponible la siguiente función:
- Contar
Para los tipos de datos number
, currency
y percent
, están disponibles las siguientes funciones:
- Contar
- mín.
- máx.
- Promedio
- Suma
Para el tipo de datos date
, están disponibles las siguientes funciones:
- Contar
- Más temprano
- El último
Todos los tipos de datos de columna disponibles se pueden encontrar en el tema oficial Tipos de columna.
IgcTreeGridComponent
Los resúmenes se habilitan por columna configurando hasSummary
propiedad a verdadero. También es importante tener en cuenta que los resúmenes de cada columna se resuelven según el tipo de datos de columna. En IgcTreeGridComponent
El tipo de datos de columna predeterminado es string
, así que si quieres number
o date
resúmenes específicos, debe especificar el dataType
propiedad como number
o date
. Tenga en cuenta que los valores de resumen se mostrarán localizados, de acuerdo con la cuadrícula locale
y columna pipeArgs
.
<igc-tree-grid id="grid1" auto-generate="false" height="800px" width="800px">
<igc-column field="ID" header="Order ID">
</igc-column>
<igc-column field="Name" header="Order Product" has-summary="true">
</igc-column>
<igc-column field="Units" header="Units" editable="true" data-type="number" has-summary="true">
</igc-column>
</igc-tree-grid>
html
La otra forma de habilitar/deshabilitar resúmenes para una columna específica o una lista de columnas es usar el método enableSummaries
public / disableSummaries
de la IgcTreeGridComponent
.
<igc-tree-grid auto-generate="false" name="treeGrid" id="treeGrid" primary-key="ID">
<igx-column field="ID" header="Order ID" width="200px">
</igx-column>
<igx-column field="Name" header="Order Product" width="200px" [hasSummary]="true">
</igx-column>
<igx-column field="Units" width="200px" [editable]="true" [dataType]="'number'" [hasSummary]="true">
</igx-column>
</igc-tree-grid>
<button id="enableBtn">Enable Summary</button>
<button id="disableBtn">Disable Summary </button>
html
constructor() {
var treeGrid = this.treeGrid = document.getElementById('treeGrid') as IgcTreeGrid;
var enableBtn = this.enableBtn = document.getElementById('enableBtn') as HTMLButtonElement;
var disableBtn = this.disableBtn = document.getElementById('disableBtn') as HTMLButtonElement;
treeGrid.data = this.data;
enableBtn.addEventListener("click", this.enableSummary);
disableBtn.addEventListener("click", this.disableSummary);
}
ts
public enableSummary() {
this.treeGrid.enableSummaries([
{fieldName: 'Name'},
{fieldName: 'Units'}
]);
}
public disableSummary() {
this.treeGrid.disableSummaries(['Units']);
}
typescript
Resúmenes de cuadrícula de árbol personalizados
Si estas funciones no cumplen con sus requisitos, puede proporcionar un resumen personalizado para las columnas específicas.
Para lograr esto, debe anular una de las clases base IgcSummaryOperand
, IgcNumberSummaryOperand
o IgcDateSummaryOperand
según el tipo de datos de la columna y sus necesidades. De esta manera puede redefinir la función existente o puede agregar nuevas funciones. La clase IgcSummaryOperand
proporciona la implementación predeterminada solo para el método count
. IgcNumberSummaryOperand
extiende IgcSummaryOperand
y proporciona implementación para Min
, Max
, Sum
y Average
. IgcDateSummaryOperand
amplía IgcSummaryOperand
y, además, le ofrece las versiones Earliest
y Latest
.
import { IgcSummaryResult, IgcSummaryOperand, IgcNumberSummaryOperand, IgcDateSummaryOperand } from 'igniteui-webcomponents-grids';
class MySummary extends IgcNumberSummaryOperand {
constructor() {
super();
}
operate(data?: any[]): IgcSummaryResult[] {
const result = super.operate(data);
result.push({
key: 'test',
label: 'Test',
summaryResult: data.filter(rec => rec > 10 && rec < 30).length
});
return result;
}
}
typescript
Como se ve en los ejemplos, las clases base exponen el método operate
, por lo que puede elegir obtener todos los resúmenes predeterminados y modificar el resultado, o calcular resultados resumidos completamente nuevos.
El método devuelve una lista de IgcSummaryResult
.
interface IgcSummaryResult {
key: string;
label: string;
summaryResult: any;
}
typescript
y tomar parámetros opcionales para calcular los resúmenes. Consulte Resúmenes personalizados, que acceden a toda la sección de datos a continuación.
Para calcular correctamente la altura de la fila de resumen, la cuadrícula de árbol necesita que el método Operate devuelva siempre una matriz de IgcSummaryResult con la longitud adecuada, incluso cuando los datos están vacíos.
Y ahora agreguemos nuestro resumen personalizado a la columna title
. Lo lograremos estableciendo la propiedad Summaries' en la clase que creamos a continuación.
<igc-tree-grid auto-generate="false" name="treeGrid" id="treeGrid" primary-key="ID">
<igc-column field="Name" data-type="string"></igc-column>
<igc-column field="Age" data-type="number"></igc-column>
<igc-column field="Title" data-type="string" has-summary="true" id="column1"></igc-column>
</igc-tree-grid>
html
constructor() {
var treeGrid = this.treeGrid = document.getElementById('treeGrid') as IgcTreeGrid;
var column1 = this.column1 = document.getElementById('column1') as IgcColumnComponent;
treeGrid.data = this.data;
column1.summaries = this.mySummary;
}
ts
export class TreeGridComponent implements OnInit {
mySummary = MySummary;
}
typescript
Resúmenes personalizados, que acceden a todos los datos
Ahora puede acceder a todos los datos de la cuadrícula de árbol dentro del resumen de columna personalizado. Se introducen dos parámetros opcionales adicionales en el método SummaryOperand Operate
. Como puede ver en el fragmento de código a continuación, el método operate tiene los siguientes tres parámetros:
- columnData: le proporciona una matriz que contiene los valores solo para la columna actual
- allGridData: le brinda toda la fuente de datos de la cuadrícula
- fieldName - campo de columna actual
class MySummary extends IgcNumberSummaryOperand {
constructor() {
super();
}
operate(columnData: any[], allGridData = [], fieldName?): IgcSummaryResult[] {
const result = super.operate(allData.map(r => r[fieldName]));
result.push({ key: 'totalOnPTO', label: 'Employees On PTO', summaryResult: this.count(allData.filter((rec) => rec['OnPTO']).map(r => r[fieldName])) });
return result;
}
}

