Q2 2009 BETA (version 2009.2.616)

New Controls:

Rad Binary Image Icon

RadBinaryImage

RadBinaryImage gives you an easy way of showing an image stored as binary data in a database. The control can be used in any data bound control (Repeater, DataList, GridView, etc.) to display images which originate from binary image field in the data source. RadBinaryImage uses an internal http handler which streams the image from the binary source to the page in which it has to be visualized.

The most important properties of the RadBinaryImage control are presented in the list below:
  • DataValue - property which specifies the source field from which the data will be passed as a byte array
  • Height - specifies the height of the binary image
  • Width - specifies the width of the binary image
  • AlternateText - the text that will replace the image when it is not available/cannot be streamed
  • ToolTip - the text that will be displayed in a browser tooltip when you hover the image
  • AutoAdjustImageControlSize - scales the image based on explicitly set width/height dimensions to avoid stretch or blur effect when its original dimensions do not fit. The default value is true.
  • HttpHandlerUrl - can be used to specify the location of a custom http handler which extends the default RadBinaryImage http handler. When not set, RadBinaryImage has its own handler which is invoked through the common Telerik.WebResource.axd handler.
  • ImageUrl - applicable when no DataValue is specified to gracefully degrade to regular asp Image mode.
  • ImageAlign - specifies the image alignment inside its container.
RadCaptcha Icon

RadCaptcha

Telerik RadCaptcha is UI control that provides two major strategies for protection against automated form submissions:
  • Image With Modified Symbols (Captcha Image) - They are displayed in a form, and the user is required to input the symbols in a textbox. The Image is generated with an HttpHandler.
  • Automatic Robots Discovery - this strategy uses predefined rules which decide whether the input comes from a robot or not. At this point, there are two implemented rules that could be applied either separately or simultaneously.
    • Minimum form submission time - the presumption is that a human cannot input the fields in a form correctly for a time less than 3 seconds (this is set by default, and could be modified). If the submission is executed faster than the predefined value, it is assumed that the executor is a robot.
    • Hidden textbox in the form (the so-called "honeypot") - this rule requires the insertion of a textbox which is not visible when the form is styled. Still, it will be detected by a robot, and therefore if any data is entered, the executor is considered to be a robot.

Key features:

  • Three Modes for Protection - you can easily define which spam protection strategies to be used for spam protection. For maximum security, by default, all of them are used.
  • Set Custom Error Message - the error message that is displayed when the condition being validated fails. Depending on which protection strategy is used, the respective error message is displayed.
  • Background and Line Noise Level of the Captcha Image - you can easily control the background and the line noise of the Image by setting the respective value (None, Low, Medium, High or Extreme). The default level of the background noise is Low and of the line noise is None.
  • Font Family and Font Warp of the Catcha Image - you can easily choose which font family to be used for the Image text. Arial is used as a default value for the font family. Furthermore, the amount of random font warping to apply to the rendered text can be changed by setting the CaptchaFontWarp property. The default amount of font warping is Low.
  • Text Length and Possible Characters of the Catcha Image - the default length of the text is 5 characters, and the characters could be either letters or either numeric characters. Alternatively, you can choose what kind of characters to be used (only letters or only numeric characters), and change the length of the text.
  • Maximum time interval of the Captcha Image - the maximum number of minutes the Captcha Image will be cached and valid.
  • Minimum Timeout - minimum number of seconds the form must be displayed before it is valid. If you're too fast, you must be a robot. This is set when “Minimum form submission time” mode is used for Spam Protection.
RadListBox Icon

RadListBox

RadListBox is a powerful ASP.NET AJAX control to display a list of items. It allows for multiple selection of items, reorder and transfer between two listboxes. Drag and drop is fully supported as well. You can easily control the appearance by arranging the buttons in different layouts or changing their text. Icons and checkboxes are also supported within the listbox items.

The ListBox implements a highly efficient semantic rendering, which uses list items and CSS instead of tables. As a result the HTML output is significantly reduced, which dramatically improves performance.

