我的树形菜单

 

 

 

       ItemCollection tv_all = trees.Items;  //得到树形菜单里的东西       集合
         
            foreach (var item in tv_all)
            {
                TreeView tv = item as TreeView;
                foreach (var FList in tv.Items)
                {
                    TreeViewItem tvt = FList as TreeViewItem;
                    CheckBox F_ck = tvt.Header as CheckBox; //父级菜单的多选框
                    if (F_ck.IsChecked == null || F_ck.IsChecked.Value)
                    {
                        if (F_ck.IsChecked != null)
                        {
                            FatherList.Add(F_ck.Tag.ToString());
                        }
                        NewCk_Content.Add(F_ck.Content.ToString());
                        foreach (var C_item in tvt.Items)
                        {
                            CheckBox C_ck = C_item as CheckBox;  //子菜单的多选框
                            if (C_ck.IsChecked.Value)
                            {
                                NewCk_Content.Add("---" + C_ck.Content.ToString());
                                if (F_ck.IsChecked != null && !F_ck.IsChecked.Value)
                                {
                                    SonList.Add(C_ck.Tag.ToString());   //tag属性中存储了ID
                                }
                            }
                        }
                    }
