在Angular 2 Kendo网格中创建下拉编辑器的步骤如下:
constructor() { }
ngOnInit() {
this.valueChange.emit(this.value);
}
onValueChange(value: any) {
this.valueChange.emit(value);
}
}
@Component({
selector: 'app-grid',
template: `
<kendo-grid [data]="gridData" [pageSize]="pageSize" [skip]="skip" [sort]="sort" [filter]="state.filter" [sortable]="true" [pageable]="true">
<kendo-grid-column field="productName" title="Product Name"></kendo-grid-column>
<kendo-grid-column field="category" title="Category"></kendo-grid-column>
<kendo-grid-column field="unitPrice" title="Unit Price"></kendo-grid-column>
<kendo-grid-column field="discontinued" title="Discontinued"></kendo-grid-column>
<kendo-grid-column field="unitsInStock" title="Units In Stock"></kendo-grid-column>
<kendo-grid-column field="quantityPerUnit" title="Quantity Per Unit"></kendo-grid-column>
<kendo-grid-column field="supplierID" title="Supplier" editor="dropdownEditor"></kendo-grid-column>
</kendo-grid>
<ng-template kendoGridEditorTemplate let-dataItem="dataItem" let-column="column">
<app-dropdown-editor [(value)]="dataItem[column.field]"></app-dropdown-editor>
</ng-template>
`
})
export class GridComponent {
public gridData: any[] = [
{ productName: 'Product 1', category: 'Category 1', unitPrice: 10, discontinued: false, unitsInStock: 100, quantityPerUnit: '1', supplierID: 1 },
{ productName: 'Product 2', category: 'Category 2', unitPrice: 20, discontinued: true, unitsInStock: 200, quantityPerUnit: '2', supplierID: 2 },
{ productName: 'Product 3', category: 'Category 3', unitPrice: 30, discontinued: false, unitsInStock: 300, quantityPerUnit: '3', supplierID: 3 }
];
public pageSize = 10;
public skip = 0;
public sort: any[] = [];
public state: State = {
filter: {
logic: 'and',
filters: []
}
};
}
以上代码示例中,我们创建了一个自定义的下拉编辑器组件DropdownEditorComponent
,并在网格列中使用了该组件作为编辑器。在网格列中,我们指定了editor
属性为dropdownEditor
,并在kendoGridEditorTemplate
中使用了app-dropdown-editor
组件。
这样,当用户编辑网格中的下拉列时,将会显示自定义的下拉编辑器,并且可以选择下拉选项。
请注意,以上示例中的代码是基于Kendo UI for Angular库的,如果你使用的是其他UI库或框架,可能会有所不同。
