Subscribes an event handler to the [activeCellChanged] event.
The Ewa.EwaControl.add_activeSelectionChanged method subscribes an event handler to the activeCellChanged event. The activeCellChanged event fires when the active cell is changed (through mouse selection, cursor keys, return key, and so on).
The activeCellChanged event is distinct from the activeSelectionChanged event. The active cell is the cell that will receive input from the keyboard. The active selection is the range of cells that is currently selected. The active cell can change while the active range remains the same.
For example, when the Tab key is pressed within a selected range, the active cell changes but the selected range remains unchanged.
When the specified event handler for the activeCellChanged event is invoked, it is invoked with a single argument of type Ewa.RangeEventArgs. The Ewa.RangeEventArgs object contains information about the Ewa.Range object associated with the activeCellChanged event.
The following code example subscribes an event handler to the activeCellChanged event. The code also shows how to use the Ewa.RangeEventArgs to get information about the specified range. The code example assumes that you are working with an Excel Web Access Web Part on SharePoint Server 2013.
