TextSearch.TextPath Attached Property
Gets or sets the name of the items' property that identifies each item in a control's collection.
Assembly: PresentationFramework (in PresentationFramework.dll)
Use this property on a control that contains a collection of items. The value of the specified property is the text that the user can type to select the item, and the text that is displayed if the control is set to display text in its TextBox. If you set the Text property on a control's collection item, the property will be ignored. If you set the property to a value that is not the name of an actual property, is ignored.
