How to launch a method after a cell value has been edited in ag-grid?

问题

I have this simple column:

Here's its definition:

{
      headerName: "Activité",
      field: "activite",
      editable: true,
       , cellClass: "cell-wrap-text"
      }  

Here's the method I want to launch every time the user enters a new input in that column.

  public UpdateActValue() {
      this.data.sendActToBia(this.params.data.activite);
      }  

Here are my questions:
1/ Are there any ag-grid "native" way to launch a particular method after a cell value from a column has been edited?
2/ Should I simply define a custom cell renderer and do all the necessary work there?
Thank you!

You can make use of the cellValueChanged event binding to detect changes in cell value.

On your component.html, you can simply bind the onCellValueChanged() method to the cellValueChanged event.

<ag-grid-angular 
.
.
(gridReady)="onGridReady($event)"
(cellValueChanged)="onCellValueChanged($event)"
>

And on your component.ts, you will define the onCellValueChanged() method, which will be fired every single time any cell value has changed.

onCellValueChanged(event) {
  // handle the rest here
}

I have just found a simple way to do this. I hope it helps.

In grid.component.html:

Add this inside the grid definition:

  (cellValueChanged)="onCellValueChanged($event)"

In the grid.component.ts: Define the method:

onCellValueChanged(params) {
    const colId = params.column.getId();
    if (colId === "activite") {
      this.data.sendActToBia(params.data.activite);
}
  }
