What’s New in DXperience 12.1
ASP.NET Navigation & Data Browsing Library
ASP.NET Pager - Page Size Selector
This release introduces a new page size selector UI for the ASPxPager. This feature benefits complex data-aware controls that use built-in pager functionality (the ASPxNewsControl, ASPxGridView, ASPxDataView, ASPxPivorGrid, ASPxTreeList). Activating the page size selector allows your end-users to dynamically change the number of data items (rows) displayed within a data control (such as a grid).

A page size selector is a pager section that consists of a descriptive label and a combo box containing page size values. Both elements - label text and value list - are customizable. You can easily compose a list of custom page size values and enable the All item providing the ability to show all data items at once. The page size selector section can be horizontally aligned to the left or right side of the pager.
The page size selector provides keyboard support. All page size change operations (such as showing/hiding a dropdown list, changing the page size, applying/canceling changes) can be performed using a keyboard as an alternative to a pointing device.
ASP.NET Splitter - Pane Auto Sizing
By implementing a couple of properties for splitter panes, we have provided support for pane auto sizing mode. You can now customize individual splitter panes, so they automatically resize to fit the size of their content when changed dynamically. For a pane, you can specify whether it should automatically change its width, height, or both.


ASP.NET Docking - New Zone Orientation Mode
A new dock zone orientation mode - Fill - has been added to the previously available Horizontal and Vertical modes. You can now specify a dock zone's orientation so that when a dock panel gets docked to the zone, it is automatically resized to fill the entire zone client area. In this instance, only one panel can be docked to a zone at a time.


ASP.NET PopupControl - Fade-in Animation
We have extended predefined animation types used to show a popup window with a new fade-in effect. Your popup window can now be displayed by fading it from transparent to opaque.
