Web Components Fijación de columnas de cuadrícula de árbol

La función de fijación de columnas Ignite UI for Web Components en Web Components cuadrícula de árbol permite a los desarrolladores bloquear columnas específicas en el orden deseado, lo que garantiza la visibilidad todo el tiempo, incluso cuando los usuarios se desplazan horizontalmente por el IgcGridComponent. Hay una interfaz de usuario integrada para la fijación de columnas, a la que se puede acceder a través de la barra de herramientas de la cuadrícula de árbol Web Components. Además, los desarrolladores tienen la flexibilidad de crear una interfaz de usuario personalizada que cambia el estado de los pines de las columnas.

API de fijación de columnas

El anclaje de columnas se controla a través de la pinned propiedad de the IgcColumnComponent. Las columnas ancladas se representan en el lado izquierdo de la IgcTreeGridComponent forma predeterminada y permanecen fijas a través del desplazamiento horizontal de las columnas no ancladas en el IgcTreeGridComponent cuerpo.

<igc-tree-grid id="treeGrid" primary-key="ID" foreign-key="ParentID" auto-generate="false">
    <igc-column field="Name" pinned="true"></igc-column>
    <igc-column field="Title"></igc-column>
    <igc-column field="ID"></igc-column>
</igc-tree-grid>
html

También puede utilizar los métodos pinColumn o unpinColumn de IgcTreeGridComponent para fijar o desanclar columnas por su IgcTreeGridComponent de campo:

this.treeGrid.pinColumn('Title');
this.treeGrid.unpinColumn('Name');
typescript

Ambos métodos devuelven un valor booleano que indica si su operación respectiva fue exitosa o no. Generalmente la razón por la que fallan es que la columna ya se encuentra en el estado deseado.

Una columna está fijada a la derecha de la columna fijada más a la derecha. Se puede cambiar el orden de las columnas fijadas suscribiéndose al evento ColumnPin y cambiando la propiedad InsertAtIndex de los argumentos del evento al índice de posición deseado.

<igc-tree-grid id="dataGrid" auto-generate="true"></igc-tree-grid>
html

constructor() {
    var dataGrid = document.getElementById('dataGrid') as IgcTreeGridComponent;
    dataGrid.data = this.data;
    dataGrid.addEventListener("columnPin", this.columnPinning);
}
typescript

public columnPinning(event) {
    if (event.detail.column.field === 'Name') {
        event.detail.insertAtIndex = 0;
    }
}
typescript

Posición de fijación

Puede cambiar la posición de fijación de la columna mediante la opción de configuración pinning. Le permite establecer la posición de las columnas en Inicio o Fin. Cuando se establece en Fin, las columnas se representan al final de la cuadrícula, después de las columnas sin fijar. Las columnas no fijadas se pueden desplazar horizontalmente, mientras que las columnas fijadas permanecen fijas a la derecha.

<igc-tree-grid id="dataGrid" auto-generate="true"></igc-tree-grid>
html

IU de fijación de columnas personalizada

Puede definir su interfaz de usuario personalizada y cambiar el estado del pin de las columnas a través de la API relacionada.

Digamos que en lugar de una barra de herramientas le gustaría definir íconos de pin en los encabezados de las columnas en los que el usuario final puede hacer clic para cambiar el estado del pin de la columna en particular.

Esto se puede hacer creando una plantilla de encabezado para las columnas con un ícono personalizado.

<igc-tree-grid id="treeGrid" primary-key="ID" foreign-key="ParentID" auto-generate="false" width="100%" height="620px">
    <igc-column id="Name" field="Name" data-type="String" width="250px"></igc-column>
    <igc-column id="Title" field="Title" data-type="String" width="300px"></igc-column>
    <igc-column id="ID" field="ID" data-type="Number" width="200px"></igc-column>
    <igc-column id="HireDate" field="HireDate" header="Hire Date" data-type="Date" width="200px"></igc-column>
    <igc-column id="Age" field="Age" data-type="Number" width="200px"></igc-column>
    <igc-column id="Address" field="Address" data-type="String" width="200px"></igc-column>
    <igc-column id="City" field="City" data-type="String" width="200px"></igc-column>
    <igc-column id="Country" field="Country" data-type="String" width="200px"></igc-column>
    <igc-column id="Fax" field="Fax" data-type="string" width="200px"></igc-column>
    <igc-column id="PostalCode" field="PostalCode" header="Postal Code" data-type="String" width="200px"></igc-column>
    <igc-column id="Phone" field="Phone" data-type="String" width="200px"></igc-column>

    Address.headerTemplate = this.pinHeaderTemplate;
    City.headerTemplate = this.pinHeaderTemplate;
    Country.headerTemplate = this.pinHeaderTemplate;
    Fax.headerTemplate = this.pinHeaderTemplate;
    PostalCode.headerTemplate = this.pinHeaderTemplate;
    Phone.headerTemplate = this.pinHeaderTemplate;
}

public pinHeaderTemplate = (ctx: IgcCellTemplateContext) => {
    return html`
        <div class="title-inner">
            <span style="float:left">${ctx.cell.column.header}</span>
            <igc-icon class="pin-icon" fontSet="fas" name="fa-thumbtack" @click="${() => toggleColumn(ctx.cell.column)}"></igx-icon>
        </div>
    `;
}
ts

Al hacer clic en el icono personalizado, el estado del pin de la columna relacionada se puede cambiar utilizando los métodos API de la columna.

public toggleColumn(col: IgcColumnComponent) {
    col.pinned ? col.unpin() : col.pin();
}

Limitaciones de fijación

• Establecer el ancho de las columnas en porcentaje (%) explícitamente hace que el cuerpo IgcTreeGridComponent y el contenido del encabezado estén desalineados cuando hay columnas fijadas. Para que la fijación de columnas funcione correctamente, los anchos de las columnas deben estar en píxeles (px) o ser asignados automáticamente por IgcTreeGridComponent.

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 ID para la cuadrícula:

<igc-tree-grid id="grid"></igc-tree-grid>
html

Luego establezca las propiedades CSS relacionadas con esta clase:

#grid {
    --ig-grid-pinned-border-width: 5px;
    --ig-grid-pinned-border-color: #FFCD0F;
    --ig-grid-pinned-border-style: double;
    --ig-grid-cell-active-border-color: #FFCD0F;
}
