    We have a situation requiring multiple managers because we have user controls with multiple windows. There is a window manager in the user control to group these windows. When these user controls are added to the same page, the page ends up with multiple window managers, one from each user control.

    Are there any best practices around creating multiple RAD Window Mangers on a page? Does having multiple managers impose any penalties in performance / scale?

    Hello Praveen,

    The following help article treats using many RadWindowManagers on the same page and offers a solution - making sure you are using the correct manager instance to open you popups:

    Since you can have many instances of the same user control your JavaScript functions should not override each other, so they must have unique names and this is explained here: This should also apply to client-side event handlers.

    You can also avoid using RadWindowManagers in your user controls, since RadWindows can be declared and used directly on the page without a manager, you would simply need to use $find().show() with them instead of radopen() or
