  • Setting a restriction zone

    In some scenarios it is desireable to have RadWindow confined to a particular area. This is useful when there is a user navigation interface and the windows should not obscure it.

    A similar effect can be achieved by using a FRAMESET or IFRAMEs, but in this approach it becomes difficult to synchronize the different page parts. Thus, to ease the creation of user-friendly interfaces, RadWindow provides the RestrictionZoneID property, which restricts window movement (and also maximize, minimize, resize functionality) to a particular area.
