Event Context
Inside a Workbook action's instruction list, @Event exposes the event payload that triggered the action.
Common properties
@Event.Data.<Field> -- field on the row that was clicked or acted on
@Event.Sender.ColumnName -- column where the action originated
@Event.Sender.ActionName -- name of the menu action or button
@Event.Selection.Rows -- array of selected rows
@Event.Selection.Cells -- selected cells
Example
SetParamValue("@param1", @Event.Data.customerId);
@Var[Last Row Clicked] = @Event.Data;
@Var[Last Row Clicked].ProductID = @Event.Data.ProduktID;
In JavaScript action handlers
In JavaScript action handlers (2025.5+), use Event without the @ prefix:
SetParamValue("@param1", Event.Data.customerId);
const rows = Event.Selection.Rows;
