winfrom treeview的綁定

 private void CreateTree(TreeNodeCollection tns, int ParentId, List<StorageGrid> iL)
        {
            List<StorageGrid> iLNodes = iL.Where(c => c.ParentId == ParentId).ToList();
            foreach (StorageGrid sg in iLNodes)
            {
                TreeNode tn = new TreeNode();
                tn.Text = sg.StorageGridName;
                tn.ToolTipText = sg.ID.ToString();
                tns.Add(tn);
                CreateTree(tn.Nodes, sg.ID, iL);
            }
        }

CreateTree(treeView1.Nodes, 0, StorageGridBLL.GetStorageList());

 

指定某個節點的焦點

private void CreateTree(TreeNodeCollection tns, int ParentId, List<StorageGrid> iL)
        {
            List<StorageGrid> iLNodes = iL.Where(c => c.ParentId == ParentId).ToList();
            foreach (StorageGrid sg in iLNodes)
            {
                TreeNode tn = new TreeNode();
                tn.Text = sg.StorageGridName;
                tn.ToolTipText = sg.ID.ToString();
                if (tn.ToolTipText == ID)
                {
                    treeView1.SelectedNode = tn;
                }
                tns.Add(tn);
                CreateTree(tn.Nodes, sg.ID, iL);
            }
        }
