Exemplos

O exemplo de código a seguir seleciona o apropriado TreeNode depois de determinar se a TreeNode entrada passada está selecionada e qual TreeNode selecionar. Este exemplo requer que você tenha um Form controle com TreeView um TreeNodeCollection que contenha vários TreeNode objetos. Ele também requer que você tenha um ComboBox com os seguintes itens: "Anterior", "PreviousVisible", "Next", "NextVisible", "First" e "Last".

void SelectNode( TreeNode^ node )
{
   if ( node->IsSelected )
   {
      
      // Determine which TreeNode to select.
      String^ str = myComboBox->Text;
      if ( str->Equals( "Previous" ) )
               node->TreeView->SelectedNode = node->PrevNode;
      else
      if ( str->Equals( "PreviousVisible" ) )
               node->TreeView->SelectedNode = node->PrevVisibleNode;
      else
      if ( str->Equals( "Next" ) )
               node->TreeView->SelectedNode = node->NextNode;
      else
      if ( str->Equals( "NextVisible" ) )
               node->TreeView->SelectedNode = node->NextVisibleNode;
      else
      if ( str->Equals( "First" ) )
               node->TreeView->SelectedNode = node->FirstNode;
      else
      if ( str->Equals( "Last" ) )
               node->TreeView->SelectedNode = node->LastNode;
   }

   node->TreeView->Focus();
}

private void SelectNode(TreeNode node)
{
    if(node.IsSelected)
    {
        // Determine which TreeNode to select.
        switch(myComboBox.Text)

        }
    }
