Examples

In the following example, a RangeValuePattern object obtained from a target control is passed into a function that retrieves the current RangeValuePattern property values.

///--------------------------------------------------------------------
private object GetRangeValueProperty(
 RangeValuePattern rangeValuePattern,
 AutomationProperty automationProperty)
{
 if (rangeValuePattern == null || automationProperty == null)
 {
 throw new ArgumentException("Argument cannot be null.");
 }
