If two connections are crossing one another at a connection point, the connection bridge (bow or gap) is not drawn.
This is reproducible only with the ConnecitonBridge property of RadDiagram set to Bow or Gap.

A possible workaround is to create a class that derives from RadDiagramConnection and override its CreateGeometry, where you can manually calculate and create the geometry of the connection line along with a connection bridge geometry.

Currently, you can change the size by setting the Width or Height property (based on the header's orientation) of the corresponding GroupHeader element. However, this change works only partially because of the built-in UI virtualization support. Make this work in all expected cases or introduce another API that will allow to change the size of the groups.

This issue is replicable in a setup which has two monitors and wit different DPI.
If a docking window is resized to a width over both monitors, when the window is more than a half on the monitor with lower DPI, it is not possible to dock it.

The TrayContextMenu is not displayed if the application does not have a MainWindow. If the menu's IsOpen property is set to true in the TrayContextMenuOpening event, however, the menu is shown as expected.
        private void NotifyIcon_TrayContextMenuOpening(object sender, CancelEventArgs e)
            if (!App.Current.MainWindow.IsLoaded)
                NotifyIcon.TrayContextMenu.IsOpen = true;

Currently, there is an internal API that determines whether partial matches can be selected or not. Provide public options to change this behavior. By default partial matches are selected.

In the meantime, the default behavior can be changed using reflection to set the CanAutocompleteSelectPartialMatches property of RadComboBox to False.

The style gallery is broken in the fluent theme and crashes the control
Last Updated: 20 Oct 2021 13:53 by ADMIN

The application hangs when you click on a Label element placed in the DropDownContent of RadSplitButton. In order to recreate this the content of the Label should contain an underscore character, thus enabling the access text WPF functionality. Also, the CloseOnPopupMouseLeftButtonUp property should be set to True.

This behavior can be reproduced with any element that is not derived from FrameworkElement. The issue in this case appear because when the access text is enabled, the Label control produces Run elements in its visual tree. The Run class doesn't derive from FrameworkElement, but from FrameworkContentElement, which causes the issue.

To work this around, use TextBlock instead of Label.

Some dialogs like ParagraphPropertiesDialog and SectionColumnsDialog have dependency properties for defining the width of the numerics. When creating implicit style, the value of these custom properties results in 0 and they are invisible in the UI.

Workaround: Set the value of the property in the custom style. For paragraph properties dialog:

<Style TargetType="rtb:RadParagraphPropertiesDialog" BasedOn="{StaticResource CustomStyle}" >
    <Setter Property="NumericWidth" Value="85"/>

When opening the ContextMenu and hovering over the first Item no Tooltip is displayed. Only when you move the mouse over another MenuItem on the same ContextMenu and then back to the first one the Tooltip gets displayed.

As a workaround, the telerik:RadToolTipService.ToolTipContent property can be used:

<telerik:RadMenuItem Header="I should display a tooltip" telerik:RadToolTipService.ToolTipContent="I am the tooltip that never shows" />

The template of the tooltip can also be modified to match the default tooltip style:

    <Style TargetType="telerik:RadMenuItem" BasedOn="{StaticResource RadMenuItemStyle}">
        <Setter Property="telerik:RadToolTipService.ToolTipContentTemplate">
                                Background="{telerik:FluentResource ResourceKey=PrimaryBackgroundBrush}"
                                BorderBrush="{telerik:FluentResource ResourceKey=BasicBrush}"
                        <ContentPresenter Content="{Binding}" Margin="5"/>

By specification, the InteractiveForm fields can have the same name if they are descendants of a common ancestor. Such fields are different representations of the same underlying field; they should differ only in properties that specify their visual appearance. When such a document is imported an ArgumentException: 'An item with the same key has already been added.' is thrown, which leads to non-editable fields in RadPdfViewer.

When a RadGridView cell has a validation error, a red border will appear around the cell. In this case, the top validation border is missing on the first row cells. As a workaround, you can move the ContentPresenters of the cells a little bit in the loaded event of the control.

private void RadGridViewView_Loaded(object sender, System.Windows.RoutedEventArgs e)
    var treeListView = sender as RadTreeListView;
    var editorPresenters = treeListView.ChildrenOfType<ContentControl>().Where(x => x.Name == "PART_ContentPresenter" && x.ParentOfType<GridViewCell>() != null);
    foreach (var item in editorPresenters)
        item.Margin = new System.Windows.Thickness(1);

Bug can be reproduced in PivotGrid => Olap Support in demo application.
Under all main categories in the designer, there is a folder called "Sets" that has the exact same content.

It either is mistakingly placed under each "category" or should be something that sits on top of them in a more global fashion.
