The default popup window (or all popup windows from the ASPxPopupControl.Windows collection) is aligned vertically on the y-coordinate of the mouse cursor position by default. Use the PopupVerticalAlign property to set the window alignment relative to the corresponding element specified by the ASPxPopupControl.PopupElementID (PopupWindow.PopupElementID) property, or to display the window at the center of the browser’s window.
Note
Use the HorizontalAlign and VerticalAlign properties to align a popup in adaptive mode.
This example demonstrates the following capabilities of the ASPxPopupControl when its popup window is used in modal mode:
The ShowPageScrollbarWhenModal property allows the browser’s vertical scrollbar to be displayed providing users with a capability to scroll the document content while the modal popup window is being shown;
The AutoUpdatePosition property controls whether the popup window’s position should be automatically recalculated after performing some popup window resizing or document scrolling operations.
