It would be very useful for us if the RadWebCam control (WPF or WinForm) could support ONVIF Profile S

Thanks

We use a RadTileList as our main navigation component. Today we noticed that our app's memory consumption only ever increases when opening modules and never decreases when closing them. When tracing memory usage with DotMemory (using the Key retention paths feature), I noticed that the retention path to the leaked module viewmodels seems to be rooted in the RadTileList component (see the attached screen shot).

A few implementation details:

- We are wrapping our modules in a class called "OpenedModule" (as you might guess from the attached image)

- The RadTileList is databound to an ObservableCollection<OpenedModule> via its ItemsSource

- We do not use grouping

- Closing a module results in the module's "OpenedModule" instance being removed from the ObservableCollection

This is the xaml we use to instantiate the TileList:

<telerik:RadTileList 
    x:Name="NavigationRadTileList"
    ItemsSource="{Binding OpenedModules, Mode=OneWay}" 
    CanUserSelect="False"
    TilePlaceHolderSide="90"
    behaviors:DisableTileListRightClickBehavior.IsEnabled="True"
    ItemTemplate="{StaticResource NavigationTileListTemplate}">
    <telerik:RadTileList.Resources>
         <Style TargetType="{x:Type telerik:Tile}" BasedOn="{StaticResource NavigationTileStyle}" />
    </telerik:RadTileList.Resources>
</telerik:RadTileList>

Judging by the result from dotMemory, it looks like the TileGroup's children are somehow cached in an ordered list which is not updated when an item is removed?

Issue : Currently the Free Trial / Download page states "Over 120 UI controls" yet the product pages states "over 140".

Obviously "Over 120" is technically correct, however, 140 is more accurate, sounds better & increases consistency across the site.

The same issue also applies to the "UI for WinForms" description and its respective product page.

Good afternoon,

When we add a new child element to the RadDiagram(see attach file), the diagram automatically optimizes their layout. After the chart is updated, the new element and its parent are automatically moved to the left side. How to make them stay in their places?

There is a small discussion of this problem on the forum.

I've downloaded the latest Sample Application for Terlerik UI for WPF R1 2021 SP1

When I try to select the RibbonView sample I get a MessageBox with message "Exception has been thrown by the target of an incovation" and the sample does not load.  All other samples work fine.

After defining my colors in the Telerik color theme generator vs wasn't recognizing the emitted code as valid. I had to explore the Intellisense suggestions and try different variations until I arrived at the correct solution:

I'm not sure if this has to do with versioning differences or is a general case. Regardless, I figured I'd let the Telerik team know.

Best,

Nick

2. Click the "Disable Controls" checkbox
   • => Observe the controls become disabled
3. Switch to Simplified Ribbon
4. Click the "Disable Controls" checkbox
   • => Observe the controls are not disabled.

https://www.telerik.com/forums/bug-maybe-xdg0047-error-the-following-type-was-expected-ifilteringcontrol

I've just updated Telerik and are now getting this compile time error:

Severity Code Description Project File Line Suppression State
Error XDG0047 The specified value cannot be assigned. The following type was expected: "IFilteringControl". Modelkatalog.Client C:\develop\data-tool-modelkatalog\Modelkatalog.Client\Controls\List\CarVariantsList.xaml 1

I'm getting this error from 2 XAML documents that both implement a custom Fitler for the RadGridView 

I didn't get this error before, and I'm still able to compile and run the project - which kind of defeat the purpose of [Severity: Error]

To whom it may concern,

In our MVVM-project, we are using a derived implementation of the RadRibbonWindow to add some customized functions, for example to add EventHandlers firing when something changed in the view, for example language or culture setting changes from another window. With the EventToCommandBehavior binding, we would like to pass the fired custom event to our view model to execute an async command. Although the event is not shown for autocompletion, everything works fine during runtime, and the command is executed when the event was fired. Unfortunately, the VisualStudio XAML designer cannot bind the custom event handler for the EventToCommand Behavior tag and therefore shows an exception within the XAML code, and within the XAML designer. Because of that binding problem, we are unable to further use the designer to get a preview of our designed windows.

We tried to derive our window from the basic WPF window (System.Windows.Window) and simply add the custom event handler but it did not work, either. Is there any problem with our implementation, or with the EventToCommandBehavior leading to an exception during design time? I have attached a minimal working example. In the code, I have derived a customized window class from the basic WPF window (shows the same error as the RadRibbonWindow), and have added a new event handler. This window is used as main window and fires the custom event when the event OnContentRendered function is called. The view binds this event within XAML to a command of the view model. The command is implemented with our customized asynchronous command. The XAML designer throws the described exception (as shown in the provided picture) but when I debug the program, a break point set within the function called by the command is hit.

I have removed the package "Telerik.Windows.Controls.for.Wpf.Xaml.2021.3.1109" within the .zip-folder because the code would have exceeded the maximum file size.

Sincerely,

Matthias Jörg

We are using RadRichText box along with HtmlDataProvider to create new para in specific notes- comments. As our application heavily relay on adding comments in html format when adding/ forwarding application to another user.

As a main control RadRichText box is working fine and dev team is recommending to use it in Production. But issue happens when we are rendering all comments as list associated to one application. Currently we have some application having more than 200 comments.

We used RadRichtext box to render HTML as readonly. but I impacted performance. Page take enough time to load contents. 

Currently we replaced RadRichText box with HtmlRenderer.WPF (HtmlPanel) control, which is much efficient compare to Telerik control. However HtmlPanel has its own limitation.

I wish if Telerik has such lightweight control to render HTML content in more efficient way, which does not effect application performance.

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%)

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.

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.
