Three events are used when the SfDatePicker is in Dialog mode.

• Opened
• Closing
• Closed

Opened event

The Opened event occurs when the DatePicker is opened.

Closing event

The Closing event occurs when the DatePicker closes.

Drop-down close can be restricted by setting e.cancel to true.

Closed event

The Closed event was triggered, after the DatePicker was closed.
