public event EventHandler Deactivate;
member this.Deactivate : EventHandler 
Public Custom Event Deactivate As EventHandler

Event Type

EventHandler

Examples

The following code example demonstrates how to trap the Deactivate event to clear the SelectionList. This example is part of a larger example for the Form overview.

// When Form1 is deactivated
private void Form1_Deactivate(object sender, EventArgs e)
{
    count++;
}

' When Form1 is deactivated
Private Sub Form1_Deactivate(ByVal sender As Object, _
    ByVal e As EventArgs)

    count += 1
End Sub

Remarks

A form becomes inactive under the following circumstances:

  • When the ActiveForm property of the page is programmatically set to another form.

  • When the user navigates to a form through a Link control whose target is a form.

If neither of these actions occurs, the active form will never receive a Deactivate event. This event's position in the event chain makes it very important in resetting the child controls, data set, or global variables.
