  Name Description
Public fieldStatic member TextPathProperty Identifies the TextPath attached property.



Use this class to associate strings with ItemsControl items for search purposes. You can specify the property that identifies an item by setting the TextPath attached property. For example, if a ListBox contains a collection of Image objects, you can set the TextPath property to “Name”. Then if you set the Name value for one of the images to "dog", the user could select that image by typing “dog” in the ListBox. When the user types enough of the word to distinguish it from other items in the collection, the dog item is selected and displays in the ListBox.


The typed text may not display in the ItemsControl unless the list contains strings or the ItemsControl has a data template associated with it that displays the identifying strings.

In addition to using the TextPath property, the system will try to obtain a string for search purposes in the following order:

The search is always case-insensitive.
