예제

다음 코드 예제에서는 PathSeparator 의 속성을 TreeView 에 포함 된 자식 트리 노드의 수를 표시 하 고는 TreeNodeCollectionSelectedNode합니다.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. 트리 뷰 컨트롤의 전체 트리 노드에 자식 트리 노드의 백분율도 표시 됩니다.The percentage of child tree node to total tree nodes in the tree view control is also displayed. 이 예제를 실행 하려면를 Form 사용 하 여는 Button, 및 TreeView 컨트롤을 TreeNodeCollection 가 몇 개 TreeNode 개체 (가령, 3 개 이상의 수준).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)
{
   // 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("The '" + myTreeView.SelectedNode.FullPath + "' node has "
     + myNodeCount.ToString() + " child nodes.\nThat is "
     + string.Format("{0:###.##}", myChildPercentage)
     + "% of the total tree nodes in the tree view control.");
}

   Dim myChildPercentage As Decimal = CDec(myNodeCount) / _
      CDec(myTreeView.GetNodeCount(True)) * 100

설명

없으면 TreeNode 현재 선택 된 SelectedNode 속성이 null.If no TreeNode is currently selected, the SelectedNode property is null.

이 속성을 설정 하는 경우 지정된 된 노드 보기 및 모든 부모 노드가 지정된 된 노드를 볼 수 있도록 확장 되어 스크롤됩니다.When you set this property, the specified node is scrolled into view and any parent nodes are expanded so that the specified node is visible.

부모 노드 또는 선택한 노드의 모든 상위 노드를 축소 하거나 프로그래밍 방식으로, 사용자 동작을 통해 선택한 노드가 축소 된 노드에 됩니다.When the parent node or any ancestor node of the selected node is collapsed either programmatically or through user action, the collapsed node becomes the selected node.
