        HorizontalAlignment="Center"
        DropDownOpening="RadDropDownButton_DropDownOpening"
        Content="...">
        <telerik:RadDropDownButton.DropDownContent>
            <TextBlock Text="Sample content" />
        </telerik:RadDropDownButton.DropDownContent>
    </telerik:RadDropDownButton>

    private void RadDropDownButton_DropDownOpening( object sender, RoutedEventArgs e )
    {
        e.Handled = true;
    }

    Hi Ivan,

    Thank you for reporting this issue. I was able to reproduce the described behavior on our side and we can confirm this is a bug. Therefore I logged it in our Feedback portal where you can track its progress. I have also updated your Telerik points as a small appreciation for your cooperation.

    In the meantime, as a workaround you can use PreviewMouseLeftButtonDown event of the DropDownButton instead of DropDownOpening  event.

    Please excuse us for any inconvenience caused.

    Regards,
