Definición

Obtiene o establece un valor que indica si el resalte de la selección abarca todo el ancho del control de vista de árbol.Gets or sets a value indicating whether the selection highlight spans the width of the tree view control.

public:
 property bool FullRowSelect { bool get(); void set(bool value); };
public bool FullRowSelect { get; set; }
member this.FullRowSelect : bool with get, set
Public Property FullRowSelect As Boolean

Ejemplos

En el ejemplo de código siguiente se muestra TreeViewun personalizado.The following code example illustrates a customized TreeView. Al heredar la TreeView clase, esta versión personalizada tiene toda la funcionalidad de un típico TreeView.By inheriting the TreeView class, this custom version has all the functionality of a typical TreeView. Cambiar varios valores de propiedad en el constructor proporciona una apariencia única.Changing various property values in the constructor provides a unique appearance. Dado que ShowPlusMinus la propiedad está establecida falseen, el control personalizado también invalida el OnAfterSelect método para que los nodos puedan expandirse y contraerse cuando se haga clic en ellos.Because the ShowPlusMinus property is set to false, the customized control also overrides the OnAfterSelect method so nodes can be expanded and collapsed when they are clicked.

Un control personalizado de esta manera se puede usar en toda la organización, lo que facilita proporcionar una interfaz coherente sin requerir que se especifiquen las propiedades del control en cada proyecto individual.A control that is customized in this way can be used throughout an organization, making it easy to provide a consistent interface without requiring the control properties to be specified in each individual project.

Comentarios

Cuando FullRowSelect estrue, un resaltado de la selección abarca todo el ancho de la vista de árbol, en lugar del ancho de la etiqueta del nodo de árbol.When FullRowSelect is true, a selection highlight spans the entire width of the tree view, display instead of the width of just the tree node label. La FullRowSelect propiedad se omite si ShowLines está establecido en true.The FullRowSelect property is ignored if ShowLines is set to true.
