DateTimePicker.ValueChanged Event

Occurs when the Value property changes.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public event EventHandler ValueChanged

User input is validated before this event is raised. This event is not raised when the entered date is earlier than MinDateTime or later than MaxDateTime.

For more information about handling events, see Handling and Raising Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ValueChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type DateTimePicker named DateTimePicker1. Then ensure that the event handler is associated with the ValueChanged event.

private void DateTimePicker1_ValueChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the DateTimePicker.ValueChanged event.");

}
