What causes the error "Angular 2 checkbox params.setValue is not functioning properly"?

import { Component } from '@angular/core';

import { GridOptions, RowNode } from 'ag-grid/main';
import { ICellRendererAngularComp } from 'ag-grid-angular';


@Component({
    selector: 'qrp-drop-down-selector',
    template: `
    <input type="checkbox" [checked]="params.value" style="margin-top: -6px;" (change)="params.setValue($event.target.checked ? true : null)">
    `
})
export class QrpDropdownEditorComponent implements ICellRendererAngularComp {
    private params: any;

    agInit(params: any): void {
        this.params = params;
    }
}

I came up with a component similar to this. However, when I added the checkbox, I encountered the error self.context.params.setValue is not a function. What mistake did I make in this scenario?

Answer №1

When Angular is searching for an object that has the setValue() method, it encounters difficulties in locating it. A possible solution would be to implement code similar to this:

@Component({
    selector: 'qrp-drop-down-selector',
    template: `
    <input type="checkbox" [checked]="params.value" style="margin-top: -6px;" (change)="setValue($event.target.checked ? true : null)">
    `
})
export class QrpDropdownEditorComponent implements ICellRendererAngularComp {
    private params: any;

    agInit(params: any): void {
        this.params = params;
    }

    setValue(val: boolean) {
       this.params = val;
    }
}
