CommonControls (Replacement of the MS common controls)

[Hosam AL Dein]

It's a very bad idea to make some code involving the child usercontrol in the host usercontrol inside the UserControl_Initialize() event. The UC Ambient.UserMode property is not meaningful at that place. Please set your code that involves the child usercontrols in the UserControl_ReadProperties()/UserControl_InitProperties().
