Classes that Derive from the WPFItemsControl Class

Silk Test Workbench can interact with classes that derive from WPFItemsControl, such as WPFListBox, WPFTreeView, and WPFMenu, in two ways:

Working with the control

Most controls contain methods and properties for typical use cases. The items are identified by text or index.
For example:
```
listBox.Select("Banana")
listBox.Select(2)

tree.Expand("/Fruit/Banana")
```
Working with individual items, such as WPFListBoxItem, WPFTreeViewItem, or WPFMenuItem

For advanced use cases, use individual items. For example, use individual items for opening the context menu on a specific item in a list box, or clicking a certain position relative to an item.
For example:
```
Dim item as WPFListBoxItem = listBox.WPFListBoxItem("banana")
item.OpenContextMenu()
```
