Hello Support,

In the daily and weekly view from the ScheduleVies, the last appointments of daily appointments that span several days are not displayed.

Our customers often have daily appointments that span several days. When they switch to the daily or weekly view, the last day of these appointments is missing. We are now receiving daily complaints that the daily and weekly views are unusable. Please fix this bug as soon as possible. This error did not exist in the old Telerik library, but unfortunately we cannot reinstall the old library.

Thank you for your efforts.

Greetings marco

Currently, RadScheduleView supports keyboard navigation that works within the appointments area. To go outside of it, the control relies on the WPF default tab navigation logic (in this case allowed with Ctrl+Tab), but this doesn't work very well. Some elements (like the view definition buttons or input controls inside the appointment visuals) have their IsTabStop property set to False, which prevents the tab navigation.

Improve the accessibility of the control by allowing to navigate to the view definition buttons, the editors inside the appointment item and other interactive elements within the control (navigation buttons, calendar button, etc.). 

Consider implementing this via the existing NavigationBehavior if possible.

There are fragmented join geometries when drawing the joints between line segments that create very sharp angles. The fragments are presented by wrongly drawn long ray that start from the join.

This work this around, you can set the DefaultLineVisualGeometrySelector property of the LineSeries3D.

lineSeries.DefaultLineVisualGeometrySelector = new Telerik.Windows.Controls.ChartView.Geometry3DSelector();

Note that his workaround works because it removes the joints between the line segments. This prevents the origin of the problem, but it makes the line more jaggy.

Currently, the RadFileDialogs components show folder shortcuts, however, they are not fully supported. More specifically, interacting with them, such as mouse-double click, does not navigate to the respective folder.

In the meantime, this behavior can be achieved by subscribing to the Loaded event of the used file dialog type, in order to retrieve and cache the ExplorerControl in a field or a property. Then, you could subscribe to the PreviewMouseDoubleClick event of the used file dialog type and check whether the DataContext of the e.OriginalSource property is of the type of FileInfoWrapper. If it is and its IsShortcut property is true, set the CurrentDirectoryPath property of the cached ExplorerControl to the ShortcutLocation property of the FileInfoWrapper object.

The following code snippets showcase this approach when using the RadSaveFileDialog type:

//Caching the ExplorerControl instance
private ExplorerControl explorerControl;

//Retrieving the ExplorerControl instance
private void SaveFileDialog_Loaded(object sender, RoutedEventArgs e)
{
    RadSaveFileDialog radSaveFileDialog = (RadSaveFileDialog)sender;

    ExplorerControl explorerControl = radSaveFileDialog.ChildrenOfType<ExplorerControl>().FirstOrDefault();

    if (explorerControl != null)
    {
        this.explorerControl = explorerControl;
    }
}
//Navigation logic on double click of a shortcut
private void SaveFileDialog_PreviewMouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    FrameworkElement frameworkElement = e.OriginalSource as FrameworkElement;

    if (frameworkElement != null)
    {
        FileInfoWrapper fileInfoWrapper = frameworkElement.DataContext as FileInfoWrapper;

        if (fileInfoWrapper != null)
        {
            if (fileInfoWrapper.IsShortcut)
            {
                RadSaveFileDialog radSaveFileDialog = (RadSaveFileDialog)sender;

                this.explorerControl.CurrentDirectoryPath = fileInfoWrapper.ShortcutLocation;

                e.Handled = true;
            }
        }
    }
}

Currently, when you write down a web address (e.g. https://www.google.com) and move the caret outside of the address text (usually by pressing Space or Enter), the text is automatically wrapped in a hyperlink. Any further updates on the text won't update the underlying hyperlink address.

Add an option to auto-detect changes in the hyperlink text. This is valid only when the text matches the underlying link.

Exception after rapidly editing the document and then performing multiple undo operations.

NullReferenceException thrown on opening the CompletionListWindow when RadSyntaxEditor is hosted in a non-WPF application (usually WinForms) and there are no WPF Application and MainWindow initialized. 

This can happen if the RadSyntaxEditor for WPF is hosted in a WinForms application. In this scenario the System.Windows.Application.Current and its MainWindow are not initialized, which is what the IntelliPrompt positioning logic relies on.

