Ejemplos

El siguiente ejemplo de código establece la PathSeparator propiedad de un TreeView y muestra el número de nodos secundarios que se encuentra en la TreeNodeCollection de la 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 de nodos secundarios a los nodos de árbol total 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. En este ejemplo requiere que haya un Form con un Buttony un TreeView controlar con un TreeNodeCollection que tiene varios TreeNode objetos (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." ) );

Comentarios

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