If you place a TextBlock in the QuickAccessToolbar and the Ofice_Black theme is applied you get black foreground on black background which makes the text unreadable. The content of the QAT must respect the theme applied to the RadRibbonView control.

When you hit the Enter key and a number simultaneously the number is removed from the Value of the RadMaskedNumericInput

Workaround:
Handle the KeyDown event of the RadMaskedNumericInput control, when the Enter key is pressed.

private void INPUT_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Key == Key.Enter)
    {
        if (INPUT.Value.ToString().Length > 0)
        {
            RadWindow.Alert(INPUT.Value.ToString());
        }
        e.Handled = true;
    }
}

<telerik:RadDiagram x:Name="diagram">
            <telerik:RadDiagramTextShape Content="Test" />
            <primitives:ItemInformationAdorner.AdditionalContent>
