C# TreeView 连续点击 不触发AfterCheck事件

创建一个类 TreeView2

namespace System.Windows.Forms
{
    public class TreeView2 : TreeView
    {
        protected override void WndProc(ref Message m)
        {
            if (m.Msg != 0x203)
            {
                base.WndProc(ref m);
            }
        }
    }
}

然后前台放置一个TreeView控件。名叫：treeView1

后台代码：

private void Form3_Load(object sender, EventArgs e)
        {
            //测试数据
            TreeNode t = new TreeNode();
            t.Text = "所有权限";

            TreeNode t1 = new TreeNode();
            t1.Text = "会员消费";
            t.Nodes.Add(t1);

            for (int i = 0; i < 100; i++)
            {
                TreeNode t2 = new TreeNode();
                t2.Text = "Test" + i;
                t1.Nodes.Add(t2);
            }

            this.treeView1.CheckBoxes = true;
            this.treeView1.Nodes.Add(t);

        }

        private void CheckAllChildNodes(TreeNode treeNode, bool nodeChecked)
        {
            foreach (TreeNode node in treeNode.Nodes)
            {
                node.Checked = nodeChecked;
                if (node.Nodes.Count > 0)
                {
                    this.CheckAllChildNodes(node, nodeChecked);
                }
            }
        }

        private void treeView1_AfterCheck(object sender, TreeViewEventArgs e)
        {
            if (e.Action != TreeViewAction.Unknown)
            {
                if (e.Node.Nodes.Count > 0)
                {
                    this.CheckAllChildNodes(e.Node, e.Node.Checked);
                }
            }
        }

最后，将Form3.Designer.cs 文件中的 TreeView
全部替换成我们的 TreeView2
