when setting Telerik PlatformDark and PlatformLight themes, the DataPager_PageSizesView_LabelText  localization string of the DataPager does not apply. 

Workaround: Use the Telerik themes

When setting horizontal text alignment to center, the text in Telerik Entry is not centered. In MAUI entry works.

Delegate aggregate descriptor does not update value in the UI when adding/removing item.

The behavior also happens with the property aggregate descriptor.

1. Unexpected indent at the right, Android/iOS.
2. iOS only issue - width of CollectionView content continuously changes during scroll - to fill that ident and back.

When setting GroupAggregatesAlignment NextToHeader and the column size mode is stretch or auto, the aggregates text in the group header is misaligned, part of the text enters in next column when data changes.

when the column is resized or datagrid is scrolled, the aggregates are aligned as expected

Null reference exception occurs when measuring the cells container:

Description:

On iOS and MacCatalyst, when a RadButton is placed inside a RadToggleButton's ContentTemplate and bound to a command, the command does not execute when the nested button is tapped. The same setup works as expected on Windows and Android.

Workaround:

Override the toggle button's handler to adjust gesture recognizer behavior so that touches on the nested UIButton are not intercepted by the parent RadToggleButton.

private void Element_OnHandlerChanged(object? sender, EventArgs e)
    {
#if IOS || MACCATALYST
        var button = sender as RadToggleButton;
        var handler = button!.Handler;
        if (handler != null && handler.PlatformView is UIKit.UIView platformView)
        {
            this.Dispatcher.Dispatch(() =>
            {
                var recognizer = platformView.GestureRecognizers!.Last();
                recognizer.ShouldReceiveTouch = (gestureRecognizer, touch) =>
                {
                    var view = touch.View;
                    if (view is UIButton)
                    {
                        return false;
                    }

                    return true;
                };
            });
        }
#endif
    }
