public struct GeneratorPosition
<GeneratorPosition .../>

GeneratorPosition is used by StartAt.

The following example illustrates how to use GeneratorPosition to start generating forward from the beginning of an item list.

// Start generating items forward from the beginning of the item list
GeneratorPosition position = new GeneratorPosition(-1, 0);
GeneratorDirection direction = GeneratorDirection.Forward;
IItemContainerGenerator generator = (IItemContainerGenerator)this.itemsControl.ItemContainerGenerator;
generator.StartAt(position, direction);

The following example illustrates how to use GeneratorPosition to start generating backward from the end of an item list.

// Start generating items backward from the end of the item list
GeneratorPosition position = new GeneratorPosition(-1, 0);
GeneratorDirection direction = GeneratorDirection.Backward;
IItemContainerGenerator generator = (IItemContainerGenerator)this.itemsControl.ItemContainerGenerator;
generator.StartAt(position, direction);

The following example illustrates how to use GeneratorPosition to start generating forward from the middle of an item list.

// Start generating items forward, 
// starting with the first unrealized item (offset of 1), 
// after the 5th realized item 
// (the item with index 4 among all realized items) in the list
GeneratorPosition position = new GeneratorPosition(4, 1);
GeneratorDirection direction = GeneratorDirection.Forward;
IItemContainerGenerator generator = (IItemContainerGenerator)this.itemsControl.ItemContainerGenerator;
generator.StartAt(position, direction);
