c# - 无法在 ObjectViewList TreeView 中显示文本

Question

我正在使用 ObjectViewList TreeListView 并按照示例进行操作，但没有显示文本。TreeListView 确实填充了，您可以看到可以展开的节点，并且它们确实以正确数量的子节点展开，但文本不显示。

下面是代码：

private void SetupTree(TreeNode objectRoot)
    {

        
        this.treeObjectView.CanExpandGetter = delegate (object x) {
            return ((TreeNode)x).Nodes.Count > 0;
        };
       
        this.treeObjectView.ChildrenGetter = delegate (object x) {
            try
            {
                return ((TreeNode)x).Nodes;
            }
            catch (UnauthorizedAccessException ex)
            {
                this.BeginInvoke((MethodInvoker)delegate () {
                    this.treeObjectView.Collapse(x);
                    MessageBox.Show(this, ex.Message, "ObjectListViewDemo", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
                });
                return new ArrayList();
            }
        };
        
        ArrayList roots = new ArrayList();
        
        foreach (TreeNode di in objectRoot.Nodes)
        {
             roots.Add(di);                
        }           

        this.treeObjectView.Roots = roots;        
    }

这是设计器代码：

    {

        // 
        // treeObjectView
        // 
        this.treeObjectView.AllColumns.Add(this.objectName);
        this.treeObjectView.CellEditUseWholeCell = false;
        this.treeObjectView.Columns.AddRange(new System.Windows.Forms.ColumnHeader[] {
        this.objectName});
        this.treeObjectView.Dock = System.Windows.Forms.DockStyle.Fill;
        this.treeObjectView.HideSelection = false;
        this.treeObjectView.Location = new System.Drawing.Point(3, 3);
        this.treeObjectView.Name = "treeObjectView";
        this.treeObjectView.ShowGroups = false;
        this.treeObjectView.Size = new System.Drawing.Size(533, 589);
        this.treeObjectView.TabIndex = 3;
        this.treeObjectView.UseCompatibleStateImageBehavior = false;
        this.treeObjectView.View = System.Windows.Forms.View.Details;
        this.treeObjectView.VirtualMode = true;
        // 
        // objectName
        // 
        this.objectName.MinimumWidth = 200;
        this.objectName.Text = "Text";
        this.objectName.ToolTipText = "Object Name";
        this.objectName.Width = 200;
     }

关于我做错了什么的任何想法？

这实际上是脑死愚蠢的简单，我没有密切注意演示。您所要做的就是设置要显示的属性。

 this.objectName.AspectName = "Text";
