I have a WPF window containing a RadWebCam control and a CameraSettingsControl control associated with it (as shown in the online documentation). When I close the WPF window, no memory associated with that window is released. I implemented a Finalizer in the window and found that it wasn't getting called even after several GC.Collect() calls.  The culprit appears to be the CameraSettingsControl when it's associated with the RadWebCam control. In my application, it's not freeing about 80MB of memory after each window invocation.

I have included a full project sample which demonstrates the issue. Just set a BreakPoint on the finalizer ~TakePicture(). When the application is run, hit the 'Take Picture' button to launch the Camera window, and then close it.  To verify that it's not just a delay in garbage collection, hit the GCCollect button on the main window a couple of times. The Finalizer never gets called until you exit the app.

Here's the Telerik control WPF I'm using, but it's also in the sample.

<telerikWebCam:RadWebCam Grid.Column ="0" x:Uid="WebCamCaptureWindow_RadWebCam" x:Name="webCam" MinWidth="0" MinHeight="0" AutoStart="False" Margin="0 25 0, 0" 

When using Windows 11 theme with 4.5 NoXaml binaries, AutoCompleteBox reports a XAML Binding Failure:

To reproduce, just run the following window (just an empty AutoCompleteBox) in a new WPF Framework project:

<Window x:Class="WpfApp20.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfApp20" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Windows11;component/Themes/System.Windows.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Windows11;component/Themes/Telerik.Windows.Controls.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Windows11;component/Themes/Telerik.Windows.Controls.Input.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>
    <Grid>
        <telerik:RadAutoCompleteBox/>
    </Grid>
</Window>

Working with PasteOptionsPopup may cause an exception in LayoutElement.SetParent. Very difficult to reproduce, having no consistent steps. Maybe it is related to undo of paste command, but there are no other clues aside from this.

I've encountered a tiny bug when it comes to styling AutoCompleteBox using StyleManager.
If I set the StyleManager.ApplicationTheme of my app, the styling is correct, see the reference gif:

But if I set the style of AutoCompleteBox during runtime with StyleManager.SetTheme, the styling is not quite right - the underlying RadWatermarkBox is using the basic style I believe, because the text doesn't change it opacity when I hover over it (in the case of watermark text) or when I defocus the element (in the case of real text).

The example I'm using is just an empty WPF project with MainWindow.xaml having one RadAutoCompleteBox inside it, and MainWindow.xaml.cs is pictured in the gifs.

Hi

I have a grid where some rows contain child rows.  In order to control which rows have the "+" expander icon I use the IsExpandableBinding property.  I also have a toolbar which contains a convenience button to collapse all the expanded rows.

This button is bound to a handler which called RasGridView.CollapseAllHierarchyItems(), but this does not have any effect.  I've tried removing the IsExpandableBinding property, and the collapse mechanism then works (but I get unwanted expanders on every row).

When importing a XAML document that contains a Content control with PrefixMappings to its TextProperties` DataBinding an exception is thrown: 'Telerik.Windows.Documents.Model.StructuredDocumentTags.DataBinding.PrefixMappings' threw an exception.'

Currently, the range of the ScaleFactor property is between 0.1 and 4.0. We could include API to allow the user to set minimum and maximum boundaries that are between the default range (0.1 and 4.0).

For example:

• MinimumScaleFactor=0.8 
• MaximumScaleFactor = 1.5
