Grid Events

This is a list of the events that the grid raises. You can register callbacks for these events through the GridOptions interface.

The name of the callback is constructed by prefixing the event name with on. For example, the callback for the cellClicked event is gridOptions.onCellClicked.

Selection

Editing

Sort and Filter

Row Drag and Drop

Columns

Miscellaneous

Event Properties and Hierarchy

Below shows the event hierarchy and properties. All properties are inherited. For example the CellValueChangedEvent interface has the following properties:
