The ASPxPopupControl allows you to display the content of other web pages by specifying their URLs. The control’s ContentUrl property is used to load a specific web page into the ASPxPopupControl.
In this demo, the ASPxPopupControl's ContentUrl property is assigned with the navigation location of a specific web page that emulates a feedback form. The page content is loaded into the popup control's window automatically.
This demo also illustrates the resizing feature of the ASPxPopupControl. This feature is enabled by setting the AllowResize property to true. The popup control's window can be resized by using the size grip or by dragging the window's edges.
