想做外贸去哪个网站做成人本科

如下图，可编辑的DataGrid，如果有操作按钮，则最后一行会异常出现按钮；解决办法就是让代码动态生成按钮；

动态生成按钮主要代码：

 //按钮的StackPanel加载完成private void btnList_Loaded(object sender, RoutedEventArgs e){//ShowAlertHelpter.ShowAlert("按钮容器加载完成");var conqi = sender as StackPanel;if (conqi == null || conqi.Tag == null || conqi.Tag.ToString() == "0"){return;}var row = conqi.Parent;Button button = new Button();button.Content = "重置密码";button.Click += ResetPassword_Click;button.Tag = conqi.Tag;conqi.Children.Add(button);Button button2 = new Button();button2.Content = "上传电子签名";button2.Click += BtnImgName_Click;button2.Tag = conqi.Tag;conqi.Children.Add(button2);Button button3 = new Button();button3.Content = "删除";button3.Click += del_Click;button3.Tag = conqi.Tag;conqi.Children.Add(button3);}
