在Windows Forms中,TreeListView
控件是一个自定义控件,它结合了 ListView
和 TreeView
的功能
首先,确保已经安装了ObjectListView库。如果没有,请访问以下链接进行下载和安装:http://objectlistview.sourceforge.net/cs/index.html
向项目添加对ObjectListView库的引用。在解决方案资源管理器中,右键单击项目名称,然后选择“添加引用”。在“引用管理器”窗口中,找到并添加ObjectListView库。
在工具箱中添加TreeListView控件。右键单击工具箱,然后选择“选择项”。在“选择工具箱项”窗口中,找到并添加TreeListView控件。
将TreeListView控件从工具箱拖放到窗体上。
创建一个类来表示数据模型。例如,如果你要显示员工信息,可以创建一个Employee类:
public class Employee { public string Name { get; set; } public string Position { get; set; } public List<Employee> Subordinates { get; set; } }
- 为TreeListView控件设置列。在窗体的Load事件或构造函数中,添加以下代码:
treeListView1.Columns.Add(new OLVColumn("Name", "Name")); treeListView1.Columns.Add(new OLVColumn("Position", "Position"));
- 创建一个包含数据的列表,并将其分配给TreeListView控件的Roots属性。例如:
List<Employee> employees = new List<Employee> { new Employee { Name = "Alice", Position = "Manager", Subordinates = new List<Employee> { new Employee { Name = "Bob", Position = "Developer" }, new Employee { Name = "Charlie", Position = "Developer" } } }, new Employee { Name = "David", Position = "Manager", Subordinates = new List<Employee> { new Employee { Name = "Eve", Position = "Developer" } } } }; treeListView1.Roots = employees;
- 若要显示子节点,需要处理TreeListView控件的CanExpandGetter和ChildrenGetter事件。在窗体的Load事件或构造函数中,添加以下代码:
treeListView1.CanExpandGetter = delegate (object row) { Employee employee = row as Employee; return employee?.Subordinates?.Count > 0; }; treeListView1.ChildrenGetter = delegate (object row) { Employee employee = row as Employee; return employee?.Subordinates; };
现在,TreeListView控件应该已经成功绑定到数据。运行应用程序,你应该能看到一个包含员工信息的树形列表视图。
