Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ToolTip.Popup 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 ToolTip named ToolTip1. Then ensure that the event handler is associated with the ToolTip.Popup event.

private void ToolTip1_Popup(Object sender, PopupEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "AssociatedWindow", e.AssociatedWindow );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "AssociatedControl", e.AssociatedControl );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "IsBalloon", e.IsBalloon );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ToolTipSize", e.ToolTipSize );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Cancel", e.Cancel );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "Popup Event" );
}

Private Sub ToolTip1_Popup(sender as Object, e as PopupEventArgs) _ 
     Handles ToolTip1.Popup

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "AssociatedWindow", e.AssociatedWindow)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "AssociatedControl", e.AssociatedControl)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "IsBalloon", e.IsBalloon)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ToolTipSize", e.ToolTipSize)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Cancel", e.Cancel)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"Popup Event")

End Sub

Remarks

The type of window used for the ToolTip is specified in the ToolTip.IsBalloon method of the ToolTip class.
