Update a row in primeng table by double-clicking on it

Question

Update a row in primeng table by double-clicking on it

I am working with a primeng table that allows for editing rows by clicking on the pInitEditableRow button. However, I would like to initiate row editing by double-clicking on the row or any cell within that row. Unfortunately, Primeng table does not have this functionality built-in like it does with buttons. Is there a way to achieve this? Essentially, I want to trigger the same action as the pInitEditableRow button click when I double-click on the corresponding row.

<p-table [value]="products" dataKey="id" editMode="row" [tableStyle]="{'min-width': '50rem'}">
    <ng-template #header>
        <tr>
            <th style="width:20%">Name</th>
        </tr>
    </ng-template>
    <ng-template #body let-product let-editing="editing" let-ri="rowIndex">
        <tr [pEditableRow]="product">
            <td>
                <p-cellEditor>
                    <ng-template #input>
                        <input
                            pInputText type="text"
                            [(ngModel)]="product.name"
                            required />
                    </ng-template>
                    <ng-template #output>
                        {{product.name}}
                    </ng-template>

Original Answer

It appears that the "double-click-to-edit" functionality may not be built into PrimeNG by default.

However, you can achieve this behavior by utilizing a template reference (such as dt) and a ViewChild in your code.

To implement this feature, follow these steps:

Add a template reference (#dt in the example below) to your p-table component.
Use a ViewChild to access your table instance.
Create a custom event listener (onRowDblClick in the example below) for the dblclick event on each tr element.
Within your event listener, call this.dt.initRowEdit(product) to initiate row editing.

For example:

HTML

<p-table
  #dt
  [value]="products"
  dataKey="id"
  editMode="row"
  [tableStyle]="{ 'min-width': '50rem' }"
>
  <ng-template #header>
    <tr>
      <th style="width:20%">Name</th>
    </tr>
  </ng-template>

  <ng-template #body let-product let-editing="editing" let-ri="rowIndex">
    <tr [pEditableRow]="product" (dblclick)="onRowDblClick(product)">
      <td>
        <p-cellEditor>
          <ng-template #input>
            <input pInputText type="text" [(ngModel)]="product.name" required />
          </ng-template>
          <ng-template #output>
            {{ product.name }}
          </ng-template>
        </p-cellEditor>
      </td>
      <td>
        <div class="flex items-center justify-center gap-2">
          <button
            *ngIf="!editing"
            pButton
            pRipple
            type="button"
            pInitEditableRow
            icon="pi pi-pencil"
            (click)="onRowEditInit(product)"
            text
            rounded
            severity="secondary"
          ></button>
          <button
            *ngIf="editing"
            pButton
            pRipple
            type="button"

            (click)="onRowEditSave(product)"
            text
            rounded
            severity="secondary"

          <button

            type="button"
            pCancelEditableRow
            icon="pi pi-times"
            (click)="onRowEditCancel(product, ri)"
            text
            rounded
            severity="secondary"
          ></button>
        </div>

Update

PrimeNG provides support for table editing using directives such as pEditableColumn, pInitEditableRow, and more. You can refer to the specific section in the documentation for more information.

Note that when utilizing these directives, editing is triggered by a single click instead of a double click over an element.
