c# - 如何使用 ObjectListView 库处理单击事件？

Question

我正在尝试使用 TreeListView，我看到了这篇文章：如何在 C# Winforms 应用程序中创建这样的多列树视图？. 但是我不明白当我点击树节点时如何处理事件。你可以帮帮我吗？

我试图添加这样的事件来形成：

private void treeListView_Click(object sender, EventArgs e){
    Debug.Print("HI");
}

但它不起作用。

感谢@Robert Harvey 的回答，我补充说

treeListView.CellClick += treeListView_CellClick; 进入 FillTree 方法，其中

private void treeListView_CellClick(object sender, BrightIdeasSoftware.CellClickEventArgs e)
        {
            Debug.Print("hi");
        }

该帖子使用ObjectListView 库。如果您下载该库的源代码，在 Visual Studio 中打开它并检查 Events.cs，您会在 TreeListView 的部分类中找到它：

/// <summary>
/// This event is triggered when user input requests the expansion of a list item.
/// </summary>
[Category("ObjectListView"),
Description("This event is triggered when a branch is about to expand.")]
public event EventHandler<TreeBranchExpandingEventArgs> Expanding;

/// <summary>
/// This event is triggered when user input requests the collapse of a list item.
/// </summary>
[Category("ObjectListView"),
Description("This event is triggered when a branch is about to collapsed.")]
public event EventHandler<TreeBranchCollapsingEventArgs> Collapsing;

/// <summary>
/// This event is triggered after the expansion of a list item due to user input.
/// </summary>
[Category("ObjectListView"),
Description("This event is triggered when a branch has been expanded.")]
public event EventHandler<TreeBranchExpandedEventArgs> Expanded;

/// <summary>
/// This event is triggered after the collapse of a list item due to user input.
/// </summary>
[Category("ObjectListView"),
Description("This event is triggered when a branch has been collapsed.")]
public event EventHandler<TreeBranchCollapsedEventArgs> Collapsed;

该文件中还为类本身定义了一堆事件ObjectListView，包括这个：

/// <summary>
/// Triggered when a cell is left clicked.
/// </summary>
[Category("ObjectListView"),
Description("This event is triggered when the user left clicks a cell.")]
public event EventHandler<CellClickEventArgs> CellClick;
