RadSyntaxEditor, while inside of a virtualized RadGridView, stealings focus immediately upon loading. It appears to do this automatically and there is no configuration to disabling. Meaning when scrolling in a RadGridView with virtualized rows, when a row with the RadSyntaxEditor materializes it will automatically steal focus from other elements.

This can be worked around using custom behavior that discards the first preview keyboard focus event that it receives.

private void onPreviewGotKeyboardFocus(object s, KeyboardFocusChangedEventArgs e)
{
    if (!this.SuppressAutoFocus || _wasFocusSuppressed)
    {
        return;
    }

    _wasFocusSuppressed = true;
    e.Handled = true;
}

The offending line of code is this in RadSyntaxEditor.InitActiveEditorPresenter:

if (flag)
{
    base.Dispatcher.BeginInvoke((Action)delegate
    {
        Focus();
    });
}

Request: Add a dependency property to allow opting-out of this default behavior. The above workaround works, but is a bit hacky for something that should probably be built-in.

In this case, the Move() method of the bound collection (ObservableCollection in this case) is used. The internal QueryableCollectionView correctly tracks the moved item's new position, but CollectionEditor.CurrentIndex remains at the old index, causing the visual selection highlight to point to the wrong item.

In RadGanttView, the drag reorder visual element position indicators ('Before', 'After', and 'Inside') are not translated according to the application's UI culture settings (e.g., German), remaining displayed in English because they are hardcoded in the element's template.

To work this around, create a custom DragReorderTemplate and apply it via the CueTemplateSelector of GanttDragResizeVisualCue. This can be applied via an implicit style defined in App.xaml.

 <Style TargetType="telerik:GanttDragResizeVisualCue">
     <Setter Property="CueTemplateSelector">
         <Setter.Value>
             <telerik:GanttDragVisualCueContentTemplateSelector DragTemplate="{StaticResource GanttDragResizeVisualCueTemplate}"
                                                         ResizeTemplate="{StaticResource GanttDragResizeVisualCueTemplate}"
                                                         CreateDependencyTemplate="{StaticResource GanttCreateDependencyTemplate}"
                                                         DragReorderTemplate="{StaticResource CustomGanttDragReorderTemplate}" />
         </Setter.Value>
     </Setter>
 </Style>

The bug happens when we have two or more rows merged in the first column and programmatically, we make the rowDetails for the first row visible, the merged cells of the first column stay merged and are over of the rowDetails, hiding a part of the Row Details:

Steps to reproduce:

1. Open Word 2016 or later. Create a new blank document. Type any text. **File → Save As** → `original.docx`.
2. Verify mode 15: rename `original.docx` to `.zip`, open `word/settings.xml`, confirm `<w:compatSetting w:name="compatibilityMode" ... w:val="15"/>`. Rename back to `.docx`.
3. Open Telerik's WPF Demos sample in Microsoft Store (RichTextBox demo). Open `original.docx`.
4. Without making any edit, click **Save** (or File → Save As) → `roundtrip.docx`.
5. Rename `roundtrip.docx` to `.zip` and open `word/settings.xml`. The value is now `<w:compatSetting w:name="compatibilityMode" ... w:val="14"/>`.

Currently, the SdtProperties classes (ex: DateProperties) can be extended by overriding the GetBuilder() method. This allows you to implement custom ISdtBuilder that creates the document content of the SDT form. However, the custom properties are not taken into account during import/export. Consider adding some kind of custom information about the custom SdtProperties type during export and restore it during import. Or at the least provide API (like an event or method override) that can intercept the creation of the SdtProperties during import which will allow you to replace the default SdtProperties object.

Currently, the userDataFolder given to the CoreWebView2Environment object used with the WebView2 speech recognizer is hardcoded to a specific folder. 

Add an option to allow the developer to set the userDataFolder manually in the default WebView2SpeechRecognizer. Or at the least to respect the WEBVIEW2_USER_DATA_FOLDER environment variable which is used when the userDataFolder parameter is not used.
