Definición

Obtiene o establece la cadena de delimitación que utiliza la ruta de acceso del nodo de árbol.Gets or sets the delimiter string that the tree node path uses.

public:
 property System::String ^ PathSeparator { System::String ^ get(); void set(System::String ^ value); };
public string PathSeparator { get; set; }
member this.PathSeparator : string with get, set
Public Property PathSeparator As String

Ejemplos

En el ejemplo de código siguiente se establece la propiedad PathSeparator de un TreeView y se muestra el número de nodos de árbol secundarios contenidos en el @no__t 2 del SelectedNode.The following code example sets the PathSeparator property of a TreeView and displays the number of child tree nodes that is contained in the TreeNodeCollection of the SelectedNode. También se muestra el porcentaje del nodo de árbol secundario para el total de nodos de árbol en el control de vista de árbol.The percentage of child tree node to total tree nodes in the tree view control is also displayed. Este ejemplo requiere que tenga un Form con un Button y un control @no__t 2 con un TreeNodeCollection que tenga varios objetos TreeNode (preferiblemente con tres o más niveles).This example requires that you have a Form with a Button, and a TreeView control with a TreeNodeCollection that has several TreeNode objects (preferably with three or more levels).

void myButton_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
{

   // Set the tree view's PathSeparator property.
   myTreeView->PathSeparator = ".";

   // Get the count of the child tree nodes contained in the SelectedNode.
   int myNodeCount = myTreeView->SelectedNode->GetNodeCount( true );
   Decimal myChildPercentage = ((Decimal)myNodeCount / (Decimal)myTreeView->GetNodeCount( true )) * 100;

   // Display the tree node path and the number of child nodes it and the tree view have.
   MessageBox::Show( String::Concat( "The '", myTreeView->SelectedNode->FullPath, "' node has ", myNodeCount, " child nodes.\nThat is ", String::Format( "{0:###.##}", myChildPercentage ), "% of the total tree nodes in the tree view control." ) );
}
private void myButton_Click(object sender, System.EventArgs e)

   decimal myChildPercentage = ((decimal)myNodeCount/
     (decimal)myTreeView.GetNodeCount(true)) * 100;

   // Display the tree node path and the number of child nodes it and the tree view have.
   MessageBox.Show("The '" + myTreeView.SelectedNode.FullPath + "' node has "
     + myNodeCount.ToString() + " child nodes.\nThat is "
     + string.Format("{0:###.##}", myChildPercentage)

      CDec(myTreeView.GetNodeCount(True)) * 100

   ' Display the tree node path and the number of child nodes it and the tree view have.

Comentarios

La ruta de acceso del nodo de árbol consta de un conjunto de etiquetas de nodo de árbol separadas por las cadenas de delimitador PathSeparator.The tree node path consists of a set of tree node labels separated by the PathSeparator delimiter strings. Las etiquetas van desde el nodo de árbol raíz hasta el nodo de árbol que desee.The labels range from the root tree node to the tree node that you want.
