PictureBox.LoadCompleted Event

Occurs when the asynchronous image-load operation is completed, been canceled, or raised an exception.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public event AsyncCompletedEventHandler LoadCompleted
/** @event */
public void add_LoadCompleted (AsyncCompletedEventHandler value)

/** @event */
public void remove_LoadCompleted (AsyncCompletedEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

The LoadCompleted occurs only when the image is loaded asynchronously by using one of the LoadAsync methods, and WaitOnLoad is false. If the image-load is canceled by calling the CancelAsync method the Cancelled property of the AsyncCompletedEventArgs will be set to true. If an exception or error occurs during the load process, it will be caught and the Error property of the AsyncCompletedEventArgs will contain the exception information.

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 LoadCompleted 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 System.Windows.Forms.MessageBox.Show with System.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 PictureBox named PictureBox1. Then ensure that the event handler is associated with the LoadCompleted event.

private void PictureBox1_LoadCompleted(Object sender, AsyncCompletedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Cancelled", e.Cancelled );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Error", e.Error );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "UserState", e.UserState );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "LoadCompleted Event" );
}
