Hi Team,

having a "Signature" component in your WPF package like you have in your Blazor package will be very interesting.

The following exception is thrown when changing the theme of an element with the StyleManager runtime:
Cyclic reference found while evaluating the ThemeStyle property on element 'Telerik.Windows.Controls.Gauge.Needle'.

This only occurs in some themes, such as Fluent, Crystal, and Office2016.

Can be reproduced in the WPF demo (Windows8 theme): the error description tooltip appears on the left of the control and with the red arrow on the left (see attachment). The tooltip should appear on the same side of the red adorned element (the red triangle, top right corner) and the tooltip arrow should point the control.

I have a Pie chart like this:

                 <telerik:RadPieChart Palette="Arctic">                    
                        <telerik:DoughnutSeries ItemsSource="{Binding GraphedStatistics, Mode=OneTime}" ValueBinding="Previous" ShowLabels="True">
                            <telerik:DoughnutSeries.LabelDefinitions>
                                <telerik:ChartSeriesLabelDefinition>
                                    <telerik:ChartSeriesLabelDefinition.Template>
                                        <DataTemplate>
                                             <StackPanel Opacity="{Binding Value, Mode=OneWay>
                                                <TextBlock Text="{Binding DataItem.Name}" HorizontalAlignment="Center" Foreground="{StaticResource textBlockForeground}"/>
                                                <TextBlock  HorizontalAlignment="Center"  Foreground="{StaticResource textBlockForeground}">
                                                    <Run Text="{Binding Value, Mode=OneWay, StringFormat=' {0:#}'}"/>
                                                    <Run Text="{Binding Percent, Mode=OneWay, StringFormat=' ({0:#}%)'}"/>
                                                </TextBlock>
                                            </StackPanel>
                                        </DataTemplate>
                                    </telerik:ChartSeriesLabelDefinition.Template>
                                </telerik:ChartSeriesLabelDefinition>
                            </telerik:DoughnutSeries.LabelDefinitions>
                        </telerik:DoughnutSeries>

If I generate a pie or doughnut chart the Percent is not updated when I update a value in the bound data source (GraphedStatistics).  Note: I am updating the observable collection not replacing it. The graph is redrawn correctly and Value updates correctly.

The version is 22.1.1.0 (not in the options below)

Updated (See that 'Monaco' is the same percentage as before the update,  Value is correct and the UI Graph is correct but the segment is clearly not 26%)

Selecting a pinned row or column results in wrongly selected indexes. 

Steps to reproduce:

Case #1: 

1. Pin a row

2. Select the pinned row 

result: a wrong row is selected

Case #2: 

1. Pin one column 

2. Select a cell from the pinned column 

Result: The visual selection is for the first unpinned cell. The selected indexes are wrong too. The Column index is always 0 

Setup: In a WPF Windows Desktop application project, use a RadTabControl with 2 tabs, Tab 1 and Tab 2. Add a RadDocking and some Panes to Tab 1.

Run the application and do:

• Put one RadPane into floating mode
• Go to Tab 2
• Notice how the floating pane is hidden (good)
• In Windows, select Switch User, but when the login screen is shown just re-enter your credentials to get back into your Windows session
• Notice how the floating pane is visible despite the application still showing Tab 2  (not good)
• Move the pane a bit, crash

I've attached a sample project showing the problem, with similar instructions as above. Tested with both 2021.3.1123 and 2022.2.622.

Please advice!

Latest version of wpf ui on NET6 I receive this error with Office2019 theme, also tested with Office2016 theme and there is no error.

System.Windows.Markup.XamlParseException: "Die Angabe eines Werts für "System.Windows.Markup.StaticResourceHolder" führte zu einer Ausnahme."
Exception: Die Ressource mit dem Namen "RepeatButtonStyle" kann nicht gefunden werden. Bei Ressourcennamen wird die Groß- und Kleinschreibung berücksichtigt.

Diese Ausnahme wurde ursprünglich von dieser Aufrufliste ausgelöst:

    System.Windows.StaticResourceExtension.ProvideValue(System.IServiceProvider)
    MS.Internal.Xaml.Runtime.ClrObjectRuntime.CallProvideValue(System.Windows.Markup.MarkupExtension, System.IServiceProvider)

I have a RadComboBox which is causing the error. When I remove this element, error is gone. Error only happens when I click on the drowdown. The error happens before dropdown open.

