Empty cells appear when the RadGridView contains many cells in the viewport and the view gets resized.

To work this around you can extract and modify the ControlTemplate of GridViewCell, in order to set the MinHeight property of the "PART_ContentPresenter" element to a number close to the RowHeight of the RadGridView control.

InvalidOperationException when closing a RadWindow opened on a separated UI thread. The exception message is: "Cannot use a DependencyObject that belongs to a different thread than its parent Freezable."

To work this around, you can merge the Telerik.Windows.Controls.Navigation.xaml dictionary in the Resources of all RadWindow instances open on another thread and then set their Style property to the RadWindowStyle from the merged .xaml dictionary.

The fly view is not properly displayed when the second item is clicked and the sub-items are expanded (see attached video). 

Attached is a project with a workaround as well. 

Enable the customers to create and modify .pptx (PowerPoint) files . They need processing as well as showing such documents.

When you inherit BingRestMapProvider and BingRestTileMapSource, following the custom map provider approach
https://docs.telerik.com/devtools/wpf/controls/radmap/how-to/howto-custom-provider

the map does not display any tiles. This is due to internal property TopLayer not set correctly to the TileMapSource class.

Hi

I would like to know if Progress Telerik has some plan to port their WPF controls to Avalonia (avaloniaui.net).

Thanks

Make the following selection-related methods of the HeatMapDefinition class "protected internal virtual" instead of "internal virtual". 

• IsCellSelected
  
• IsRowSelected
  
• IsColumnSelected
  

This will allow the developer to properly implement also the selection feature in their custom heat map definition code.

HtmlFormatProvider: Exception when importing a table that has only width set.  In this case, we are trying to measure some elements with float.NaN. 

Workaround: Use the HtmlFormatProvider from the Document Processing library. 

In the Office2019 theme, the RadGridView's ScrollBar elements should have transparent background by design. This is the track's background shown behind the thumb element that allows drag-to-scroll. Currently, the ScrollBars have a gray background.

To work this around, you can define an implicit Style in the App.xaml that targets the GridViewScrollViewer control. Then, set its Background property.

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Office2019;component/Themes/System.Windows.xaml"/>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Office2019;component/Themes/Telerik.Windows.Controls.xaml"/>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Office2019;component/Themes/Telerik.Windows.Controls.Input.xaml"/>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Office2019;component/Themes/Telerik.Windows.Controls.GridView.xaml"/>
        </ResourceDictionary.MergedDictionaries>
        <Style TargetType="telerik:GridViewScrollViewer" BasedOn="{StaticResource GridViewScrollViewerStyle}">
            <Setter Property="Background" Value="Transparent"/>
        </Style>
    </ResourceDictionary>
</Application.Resources>

When i set the Urisource through a binding and not directly through the xaml the svg image is not shown in combination with paint servers.

I had a look at the code and the issue is that the paint server gets not set again (see attachment)
