Answer №1

To ensure each record is uniquely identified, it is important to have a property (e.g., id) for this purpose.

  1. Include the following function in your template:
[getRowNodeId]="_getRowNodeId"
_getRowNodeId(data) {
  return data.id;
}
  1. Assign an id to each object in your rowData.

  2. In the onGridReady event, use

    gridApi.getRowNode(id).selectThisNode(true)
    to select the first record.

this.gridApi.getRowNode(1).selectThisNode(true);

For more information, you can refer to the updated example on StackBlitz.