Exception details:

System.NullReferenceException: 'Object reference not set to an instance of an object.'
> Telerik.Windows.Controls.SyntaxEditor.dll!Telerik.Windows.Controls.SyntaxEditor.UI.IntelliPromptBase.SetPosition(System.Windows.Point pointInScreen) Line 452 C#  Telerik.Windows.Controls.SyntaxEditor.dll!Telerik.Windows.Controls.SyntaxEditor.UI.IntelliPromptBase.SetPosition(System.Windows.Point pointInEditorPresenter, System.Windows.Point pointAboveTheCaret) Line 442 C#  Telerik.Windows.Controls.SyntaxEditor.dll!Telerik.Windows.Controls.SyntaxEditor.UI.IntelliPromptBase.SetPositionInView() Line 480 C#  Telerik.Windows.Controls.SyntaxEditor.dll!Telerik.Windows.Controls.SyntaxEditor.UI.IntelliPromptBase.InitializeIntellisense() Line 401 C#  Telerik.Windows.Controls.SyntaxEditor.dll!Telerik.Windows.Controls.SyntaxEditor.UI.IntelliPromptBase.Show(Telerik.Windows.Controls.SyntaxEditor.UI.CaretPosition caretStartPosition, Telerik.Windows.Controls.SyntaxEditor.UI.CaretPosition caretEndPositions) Line 211 C#
  Telerik.Windows.Controls.SyntaxEditor.dll!Telerik.Windows.Controls.SyntaxEditor.UI.IntelliPromptBase.Show() Line 182 C#

To work this around, you can initialize a new WPF application and MainWindow and create a hidden HwndSource for the MainWindow. This should happen before showing the WPF content in the WinForms application's code. 

 public Form1()
 {
     InitializeComponent();

     new System.Windows.Application();
     System.Windows.Application.Current.MainWindow = new System.Windows.Window();

     var parameters = new HwndSourceParameters("HiddenHost")
     {
         Width = 1, Height = 1,
         WindowStyle = unchecked((int)0x80000000) // WS_POPUP | WS_EX_NOACTIVATE
     };
     var hwndSource = new HwndSource(parameters);
     hwndSource.RootVisual = System.Windows.Application.Current.MainWindow;

      // other code here

     ElementHost host = new ElementHost { Dock = DockStyle.Fill };
     host.Child = wpfControl
     this.Controls.Add(host);
 }

Add an event that is raised when an exception is caught in a try-catch block in the internal logic of the QueryableCollectionView class. Currently, QueryableCollectionView is catching few exception. In some situations it could be helpful to listen for these situations.

The new API can be similar to the ExceptionRaised event of RadFileDialogs.

RadVirtualKeyboard starts a new Task which constantly checks the system culture and synchronizes this with the culture of the control. When the control gets unloaded or when the SynchronizeCultureWithSystem property is set to False, the Task's thread is stopped using the Cancel method of the associated CancellationToken, along with the ThrowIfCancellationRequested method. 

This throws an OperationCanceledException, which is the expected behavior to signal that the thread was canceled. However, the exception is marked as unobserved, which throws the TaskScheduler.UnobservedTaskException static event. This doesn't cause problems in the control or the host application, but the RadVirtualKeyboard can handled it better, so the exception is not marked as unobserved.

Hi Team,

I have set up SSO and it's great so far. I have a feature request that would make it even better, and solve many large enterprise needs, is to have a way to integrate SCIM based license provisioning as well.

Right now, you still do need to manage licensed users on the Manage Licensed Users portal. A License Holder or License Manager needs to add a Developer to the account and assign them a license.

With SCIM integration, we could better manage the users and licensing on a larger scale, with automation and oversight on the enterprise-managed SSO identity.

Thank you,

Kevin

I do have some feedback on this component. I love it, but of course there are some areas where improvement can be made. For instance, in the screenshot below, I have highlighted some words where improvement can be made.

  1. ‘1,2,3,5’ – Literals in SSMS are Red
  2. ‘ER – 100% OF MEDICARE’ – OF is highlighted in Blue. It is contained in a literal and shouldn’t be highlighted
  3. ISNULL – Is a function and should be highlighted in Blue
---- - It looks like that the tagger is only looking for 2 – only. If there are more than 2 in sequence, it doesn’t identify it as a comment and should
