Telerik UI for Windows Phone by Progress

The RadNumericUpDown control can also work in a read only mode. In this way the user will not be able to change the value in it. To bring it into a read only mode set the IsReadOnly property to True.

Here is an example.

<telerikInput:RadNumericUpDown x:Name="radNumericUpDown" VerticalAlignment="Center" IsReadOnly="True" />
