C# 如何使用winforms在多列模式下向TreeViewAdv添加项

我在玩一个叫做的控件。我已经添加了控件，并添加了几列，试图了解它是如何工作的。但直到现在，当我向控件添加项时，我得到的只是空节点。控件提供的示例一点也不清楚，当我试图弄清楚数据是如何添加到控件中时，它只是让我头疼。无论如何，这就是我到目前为止所做的，我希望有人能引导我走向正确的方向

    TreeModel _model = new TreeModel();
    treeViewAdv1.Model = _model;

    treeViewAdv1.BeginUpdate();
    for (int i = 0; i < 20; i++)
    {

        Node parentNode = new Node("root" + i);
        _model.Nodes.Add(parentNode);

        for (int n = 0; n < 2; n++)
        {
            Node childNode = new MyNode("child" + n);
            parentNode.Nodes.Add(childNode); 
        }

    }

    treeViewAdv1.EndUpdate();

TreeModel\u model=newtreemodel（）；
treeViewAdv1.Model=\u Model；
treeViewAdv1.BeginUpdate（）；
对于（int i=0；i<20；i++）
{
节点parentNode=新节点（“根”+i）；
_model.Nodes.Add（parentNode）；
对于（int n=0；n<2；n++）
{
Node childNode=新的MyNode（“子节点”+n）；
parentNode.Nodes.Add（childNode）；
}
}
treeViewAdv1.EndUpdate（）；

总之，我得到的只是空节点，我真的不知道如何向其他列添加数据。。。任何帮助都将不胜感激……

您需要先实例化您的列，然后将它们附加到树视图。毕竟，在同一单元格索引的所有列中添加新单元格。

希望能够提供帮助，以防您仍在为这个问题而挣扎，或者其他人也遇到同样的问题：空节点的解决方案是为树指定一个视图组件

TreeViewAdv使用MVC，它要求您指定一个视图，尽管这在示例项目中并不明显。TreeViewAdv源中nodeControl文件夹下的NodeTextBox类是您可以使用的查看器之一。您需要将其添加到表单中，并通过其DataPropertyName属性将其连接到树控件，如下所示：

this._tBox.DataPropertyName = "Text";

private Aga.Controls.Tree.TreeViewAdv _treeViewAdv;
private Aga.Controls.Tree.TreeColumn Column1;
private Aga.Controls.Tree.TreeColumn Column2;
private Aga.Controls.Tree.TreeColumn Column3;
private Aga.Controls.Tree.NodeControls.NodeTextBox NodeControl1;
private Aga.Controls.Tree.NodeControls.NodeTextBox NodeControl2;
private Aga.Controls.Tree.NodeControls.NodeTextBox NodeControl3;

private InitializeComponent()
{     
    // Left out all other initialization, since this was long enough already.
    this.treeViewAdvPrint = new Aga.Controls.Tree.TreeViewAdv();
    this.Column1 = new Aga.Controls.Tree.TreeColumn();
    this.Column2 = new Aga.Controls.Tree.TreeColumn();
    this.Column3 = new Aga.Controls.Tree.TreeColumn();
    this.NodeControl1 = new Aga.Controls.Tree.NodeControls.NodeTextBox();
    this.NodeControl2 = new Aga.Controls.Tree.NodeControls.NodeTextBox();
    this.NodeControl3= new Aga.Controls.Tree.NodeControls.NodeTextBox();

    // 
    // _treeViewAdv
    // 
    this._treeViewAdv.BackColor = System.Drawing.SystemColors.Window;
    this._treeViewAdv.Columns.Add(this.Column1);
    this._treeViewAdv.Columns.Add(this.Column2);
    this._treeViewAdv.Columns.Add(this.Column3);
    this._treeViewAdv.DefaultToolTipProvider = null;
    this._treeViewAdv.DragDropMarkColor = System.Drawing.Color.Black;
    this._treeViewAdv.GridLineStyle = ((Aga.Controls.Tree.GridLineStyle)((Aga.Controls.Tree.GridLineStyle.Horizontal | Aga.Controls.Tree.GridLineStyle.Vertical)));
    this._treeViewAdv.LineColor = System.Drawing.SystemColors.ControlDark;
    this._treeViewAdv.Location = new System.Drawing.Point(12, 12);
    this._treeViewAdv.Model = null;
    this._treeViewAdv.Name = "_treeViewAdv";
    this._treeViewAdv.NodeControls.Add(NodeControl1);
    this._treeViewAdv.NodeControls.Add(NodeControl2);
    this._treeViewAdv.NodeControls.Add(NodeControl3);
    this._treeViewAdv.SelectedNode = null;
    this._treeViewAdv.Size = new System.Drawing.Size(443, 356);
    this._treeViewAdv.TabIndex = 6;
    this._treeViewAdv.Text = "_treeViewAdv";
    this._treeViewAdv.UseColumns = true;