<ResourceDictionary Source="/Telerik.Windows.Themes.Office2019;component/Themes/Telerik.Windows.Controls.xaml" />

        <ResourceDictionary Source="/Telerik.Windows.Themes.Office2019;component/Themes/Telerik.Windows.Controls.RibbonView.xaml" />

So, if there is a solution to this, I haven't found it yet after scouring the documentation and the internet.

Using your example in the WPF Demo, I created a custom object for my items that I bind to the RadNavigationView.ItemsSource. Yours was called NavigationItemModel. Mine is called ShellMenuItem. ShellMenuItem inherits from UserControl, and implements INotifyPropertyChanged, and ICommandSource. All bindings to my properties are wired up in the xaml and work great (EXCEPT FOR THE ISEXPANDED PROPERTY. Next, I have several properties that are pulled from a database, or can be set programmatically in code, like Id, ParentId, Header, NodeType, TargetPageType (Page, Window, etc), TargetViewModelType, etc... Just standard properties. These are so I can programmatically send these dynamic items menu items, pulled from a database, to the correct View and ViewModel. ALL OF MY PROPERTIES WORK FINE, and when I click on a menu item, if it is a page, it opens in the frame, if it is a window, it opens a window, etc... Everything works fine, except the IsExpanded. So, here is the issue. I have a property on ShellMenuItem named IsExpanded. When I try to set this property, the ShellMenuItems do not collapse or expand. Again, I have INotifyPropertyChanged implemented.

On the form, I have a toggle button to expand/collpase all items in the RadNavigationView. I have it's Checked event bound to a command in my ViewModel. 

<ToggleButton Content="TestExpandAll">
     <i:Interaction.Triggers>
          <i:EventTrigger EventName="Checked">
               <i:InvokeCommandAction Command="{Binding ElementName=_this, Path=DataContext.CmdExpandMenus}" PassEventArgsToCommand="True" />
          </i:EventTrigger>
      </i:Interaction.Triggers>
</ToggleButton>

public ICommand CmdExpandMenus { get { return new RelayCommand<RoutedEventArgs>(OnExpandMenus); } }

This fires correctly in my code, at which point I loop through the RadNavigationMenu's ItemsSource and set each property to IsExpanded = true; As shown below. The button should expand all items if the togglebutton state IsChecked, else, it should collpase all items. I have also tried to loop through the actual bound list which likewise, does not work. I can not find a way to get at the entire list of RadNavigationViewItems or even cast my items to a RadNavigationViewItem, even though the ItemContainerStyle's target type is RadNavigationViewItem. There has got to be a simpler way to achieve this. 

        private void OnExpandMenus(RoutedEventArgs? e)
        {
            //foreach (var item in this.StaticMenuItems)
            //{
            //    item.IsExpanded = true;
            //}

            foreach (var shellMenuItem in this.MainMenu.ItemsSource)
            {
                var itm = shellMenuItem;
                var itmType = itm.GetType();
                //itmType is ShellMenuItem
                var menuItem = shellMenuItem as ShellMenuItem;
                //var targetType = this.MainMenu.ItemContainerStyle.TargetType;
                //targetType is RadNavigationViewItem
                menuItem.IsExpanded = true;
            }
        }

I have easily achieved this effect on many other controls, and you even have predefined Methods to perform this on controls such as RadTreeViewList.

    void treeListView_DataLoaded(object sender, EventArgs e) 
    { 
        treeListView.DataLoaded -= treeListView_DataLoaded; 
        treeListView.ExpandAllHierarchyItems();    
    } 

Can you add a method to the RadNavigationView to ExpandAllHierarchyItems(true/false) or just add 2 methods...

ExpandAllHierarchyItems() and CollapseAllHierarchyItems()

If this is not feasible, then you should update your demo to show how to accomplish this with a custom menu item. Im sure I could make my ShellMenuItem inherit directly from RadNavigationViewItem but in my control library, I dont have any references to Telerik because there are applications that use ShellMenuItem that do not use Telerik at all, and we shouldnt have to make our generic controls inherit from a 3rd party control to make this work. It seems to me that if you have a control that allows a hierarchy of items, and those controls/classes can be expanded or collapsed, then you should ALWAYS add the methods above to those controls/classes. Or perhaps you could create an interface named IExpandable, and any control that you guys create that can be expanded/collapsed, could implement that interface and have access to the ExpandAll/CollapseAll funtionality.

Hello,

When I do the following:

and I assign this style to my dynamically created columns from a behavior attached to the RadGridView, the style of the tooltip is the same as the style of the header.

They seem to share the same style, so that when I change one property on the header, the tooltip gets the same, and vice-versa.

Do you repro? I'm on version 2020.3.1020.45.

Thanks,

Arthur
