treeview 下一节点

Question

级数不一定,如何从当前节点转到下一个叶节点

Answer 1

treeView.SelectedNode = e.TreeNode.NextNode

Answer 2

汗, 写错了treeView.SelectedNode = treeView.SelectedNode.NextNode

Answer 3

入图

就是如何从1.1到1.2.1

Answer 4

TreeNode next_node = treeView.SelectedNode.NextNode;
while (next_node.Nodes.Count > 0) {
    next_node = next.Nodes[0];
}
treeView.SelectedNode = next_node;

Answer 5

楼上的代码肯定不行!
级数不一定的,treeView.SelectedNode.NextNode到了一个项的最后一个页节点就返回空了

Answer 6

        private void button1_Click(object sender, EventArgs e)
        {
            //选中节点的下一个叶节点
            nextf(treeView1.SelectedNode);
        }
        //取下一个节点
        private void nextf(TreeNode treeNode)
        {
            int i = treeNode.Index;            //本身就是父节点
            if (treeNode.Nodes.Count > 0)
            {
                currentf(treeNode);
                return;
            }            //本身不是父节点但是根目录下的节点
            if (treeNode.Parent == null)
            {
                if (treeView1.Nodes.Count > i)
                {
                    currentf(treeView1.Nodes[i + 1]);
                    return;
                }
                else
                {
                    MessageBox.Show("不能往下了!");                }
            }
            else
            {
                if (treeNode.Parent.Nodes.Count > i + 1)
                {
                    //如果下一个结存在就取这个节点的叶节点
                    currentf(treeNode.Parent.Nodes[i + 1]);
                }
                else
                {
                    //如果没下个叶节点就求父节点的下一个节点的叶节点
                    if (treeNode.Parent.Parent == null)
                    {
                        if (treeView1.Nodes.Count > i)
                        {
                            currentf(treeView1.Nodes[i + 1]);
                            return;
                        }
                        else
                        {
                            MessageBox.Show("不能往下了!");                        }
                    }
                    else
                    {
                        currentf(treeView1.Nodes[treeNode.Parent.Index + 1]);
                    }
                }
            }
        }        //取最深的叶节点
        private void currentf(TreeNode treeNode)
        {
            if (treeNode.Nodes.Count == 0)
            {
                MessageBox.Show(treeNode.Text);
                return;
            }
            else
            {
                currentf(treeNode.Nodes[0]);
            }
        }

Answer 7

            TreeNode t_Node = treeView1.SelectedNode;
            TreeNode tn = new TreeNode();
            if (t_Node.Parent != null)
               tn = t_Node.Parent.NextNode;
           if (tn.Nodes.Count > 0)
           {
               treeView1.SelectedNode = tn.Nodes[0];
           }

Answer 8

if(treeView.SelectedNode.NextNode!=null)
{
   treeView.SelectedNode.NextNode.Selected=true;
}
