RadRichTextBox

The RichTextBox control offers broad editing and formatting capabilities with unmatched performance and true Word-like experience.

RadTimeBar Beta

With RadTimeBar, your end-user can easily scroll and navigate through a large time period as well as select a certain date range. RadTimeBar is blazing fast even when working with a large set of data, providing smooth experience when zooming, scrolling or drilling the data. Use it independently, or combined with SparkLines to create rich data visualization.

RadDataForm

RadDataForm control will provide UI for displaying and editing properties of an object in a form layout. It will include collection navigation capabilities, basic data validation and will also respect key DataAnnotation attributes. As all other controls it will be compliant with the "lookless" concept and provide slick and highly customizable UI.

RadExpressionEditor

RadExpressionEditor provides end users the ability to write and edit complex formula expressions as a free form text. At the same time the new control gives the developers access to the structured data (in the form of a LINQ expression) about the entered expression. The primary use case for this component is integration within RadGridView and its LINQ based data engine, which allows unlimited runtime data shaping customizations.

RadMaskedInput

RadMaskedInput controls are designed for masking (controlling correct input) and formatting (displaying) culture specific values like numbers, currency, dates and text. The controls support data validation and provide great control over the input behavior, navigation, masked text (when in edit mode), display text (when not in edit mode).

• Added support for single image providers through the UriImageProvider class. Note that you can either specify single image for all zoom levels, or you can specify different image for every distinct zoom level. Also, note that this provider always should have its GeoBounds property set.
• Added support for the OSGB36 and EPSG:900913 projections to the EmptyProvider.
• Added support for built-in conversion between the following coordinate systems EPSG:4326 <-> OSGB36, and EPSG:4326 <-> EPSG:900913. It allows you to use shapefiles created for OSGB36 or EPSG:900913 (spherical Mercator with coordinates given in meters) with map providers which uses EPSG:4326 (Mercator with coordinates given as latitude and longitude) so it is possible to show such shapefiles “as is” over the BingMaps or OpenStreetMap imagery. The converter can be specified through the MapShapeReader.CoordinateConverter property (set it to OSGB36Converter or EPSG900913Converter).
• Added option to customize the commands in the CommandBar for every map provider (see the how-to section in the documentation for more information).
• Added option to restrict panning region for RadMap through the RadMap.GeoBounds property (see the how-to section in the documentation for more information).

• Added two new properties that control the geographical bounds of the information layer:
• InformationLayer.Region – Gets or sets the geographical region covered by the layer.
• InformationLayer.RegionMode - Gets or sets geographical region size mode. It can be “Static” or “Dynamic” (default). “Static” means that region has constant geographical location and size which are specified in the Region” property. “Dynamic” means that location and size of the region are calculated when items are added or removed to/from information layer. Note that if elements are grouped into several regions on the map then it is recommended to consider using several different information layers as well (one per region).
• Added support for MapLayer.ZoomRange attached property for the geographically restricted map providers.
• Added option to specify tile size different than the default 256x256 in the TiledMapSource class.
• Added support for culture settings to the map sources. Bing map tile sources use value from the RadMap.Language property to show map using the corresponding culture. Note that Bing imagery service does not provide support for all cultures - see http://msdn.microsoft.com/en- us/library/cc981048.aspx for the supported cultures.

What’s Changed:

• MapProviderBase.MinZoomLevel / MaxZoomLevel properties are obsolete – use RadMap.MinZoomLevel / MaxZoomLevel properties instead.
• RadMap.AllowedCommands property is obsolete – use the Commands property of the respective map provider and set the CommandDescription.IsAllowed property for the desired command to change its availability.
• RadMap. ZoomBarPresetsSettings property is obsolete now -- use Command.Text property for the corresponding zoom level command in the RadMap.MapZoomBar.Commands collection.
• Every provider has its own set of commands shown in its CommandBar now (you can access them via the Commands property of the respective provider).
• The InformationLayer is always geographically limited now and does not cover the whole surface of the map but just a part of it In order to improve precision – since InformationLayer.RegionMode is set to “Dynamic” by default, existing solutions should continue to work without any modifications.

Custom map provider architecture is not backwards compatible with previous versions

Here is a list of all provider-related changes:

• IMapProvider interface no longer exists.
• MapProviderBase class exists but it should not be used as a base class for custom providers any more. All custom map providers should inherit either from TiledProvider or ImageProvider.
• TiledProvider is a base class for map providers that show map as a sequence of tiles (e.g. BingMaps, OpenStreetMap).
• ImageProvider is a base class for providers that show map as a single image (UriImageProvider).
• Since all existing custom providers (prior to Q1 2011) show map as a sequence of tiles, they should be changed to inherit from the TiledProvider class. The only property which must be overridden in these custom providers is SpatialReference -- it should return the actual projection used by the provider (in all existing custom providers prior to Q1 2011 it should be MercatorProjection).

Here is a list of all map source-related changes:

• The map provider cannot be used as a map source by itself as it was allowed before.
• The logic which provides tiles must be moved to separate class – map source.
• All map source classes should inherit either from TiledMapSource, or ImageMapSource classes and override methods depending on the specific map source type.
• TiledMapSource is a base class for map sources that return map tiles (that includes all BingMaps sources: aerial, road, birds eye, and all OpensStreetMap sources: Mapnik and Osmarenderer).
• ImageMapSource is a base class for map sources that return single map image.
• Since all existing providers prior to Q1 2011 show map as a sequence of tiles, their new map source classes should inherit from the TiledMapSource class and meet the following requirements:
• It should override the Initialize method.
• It should override the GetTile method and existing custom logic should be moved here.
• It should call RaiseInitializeCompleted method when the respective custom provider is initialized (in case of simple providers it is enough to call this method from the override Initialize method).

What’s Fixed:

• Fixed issue with corrupted tile image throwing exception.
• Fixed issue with using MapPath instances in the DynamicLayer in specific scenarios.
• Fixed application freeze when the center and zoom level of map are changed a few times quickly.
• Fixed ItemTemplateSelector on an informationlayer not working.
