Hello Gary Blakely,
Thank you for writing.
You need to set the x:Name property of the GaugeRange you need to modify in your XAML file. By setting this property, the Silverlight design-time environment will automatically generate an internal field that you can use in your C# code.
For example if you have a XAML file that defines a gauge range like this:
You can refer to this radial range directly like so:
.radialRange.MaxValue = someValue;
The important thing is that this.radialRange
will be created inside
the InitializeComponent() method. Before this method it will be null.
Please write again if you need further assistance.