    // 
    // Column1
    // 
    this.Column1.Header = "Column 1";
    this.Column1.SortOrder = System.Windows.Forms.SortOrder.None;
    this.Column1.TooltipText = null;
    this.Column1.Width = 290;
    // 
    // Column3
    // 
    this.Column3.Header = "Column 3";
    this.Column3.SortOrder = System.Windows.Forms.SortOrder.None;
    this.Column3.TextAlign = System.Windows.Forms.HorizontalAlignment.Center;
    this.Column3.TooltipText = null;
    // 
    // Column2
    // 
    this.Column2.Header = "Column 2";
    this.Column2.SortOrder = System.Windows.Forms.SortOrder.None;
    this.Column2.TextAlign = System.Windows.Forms.HorizontalAlignment.Center;
    this.Column2.TooltipText = null;
    this.Column2.Width = 91;
    // 
    // NodeControl1
    // 
    this.NodeControl1.DataPropertyName = "NodeControl1";
    this.NodeControl1.IncrementalSearchEnabled = true;
    this.NodeControl1.LeftMargin = 3;
    this.NodeControl1.ParentColumn = this.Column1;
    // 
    // NodeControl2
    // 
    this.NodeControl2.DataPropertyName = "NodeControl2";
    this.NodeControl2.IncrementalSearchEnabled = true;
    this.NodeControl2.LeftMargin = 3;
    this.NodeControl2.ParentColumn = this.Column2;
    // 
    // NodeControl3
    // 
    this.NodeControl3.DataPropertyName = "NodeControl3";
    this.NodeControl3.IncrementalSearchEnabled = true;
    this.NodeControl3.LeftMargin = 3;
    this.NodeControl3.ParentColumn = this.Column3;
}

其中tBox是NodeTextBox实例。不用说，我花了几个小时才弄明白。希望它能帮助其他人。

使用这个神奇控件的入门价格似乎是几个小时，几个小时，令人挠头的沮丧

这是您需要做的：

private void Form1_Load(object sender, EventArgs e)
{
    TreeModel _model = new TreeModel();
    treeViewAdv1.Model = _model;

    treeViewAdv1.BeginUpdate();
    for (int i = 0; i < 20; i++)
    {

        Node parentNode = new Node("root" + i);
        _model.Nodes.Add(parentNode);

        for (int n = 0; n < 2; n++)
        {
            Node childNode = new Node("child" + n);
            parentNode.Nodes.Add(childNode);
        }

    }

    NodeTextBox ntb = new NodeTextBox();
    ntb.DataPropertyName = "Text";       
    this.treeViewAdv1.NodeControls.Add(ntb);

    treeViewAdv1.EndUpdate();


}

private void Form1\u加载（对象发送方，事件参数e）
{
TreeModel_model=新的TreeModel（）；
treeViewAdv1.Model=\u Model；
treeViewAdv1.BeginUpdate（）；
对于（int i=0；i<20；i++）
{
节点parentNode=新节点（“根”+i）；
_model.Nodes.Add（parentNode）；
对于（int n=0；n<2；n++）
{
节点子节点=新节点（“子节点”+n）；
parentNode.Nodes.Add（childNode）；
}
}
NodeTextBox ntb=新的NodeTextBox（）；
ntb.DataPropertyName=“Text”；
this.treeViewAdv1.nodeControl.Add（ntb）；
treeViewAdv1.EndUpdate（）；
}

显然，这个问题很老了，但我找不到这个问题的任何答案，所以我想我会尽量避免一些人将来的挫折感

要显示多个列，请首先将UseColumns属性更改为true。
然后将所需的列添加到Columns集合属性。
接下来，使用NodeControl集合属性创建将显示的数据类型列表，以及它们的格式（复选框、文本框等）。确保设置1）DataPropertyName（稍后将使用），2）ParentColumn（显示树视图中应该显示数据的列）。 最后，创建一个从Node类继承的新类，并添加一个与每个NodeControl同名的公共属性。然后在添加节点时，使用具有正确值的新类

 private class ColumnNode: Node
        {
            public string NodeControl1="";  // This sould make the DataPropertyName specified in the Node Collection.
            public string NodeControl2 = "";
            public string NodeControl3 = "";
            public ColumnNode(string nodeControl1, string nodeControl2, int nodeControl3)
            {
                NodeControl1 = nodeControl1;
                NodeControl2 = nodeControl2;
                NodeControl3 = nodeControl3.ToString();
            }
        }

然后在添加 TreeModel_model=新的TreeModel（）

在这里指出treenodeav.Tag属性的输入是Node.Text属性，而不是Node.Tag，这可能很好。在我看来非常混乱，但过了一会儿我才发现。
