ProgressChangedEventArgs.ProgressPercentage Property

Gets the asynchronous task progress percentage.

Namespace:  System.ComponentModel
Assembly:  System (in System.dll)

'Declaration
Public ReadOnly Property ProgressPercentage As Integer
'Usage
Dim instance As ProgressChangedEventArgs 
Dim value As Integer 

value = instance.ProgressPercentage

Property Value

Type: System.Int32
A percentage value indicating the asynchronous task progress.

The ProgressPercentage property determines what percentage of an asynchronous task has been completed.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the PictureBox.LoadProgressChanged 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 PictureBox named PictureBox1. Then ensure that the event handler is associated with the PictureBox.LoadProgressChanged event.

Private Sub PictureBox1_LoadProgressChanged(sender as Object, e as ProgressChangedEventArgs) _ 
     Handles PictureBox1.LoadProgressChanged

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "ProgressPercentage", e.ProgressPercentage)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "UserState", e.UserState)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"LoadProgressChanged Event")

End Sub