RadListBox can be bound to all ASP.NET 2.0 declarative datasources (ObjectDataSource, XmlDataSource, SqlDataSource, etc) as well as the ASP.NET 3.5 LinqDataSource. Binding to XML strings as well as automatic database updates are fully supported.

The ListBox control has a rich client-side API and comprehensive set of events guaranteeing full control over various functions performed on the client. You can easily add/delete/update items at the client side and all the changes will be persisted on the server as well. The rich client-side API provides unbeatable performance and desktop-like experience.

RadListBox is shipped with a rich set of skins that allow you to easily build slick interfaces with the look-and-feel of Windows Vista, Office 2007, Outlook, etc. The skins can be easily switched using a single property.

RadXmlHttpPanel Icon

RadXmlHttpPanel

Telerik RadXmlHttpPanel is an UI control that serves as a container for rapid content loading. You can place diverse content on the RadXmlHttpPanel: rich user content, user controls or just about anything that could be added on a page.There are three ways for loading data on the RadXmlHttpPanel. These are: AJAX, Client Callback and WebService. Each of them has strong or weak points, so which one should be used depends solely on the scenarios the RadXmlHttpPanel is used in.

  • AJAX - It is the slowest of the three. This is happening because, when AJAX is used the controls affected are destroyed and recreated on the page, so the state of the controls is saved and posted back from the server, together with the content of the RadXmlHttpPanel. On the other hand the AJAX framework is flexible and universal. It can be used in many different scenarios.
  • Callback - When a client callback is used, only the RadXmlHttpPanel content is retrieved from the server, in contrast when using AJAX. The client state is not affected by the postback, so no need the state of the controls to be restored. Moreover, a handler for the OnServiceRequest event of the RadXmlHttpPanel should be specified to handle the data request which is not the case when using a WebService.
  • WebService - can be used to handle the data request of the RadXmlHttpPanel. The WebMethodPath and the WebMethodName properties should be set and the RadXmlHttpPanel automatically retrieves and loads the data. Similarly as in the Client Callback the client state is not affected.
    • The WebService and the Callback are maybe faster ways to load content, but their usage is specific and not as flexible as in the case when AJAX is used.

New Installer

  • RadControls for ASP.NET AJAX Visual Studio Extensions are now shipped with the controls, allowing the creation, configuration and upgrade of a Telerik Web (WebSite or Web Application)
  • A new model of toolbox item installation, allowing more stable toolbox items and improving the developer experience.
  • Improved installation/uninstallation time.
  • Improved status messages and progress information during the install
  • Following the new trends, the installer is now based on WiX.
  • And last, but not least, for your viewing pleasure – the improved UI.

Visual Studio Extensions

What’s New:

  • The Upgrade and Configure wizards now check for the Telerik.Web.Design assembly existence in GAC or in the Telerik.Web.UI assembly source location to help avoiding design time errors.
  • New template added - RadWindow login form.
  • AccessDataSource can now be used when creating DataBinding scenario pages.
  • XmlDataSource can now be used when creating DataBinding scenario pages.
  • When creating a DataBinding scenario page with SqlDataSource, there is a new wizard page asking if to save the connection string to the web.config file.

What’s Fixed:

  • When reconfiguring a WebSite with a file-based Telerik.Web.UI, which is in GAC, the IDE now displays a warning message that GAC reference is used instead and the assembly does not get copied to the local bin folder.
  • All templates are now reworked to use the new DataSourceSelector instead of having only SqlDataSource.
  • When creating a new project or reconfiguring an existing one the wizard now displays only assemblies with matching website Target Framework version (applicable for Visual Studio 2008). In Visual Studio 2005 only .NET 2.0 assemblies are displayed.
RadCalendar Icon

RadCalendar

What’s New:

  • Screen boundary detection for calendar/time view popup
  • Explicit expand popup direction setting for expand calendar/time view popup
RadEditor Icon

RadEditor

What’s New:

  • Added a new function to the editor server API - SetPaths(). Used to set the paths for one or more editor dialogs.

