This class is used to assign a string to items in a control's collection. Assigning a string to each item in the collection accomplishes two objectives. It specifies the text to display when the item is selected, and it enables the user to select an item by typing the assigned string.
For example, assume that a ComboBox contains a collection of Image objects, one of which is an image of a dog. If you assign the string, "Dog" to that item, the user can select the dog by typing the word in the combo box's text box. As soon as the user types enough of the word to distinguish it from other items in the selection, the image of the dog will be selected. If IsEditable is set to true on the ComboBox, "Dog" will appear in the text box.
You can specify the text that identifies an item by using the TextSearch::TextPath property on a control or by setting the Text property on each item in the control's collection. Setting one of these properties ensures that unexpected text is not displayed. If you set the Text property on a control's collection item, the TextPath property will be ignored. If you set the TextPath property to a value that is not the name of an actual property, TextPath is ignored.
You cannot declare this managed class in XAML, but you can use its static properties to assign values in XAML.
The following examples create ComboBox controls that contain images as items instead of text. Functionally, the examples are the same. The first example sets the TextPath property on the ComboBox and the second example sets the Text property on each item in the collection.
<ComboBox IsEditable="true" TextSearch.TextPath="Name"> <Image Name="Cat" Source="data\cat.png"/> <Image Name="Dog" Source="data\dog.png"/> <Image Name="Fish" Source="data\fish.png"/> </ComboBox>
