如何在C＃Winforms应用程序中创建这样的MultiColumn树视图？

Parent Col1 Col2 Col3 | |____ Child Data1 Data2 Data3 | |____ Child2 Data1 Data2 Data3 

Answer 1

使用ObjectListView库，function非常强大且易于使用。

这是一个完整的例子：

1）编译ObjectListView源代码以获取ObjectListView.dll
2）创建一个新的Windows窗体应用程序并添加ObjectListView.dll作为参考
3）打开Form1.cs代码并复制以下代码：

 public partial class Form1 : Form { // embedded class class Node { public string Name { get; private set; } public string Column1 { get; private set; } public string Column2 { get; private set; } public string Column3 { get; private set; } public List Children { get; private set; } public Node(string name, string col1, string col2, string col3) { this.Name = name; this.Column1 = col1; this.Column2 = col2; this.Column3 = col3; this.Children = new List(); } } // private fields private List data; private BrightIdeasSoftware.TreeListView treeListView; // constructor public Form1() { InitializeComponent(); AddTree(); InitializeData(); FillTree(); } // private methods private void FillTree() { // set the delegate that the tree uses to know if a node is expandable this.treeListView.CanExpandGetter = x => (x as Node).Children.Count > 0; // set the delegate that the tree uses to know the children of a node this.treeListView.ChildrenGetter = x => (x as Node).Children; // create the tree columns and set the delegates to print the desired object proerty var nameCol = new BrightIdeasSoftware.OLVColumn("Name", "Name"); nameCol.AspectGetter = x => (x as Node).Name; var col1 = new BrightIdeasSoftware.OLVColumn("Column1", "Column1"); col1.AspectGetter = x => (x as Node).Column1; var col2 = new BrightIdeasSoftware.OLVColumn("Column2", "Column2"); col2.AspectGetter = x => (x as Node).Column2; var col3 = new BrightIdeasSoftware.OLVColumn("Column3", "Column3"); col3.AspectGetter = x => (x as Node).Column3; // add the columns to the tree this.treeListView.Columns.Add(nameCol); this.treeListView.Columns.Add(col1); this.treeListView.Columns.Add(col2); this.treeListView.Columns.Add(col3); // set the tree roots this.treeListView.Roots = data; } private void InitializeData() { // create fake nodes var parent1 = new Node("PARENT1", "-", "-", "-"); parent1.Children.Add(new Node("CHILD_1_1", "A", "X", "1")); parent1.Children.Add(new Node("CHILD_1_2", "A", "Y", "2")); parent1.Children.Add(new Node("CHILD_1_3", "A", "Z", "3")); var parent2 = new Node("PARENT2", "-", "-", "-"); parent2.Children.Add(new Node("CHILD_2_1", "B", "W", "7")); parent2.Children.Add(new Node("CHILD_2_2", "B", "Z", "8")); parent2.Children.Add(new Node("CHILD_2_3", "B", "J", "9")); var parent3 = new Node("PARENT3", "-", "-", "-"); parent3.Children.Add(new Node("CHILD_3_1", "C", "R", "10")); parent3.Children.Add(new Node("CHILD_3_2", "C", "T", "12")); parent3.Children.Add(new Node("CHILD_3_3", "C", "H", "14")); data = new List { parent1, parent2, parent3 }; } private void AddTree() { treeListView = new BrightIdeasSoftware.TreeListView(); treeListView.Dock = DockStyle.Fill; this.Controls.Add(treeListView); } }

http://www.go-mono.com/mono-downloads/download.html ..为你的操作系统下载Gtksharp并在​​visual studio中添加这些dll的参考资料atk-sharp.dll，gdk-sharp.dll，glib- sharp.dll，gtk-sharp.dll并使用Gtk; …你将获得TreeView

  public class TreeViewExample { public static void Main() { Gtk.Application.Init(); new TreeViewExample(); Gtk.Application.Run(); } public TreeViewExample() { Gtk.Window window = new Gtk.Window("TreeView Example"); window.SetSizeRequest(500, 200); Gtk.TreeView tree = new Gtk.TreeView(); window.Add(tree); Gtk.TreeViewColumn Parent = new Gtk.TreeViewColumn(); Parent.Title = "Parent"; Gtk.CellRendererText Parent1 = new Gtk.CellRendererText(); Parent.PackStart(Parent1, true); Gtk.TreeViewColumn ChildColoumn1 = new Gtk.TreeViewColumn(); ChildColoumn1.Title = "Column 1"; Gtk.CellRendererText Child1 = new Gtk.CellRendererText(); ChildColoumn1.PackStart(Child1, true); Gtk.TreeViewColumn ChildColumn2 = new Gtk.TreeViewColumn(); ChildColumn2.Title = "Column 2"; Gtk.CellRendererText Child2 = new Gtk.CellRendererText(); ChildColumn2.PackStart(Child2, true); tree.AppendColumn(Parent); tree.AppendColumn(ChildColoumn1); tree.AppendColumn(ChildColumn2); Parent.AddAttribute(Parent1, "text", 0); ChildColoumn1.AddAttribute(Child1, "text", 1); ChildColumn2.AddAttribute(Child2, "text", 2); Gtk.TreeStore Tree = new Gtk.TreeStore(typeof(string), typeof(string), typeof(string)); Gtk.TreeIter iter = Tree.AppendValues("Parent1"); Tree.AppendValues(iter, "Child1", "Node 1"); iter = Tree.AppendValues("Parent2"); Tree.AppendValues(iter, "Child1", "Node 1","Node 2"); tree.Model = Tree; window.ShowAll(); } }
