Following paste is one of my updowns. it works fine except when I'm in full screen mode. When in full screen, the up and down buttons will change the value but you cant enter the field and enter a value. It has not effect and the ValueChanged event does not get triggered when trying to enter the filed or losing focus. (using sl4 q2 2010 controls)
<telerikInput:RadNumericUpDown Minimum="0" Margin="1" ValueFormat="Numeric" x:Name="h1ud" ValueChanged="h1ud_ValueChanged" Width="auto" Height="auto" Grid.Row="2" Grid.Column="1"/>
