TreeView.NodeIndent TreeView.NodeIndent TreeView.NodeIndent TreeView.NodeIndent Property

Definizione

Ottiene o imposta il numero di rientro (in pixel) per i nodi figlio del controllo TreeView.Gets or sets the indentation amount (in pixels) for the child nodes of the TreeView control.

public:
 property int NodeIndent { int get(); void set(int value); };
public int NodeIndent { get; set; }
member this.NodeIndent : int with get, set
Public Property NodeIndent As Integer

Valore della proprietà

Spazio (in pixel) tra il bordo sinistro del nodo figlio e il bordo sinistro del relativo nodo padre.The amount of space (in pixels) between a child node's left edge and its parent node's left edge. Il valore predefinito è 20.The default is 20.

Esempi

Nell'esempio di codice riportato di seguito viene illustrato NodeIndent come utilizzare la proprietà per controllare il rientro dei nodi figlio.The following code example demonstrates how to use the NodeIndent property to control the indentation of child nodes.

Commenti

Utilizzare la NodeIndent proprietà per controllare la quantità di spaziatura tra il bordo sinistro di un nodo figlio e il bordo sinistro del nodo padre.Use the NodeIndent property to control the amount of spacing between the left edge of a child node and the left edge of its parent node.

Nota

La NodeIndent proprietà ha effetto TreeView su ogni nodo figlio nel controllo.The NodeIndent property affects every child node in the TreeView control. Non è possibile controllare la quantità di rientri di ogni nodo singolarmente.It is not possible to control the indentation amount of each node individually.

Il valore di questa proprietà viene archiviato nello stato di visualizzazione.The value of this property is stored in view state.
