Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the TextUpdate 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 ToolStripComboBox named ToolStripComboBox1. Then ensure that the event handler is associated with the TextUpdate event.

private void ToolStripComboBox1_TextUpdate(Object sender, EventArgs e) {

   MessageBox.Show("You are in the ToolStripComboBox.TextUpdate event.");
}
Private Sub ToolStripComboBox1_TextUpdate(sender as Object, e as EventArgs) _ 
     Handles ToolStripComboBox1.TextUpdate

   MessageBox.Show("You are in the ToolStripComboBox.TextUpdate event.")

End Sub
