Animation events

The following events can be subscribed to detect an XPTaskBarBox animation.

1. BeforeAnimation

2. AfterAnimation

BeforeAnimation - This event is fired before the XPTaskBarBox expands and collapses.

AfterAnimation - The event is fired after the XPTaskBarBox expands and collapses.

//Raises the BeforeAnimation event.
this.xpTaskBarBox1.BeforeAnimation += new EventHandler(xpTaskBarBox1_BeforeAnimation);
//Raises the AfterAnimation event.
this.xpTaskBarBox1.AfterAnimation += new EventHandler(xpTaskBarBox1_AfterAnimation);
//The event is raised before the TaskBarBox expands and collapses.        
void xpTaskBarBox1_BeforeAnimation(object sender, EventArgs e)
{
    this.richTextBox1.AppendText("\n Before Animation fired on XPTaskBarBox1");
}
//The event is raised after the TaskBarBox expands and collapses.
void xpTaskBarBox1_AfterAnimation(object sender, EventArgs e)
{
    this.richTextBox1.AppendText("\n After Animation fired on XPTaskBarBox1");
}

'Raises the BeforeAnimation event.
AddHandler xpTaskBarBox1.BeforeAnimation, AddressOf xpTaskBarBox1_BeforeAnimation
'Raises the AfterAnimation event.
AddHandler xpTaskBarBox1.AfterAnimation, AddressOf xpTaskBarBox1_AfterAnimation
'The event is raised before the TaskBarBox expands and collapses.        
Private Sub xpTaskBarBox1_BeforeAnimation(ByVal sender As Object, ByVal e As EventArgs)
   Me.richTextBox1.AppendText(Constants.vbLf & " Before Animation fired on XPTaskBarBox1")
End Sub
'The event is raised after the TaskBarBox expands and collapses.
Private Sub xpTaskBarBox1_AfterAnimation(ByVal sender As Object, ByVal e As EventArgs)
   Me.richTextBox1.AppendText(Constants.vbLf & " After Animation fired on XPTaskBarBox1")
End Sub

Note:

You would typically do this when you have to resize your form (or some other control in the form) based on the current size of the XPTaskBar control.