What’s Fixed:

  • Fixed: A problem with previewing animated GIF files in the Image Manager dialog in Internet Explorer
  • Fixed: A problem where the editor makes an extra request for the page if the table layout CSS property is empty
  • Fixed: Document Manager does not update the link text field properly when selecting files
  • Fixed: Custom dialog handlers could throw an exception if they need to access dialog parameters early in the page lifecycle
  • Fixed: Document Manager does not load correctly if you have added custom tabs to the Link Manager dialog
  • Improved localization support - allowing custom localization strings to be used in editor dialogs and fixing an issue with image/document manager localization
RadFormDecorator Icon

RadFormDecorator

What’s New:

  • New, faster rendering: The new RadFormDecorator is more flexible, as it covers a number of scenarios that the old rendering was not possible to accommodate in a seamless cross-browser manner. Examples are: changing the text of a button on the client-side with javascript, attaching event handlers to a button, providing additional styling to fieldset elements, etc. The new rendering works much faster because it takes heavy advantage of the browser’s CSS engine. The old rendering relied stronger on JavaScript because of its IE6 support. Now the core implementation targets newer browsers, and the code is branched for IE6 where necessary. The new rendering also performs much better with partial page updates (AJAX).
  • Support for styling SELECT (asp: DropDownList and asp:ListBox) elements.
RadFileExplorer Icon

RadFileExplorer

What's New

  • Eliminated the initial AJAX request to bind the grid. Grid data is rendered on the page now
  • Optimized rendering when paging is enabled (grid used to render 100 empty rows in HTML). Optimized initial load time - 1 Ajax request made instead of 2.
  • Added localization for the grid pager when AllowPaging is set to true. The new localization string in RadEditor.Dialogs is Common_GridPagerText
  • Remove unneeded context menu and toolbar items. If UploadPaths is empty, no Upload, New Folder, or Rename. If DeletePaths is empty - no delete.
  • Updated file explorer serialization to work in web applications without ReflectionPermission (modified Medium trust level)
RadGrid Icon

RadGrid

What’s New:

  • New GridBinaryImageColumn - each cell in a GridBinaryImageColumn contains an image streamed from a binary image source field (specified through the DataField property of the column). When used this column will show a RadBinaryImage control in view mode and RadUpload in edit mode to upload an image.
  • New GridImageColumn - can be used to display images by specifying image urls with options for sorting and filtering by field in the grid source specified through the DataAlternateTextField property of the column.
  • Keyboard support improvements - shortcuts for gaining focus, displaying the insertion form or refreshing the grid, improved navigation when editing/inserting records, options to toggle the active row cycle/multiple selection, built-in synchronization for active and selected grid row, etc.
  • NestedViewTemplate relations - the nested view template supports server-on-demand load mode and declarative hierarchy relations
  • Added support for indexing the GridGroupFooterItem by column uniquename.
  • Improvement: new implementation of Telerik.Web.UI.Grid.ScrollIntoView method in RadGrid client API

  • Fixed: RadNumericTextBox and RadDateInput should prevent page scroll when focused and value is incremented/decremented with the mouse wheel
  • Fixed: InputManager's empty message fails validation on readonly textbox set as target controls to a NumericTextBoxSetting
  • Fixed: RadTextBox EmptyMessage is editable if textbox has focus and press Ecs twice
  • Fixed: RadInputControl OnError does not reflect arguments.set_cancel properly
  • Fixed: RadInputManager setting value on blur event is not parsed correctly
RadMenu Icon

RadMenu

What’s New:

  • Implemented selection support

  • New event: OccurrenceDelete that is raised when a single occurrence is deleted, but no exception is created in its place
  • New localization strings for the advanced form title bar: AdvancedNewAppointment ("New Appointment"), AdvancedEditAppointment ("Edit Appointment")
  • Moved advanced form related properties to the AdvancedForm nested property - EnableAdvancedForm, EnableResourceEditing, EnableCustomAttributeEditing, EditFormDateFormat, EditFormTimeFormat. The old properties have been obsoleted.

What’s Fixed:

  • Fixed: AppointmentFactory is serialized in design-time in VS2008
  • Fixed: The header in week view displays wrong end date when the all-day row is hidden
  • Fixed: The ShowHeader="false" property does not work for Day and Month view groped by resource
