public static AggregationView<TSource,TResult> LiveMax<TSource,TResult>( 
   View<TSource> source,
   System.Linq.Expressions.Expression<Func<TSource,TResult>> selector
)

Parameters

source

A view containing the values to determine the maximum value of.

selector

A transform function to apply to each element.

Type Parameters

TSource

The type of the elements of source.

TResult

The type of the value returned by selector.

Return Value

If type TResult implements System.IComparable`1, this method uses that implementation to compare values. Otherwise, if type TResult implements System.IComparable, that implementation is used to compare values.

It is possible to use standard LINQ query operator Max instead of LiveMax. Both are "live" in the sense that they are recomputed automatically when any change occurs in the source. The difference is that Max will every time loop through the entire source collection and aggregate it from scratch, whereas LiveMax will use a more performant algorithm, will maintain its value incrementally, processing only those source items that actually changed.