Summary

ts
Cuando se define un resumen predeterminado, la altura del área de resumen se calcula por diseño en función de la columna con el mayor número de resúmenes y la--ig-size
de la cuadrícula. Utilice la summaryRowHeight
propiedad input para invalidar el valor predeterminado. Como argumento, espera un valor numérico, y establecer un valor falso desencadenará el comportamiento de tamaño predeterminado del pie de página de la cuadrícula.

Resúmenes deshabilitados
La disabled-summaries
propiedad proporciona un control preciso por columna sobre la característica de resumen de cuadrícula de árbol de Web Components. Esta propiedad permite a los usuarios personalizar los resúmenes que se muestran para cada columna de IgcTreeGrid, lo que garantiza que solo se muestren los datos más relevantes y significativos. Por ejemplo, puede excluir tipos de resumen específicos, por ejemplo ['count', 'min', 'max']
, especificando sus claves de resumen en una matriz.
Esta propiedad también se puede modificar dinámicamente en tiempo de ejecución a través del código, lo que proporciona flexibilidad para adaptar los resúmenes de IgcTreeGrid a los cambios en los estados de la aplicación o a las acciones del usuario.
En los ejemplos siguientes se muestra cómo utilizar la disabled-summaries
propiedad para administrar resúmenes de diferentes columnas y excluir tipos de resumen predeterminados y personalizados específicos en la cuadrícula de árbol de Web Components:
<!-- Disable default summaries -->
<igc-column
field="UnitPrice"
header="Unit Price"
data-type="number"
has-summary="true"
disabled-summaries="['count', 'sum', 'average']"
>
</igc-column>
<!-- Disable custom summaries -->
<igc-column
field="UnitsInStock"
header="Units In Stock"
data-type="number"
has-summary="true"
summaries="discontinuedSummary"
disabled-summaries="['discontinued', 'totalDiscontinued']"
>
</igc-column>
html
Para UnitPrice
, los resúmenes predeterminados como count
, sum
, y average
están deshabilitados, dejando otros como y min
max
activos.
En el caso UnitsInStock
de los resúmenes personalizados, como discontinued
y totalDiscontinued
se excluyen mediante la disabled-summaries
propiedad.
En tiempo de ejecución, los resúmenes también se pueden deshabilitar dinámicamente mediante la disabled-summaries
propiedad. Por ejemplo, puede establecer o actualizar la propiedad en columnas específicas mediante programación para adaptar los resúmenes mostrados en función de las acciones del usuario o los cambios de estado de la aplicación.

