TreeView控件的 tvFunction_AfterCheck tvFunction_BeforeCheck 事件中要注意

在这两个事件处理中,如果加设置其它的node的check状态时,

要加 if (e.Action == TreeViewAction.ByMouse)

 

        private void tvFunction_AfterCheck(object sender, TreeViewEventArgs e)
        {
            if (e.Action == TreeViewAction.ByMouse)
            {
                SetParentNodeSelect(e.Node, e.Node.Checked);
                SetChildNodeSelect(e.Node, e.Node.Checked);
            }

        }

 

要不,会造成溢出.
