Pass KeyDown Event To Other Control

Question

Hi, I've got a TextBox control on a form, then directly below it a ListBox control. Is there an easy way of passing the KeyDown event on the TextBox directly to the ListBox? i.e. if a user presses the Up/Down/Page Up/Page Down controls on a TextBox, it'll advance and retreat the selection in the ListBox accordingly. I've wrote the code to detect for specific keys on the TextBox, then modify the selection according to the key pressed. Was just wondering if there's a more efficient way of doing it. Thanks in advance! Chris
