Control.HandleCreated Event

Occurs when a handle is created for the control.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)
[BrowsableAttribute(false)]
public event EventHandler HandleCreated

A handle is created when the Control is displayed for the first time. For example, if a Control is created that has Visible set to false, the HandleCreated event will not be raised until Visible is set to true.

For more information about handling events, see Consuming Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the HandleCreated 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 a type that inherits from Control, such as a Button or ComboBox. Then name the instance Control1 and ensure that the event handler is associated with the HandleCreated event.

private void Control1_HandleCreated(Object sender, EventArgs e) {

   MessageBox.Show("You are in the Control.HandleCreated event.");

}
