推荐答案

的解决方案 AfterSelect（）事件仅触发新选择，如果已选中则不会触发。您可能希望捕获TreeView的Click事件。 The AfterSelect() event only fires for new selections and won't fire if already selected. You may want to capture the TreeView's Click event instead. private void treeView1_Click(object sender, EventArgs e) { TreeViewHitTestInfo info = treeView1.HitTest(treeView1.PointToClient(Cursor.Position)); if (info != null) MessageBox.Show(info.Node.Text); }

编辑： 以下是我认为你试图做的事情：

Here is what I think that you are attempting to do:

private void treeView1_Click(object sender, EventArgs e) { TreeViewHitTestInfo info = treeView1.HitTest(treeView1.PointToClient(Cursor.Position)); if (info != null) { comboBox1.DisplayMember = "Text"; comboBox1.DataSource = info.Node.Nodes; } } private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) { var node = comboBox1.SelectedItem as TreeNode; if (node == null) return; treeView1.SelectedNode = node; treeView1.Focus(); }