Resúmenes de formato
De forma predeterminada, los resultados de resumen, producidos por los operandos de resumen integrados, se localizan y formatean de acuerdo con la locale
de la cuadrícula y la columna pipeArgs
. Cuando se utilizan operandos personalizados, la locale
y pipeArgs
no se aplican. Si desea cambiar la apariencia predeterminada de los resultados del resumen, puede formatearlos usando la propiedad summaryFormatter
.

Resúmenes infantiles
Admite IgcTreeGridComponent
resúmenes independientes para los nodos raíz y para cada nivel de nodo secundario anidado. Los resúmenes que se muestran se pueden configurar mediante la summaryCalculationMode
propiedad. Los resúmenes de nivel secundario se pueden mostrar antes o después de los nodos secundarios que utilizan la summaryPosition
propiedad. Junto con estas dos propiedades, la propiedad exposes y showSummaryOnCollapse
que le permite determinar si la IgcTreeGridComponent
fila de resumen permanece visible cuando se contrae el nodo primario al que se hace referencia.
Los valores disponibles de la propiedad summaryCalculationMode
son:
RootLevelOnly
- Los resúmenes se calculan solo para los nodos de nivel raíz.ChildLevelsOnly
: los resúmenes se calculan solo para los niveles secundarios.RootAndChildLevels
: los resúmenes se calculan tanto para el nivel raíz como para el nivel secundario. Este es el valor predeterminado.
Los valores disponibles de la propiedad summaryPosition
son:
Top
- La fila de resumen aparece antes de la lista de filas secundarias.Bottom
- La fila de resumen aparece después de la lista de filas secundarias. Este es el valor predeterminado.
La propiedad showSummaryOnCollapse
es booleana. Su valor predeterminado está establecido en false, lo que significa que la fila de resumen se ocultará cuando se contraiga la fila principal. Si la propiedad se establece en verdadero, la fila de resumen permanece visible cuando se contrae la fila principal.
La propiedad summaryPosition solo se aplica a los resúmenes de nivel secundario. Los resúmenes de nivel raíz aparecen siempre fijos en la parte inferior de IgcTreeGridComponent.

Navegación por teclado
Se puede navegar por las filas de resumen con las siguientes interacciones de teclado:
- ARRIBA: navega una celda hacia arriba.
- ABAJO: navega una celda hacia abajo.
- IZQUIERDA: navega una celda hacia la izquierda.
- DERECHA: navega una celda hacia la derecha.
- CTRL + IZQUIERDA o INICIO: navega a la celda más a la izquierda.
- CTRL + DERECHA o FINAL: navega a la celda más a la derecha.
Estilo
Además de los temas predefinidos, la cuadrícula se puede personalizar aún más configurando algunas de las propiedades CSS disponibles. En caso de que desee cambiar algunos de los colores, primero debe establecer una clase para la cuadrícula:
<igc-tree-grid class="grid"></igc-tree-grid>
html
Luego configure las propiedades CSS relacionadas para esa clase:
.grid {
--ig-grid-summary-background-color:#e0f3ff;
--ig-grid-summary-focus-background-color: rgba( #94d1f7, .3 );
--ig-grid-summary-label-color: rgb(228, 27, 117);
--ig-grid-summary-result-color: black;
