some controls. so we can easily show hide panel child controls by setting panel property. we can also enable disable
all asp.net controls that exists in a panel control as child control. this example demonstrate you how can we enable or disable panel
container child controls programmatically. for better understanding we create two button with click event and a panel
container with inside other controls. when you click the specific button it enable or disable panel child controls.
