The ASPxPopupControl control supports an adaptive mode allowing you to build page layouts that fit a browser window's width. In adaptive mode, the popup control changes its size according to a user's device type and page resolution.


To enable the adaptivity mode for ASPxPopupControl, use the PopupControlAdaptivitySettings.Mode property that provides the following modes:

  • Always - Adaptivity mode is always enabled.

  • OnWindowInnerWidth - Adaptive mode is enabled when the browser window inner width is less than or equal to the value the PopupControlAdaptivitySettings.SwitchAtWindowInnerWidth property specifies

The following settings control the popup control's size in adaptive mode:
