# SSRM - Single Row Updates

This section demonstrates updating rows directly while using the Server-Side Row Model (SSRM).

## Updating Rows API

You can update a single row by using the row node `updateData` or `setData` functions.

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `updateData` | `Function` |  |  | Updates the data on the `rowNode`. When this method is called, the grid refreshes the entire rendered row if it is displayed. |
| `setData` | `Function` |  |  | Replaces the data on the `rowNode`. When this method is called, the grid refreshes the entire rendered row if it is displayed. |

> **Note**
>
> Setting row data will NOT change the row node ID, so if you are using `getRowId()` and the data changes such that the ID will be different, the `rowNode` will not have its ID updated.

## Updating Rows Example

The example below demonstrates a basic example, using the API's `forEachNode` function to iterate over all loaded nodes, and updating their version.

- **Set Data:** Sets the row data using `setData` and the grid refreshes the row, notably the cells won't flash with `enableCellChangeFlash`.
- **Update Data:** Updates the row data using `updateData` and the grid refreshes the row, notably the cells do flash with `enableCellChangeFlash`.

## Specific Row Updates

The following code snippet outlines the general approach of iterating through all loaded row nodes and then updating target rows with `rowNode.updateData(data)`:

```ts
this.gridApi.forEachNode(rowNode => {
    if (idsToUpdate.indexOf(rowNode.data.id) >= 0) {
        // arbitrarily update some data
        const updated = rowNode.data;
        updated.gold += 1;

        // directly update data in rowNode
        rowNode.updateData(updated);
    }
});
```

The example below demonstrates this snippet in action;

## Selected Row Updates

The example below demonstrates how to update all of the rows which the user has selected, note the following:

- The **Update Selected Rows** button will update the row version directly on the selected row nodes.
- The selected nodes are obtained using `api.getSelectedNodes()`, and are then individually updated.

#### Updating Selected Rows
