NEW RadDock

RadDock is a brand new component in the Telerik toolbox, which will supersede the old DockingManager. Features at a glance:
  • The most advanced docking system on the market
  • Completely new layout system, pluggable per RadSplitContainer basis. Virtually any layout scenario may be achieved in a few lines of code
  • Completely new drag-and-drop mechanism, fully transparent and highly customizable API, based on services
  • Revamped Quick Navigator (CTRL+TAB window list) with extensible keyboard support and active panel preview
  • Entirely new re-dock support, based on services. Each dock window may be restored to exactly the same place it was occupying previously
  • Transaction-based docking model, allowing for multiple tasks to be stacked and executed at once
  • Document drag-and drop and re-order
  • State transitions like in Visual Studio - Dockable to Tabbed Document to Floating, etc.

Common DockingManager API vs RadDock Q2 2009 API

class DockableWindowCollection class DockWindowCollection

interface IDockable interface IDockWindow
(generally DockWindow class can be used)
dockingManager.SetDock(window, position) radDock.DockWindow(window, position)
dockingManager.Float(window) RadDock.FloatWindow(window);
dockPane.DockTo(anotherWindow, state) radDock.DockWindow(window, DockPosition.Bottom);
dockWindow.DockState = DockState.Floating;
or
dockWindow.DockState = DockState.AutoHide; etc
radDock.DockWindow(dockPane, anotherWindow , state)
dockingManager.DockingStateChanged radDock.DockStateChanged
dockingManager.DockingStateChanging radDock.DockStateChanging
dockingManager.Hide(dockWindow, true); dockWindow.DockState = DockState.AutoHide;

+ overloads available
dockingManager.SaveXML(fileName) SaveToXml(fileName)
+ overloads available
dockingManager.Reset() radDock.Clear()

dockPane.TabStripVisible = false; dockWindow.TabStrip.TabStripElement.Visibility = ElementVisibility.Collapsed;
DockWindow.Activated event radDock.ActiveWindowChanged/Changing

Upgrading from DockingManager to RadDock

The new RadDock comes with an upgrade tool within Visual Studio which will help you move from the old DockingManger to the new RadDock. It converts DockingManger's XML layout serialization to the new XML structure of RadDock, so that you do not have to recreate the structure yourself.
NOTE: You may need to remove/redo any custom code related to the docking control, because it may not work with the new docking component. Also, remove any workarounds related to the old DockingManager.

  1. Download the beta version of RadDock and install the package. The package contains all the controls from RadControls for WinForms Q1 2009 SP1, and a new assembly for the new RadDock Beta (Telerik.WinControls.RadDock.dll). This means that both versions of RadDock (old and new) are fully functional and can be used in the same application.
  2. Once the installation completes, feel free to review the RadDock Examples (Start --> Programs --> Telerik --> RadControls for WinForms Beta --> Run Demos).
  3. Back up your project.
  4. Include/update the references of the following assemblies in your application:
    • Telerik.WinControls.dll
    • Telerik.WinControls.UI.dll
    • Telerik.WinControls.RadDock.dll (new RadDock)
    • Telerik.WinControls.Docking.dll (old DockingManager)
    • TelerikCommon.dll
  5. Restart Visual Studio to ensure that all references are updated (sometimes VS.NET locks the assemblies and they are not updated properly).
  6. Open a form with the old docking and right-click on it in design time.
  7. From the context menu select the DockingManager control (it is necessary to select DockingManager, because the option to convert to RadDock is in its designer). The DockingManager will get selected, and the option to open the smart tag should appear.
  8. Open the smart tag - you will see a new option to convert to the new RadDock.

NEW RadSplitContainer

The Telerik SplitContainer for Windows Forms is a complicated layout control, which emerged from the new RadDock's layout base (see above). RadSplitContainer is a composite control which allows you to add many container panels to a form, separated by splitter(s). It is very handy for creating complex user interfaces where a selection in one panel determines what objects are shown in another panel. The splitter makes it very easy for users to resize the panels to fit their personal liking. What makes RadSplitContainer unique are several features, which are not available in Microsoft's SplitContainer control:

  • As with the default SplitContainer, nested containers are supported by RadSplitContainer, however you are not limited to the initial two panel setup - you can have as many panels in a container as needed without having to nest more containers;
  • All splitters used in RadSplitContainer can be fixed unlike the default toolbox control which is limited to just one fixed splitter;
  • The appearance of RadSplitContainer can be skinned to your liking. For your convenience, several themes are offered out of the box;
  • RadSplitContainer offers extended design-time support with the most common options included directly in the smart tag:
    • You can add new horizontal or vertical panel(s) to the selected container;
    • You can set the orientation of the splitter (horizontal/vertical);
    • You can fix the splitter to restrict panel resizing.

  • Aqua theme added
  • Export to Excel takes significantly less memory and the performance is improved. The entire class ExportToExcelML has been rewritten to be better arranged and optimized

  • New ExcelCellFormatting event has been added which allows additional formatting such as adding a border, setting alignment, setting text font, setting colors, changing cell value, etc.
  • New ExcelTableCreated event has been added. In conjunction with the new public method, AddCustomExcelRow allows adding and formatting new custom rows on the top of the table which is created from RadGridView data

  • Export to Excel Fixed: Format Types were skipped when there is more than one visual base
  • Export to Excel Fixed: All visual settings are lost if there is not at least one visible base row (a row whose visual appearance comes from a theme). Now the exporting skips the base theme settings but applies all other visual settings such as grid header row formatting, conditional formatting, and alternating row settings
  • Export to Excel Fixed: Out of memory exception when exporting large numbers of data.
  • Breaking Change in Export to Excel: The constructor of ExportToExcelML class has a parameter of type RadGridView. You cannot make an instance of ExportToExcelML class without specifying the grid which will be exported. The old constructor - without a parameter - is marked as obsolete.

  • Breaking Change in Export to Excel: The RunExport method now takes only one parameter: file name. All other parameters such as RadGridView, SheetMaxRows, and ExportVisualSettings are ExportToExcelML public properties with default values. The old method is marked as obsolete.
  • Breaking Change in the Editor's system: Now all editors are not RadElements. They implement the IInputEditor interface or inherit from BaseGridEditor. You should use the EditorElement property to access the underlying RadElement.
  • Breaking Change in the Editor's system: Now the CellEndEdit event fires after finishing the editing process. You should use the CellValidated event to access row properties (e.g Tag) when adding new row.
