WPF自定义Dialog模板，内容用不同的Page填充

因为审美的不同，就总有些奇奇怪怪的需求，使用框架自带的对话框已经无法满足了，这里记录一下我这边初步设计的对话框。别问为啥要用模板嵌套Page来做对话框，问就是不想写太多的窗体。。。。

使用方法(供参考):

添加用户:

User user = new User();
DialogModel dialog = new DialogModel(user, "添加用户", "Collapsed");
dialog.ShowDialog();

编辑用户(需要赋值):

 /// <summary>
 /// DataGird的自定义操作栏的编辑按钮
 /// </summary>
 /// <param name="sender"></param>
 /// <param name="e"></param>
 private void UserEdit(object sender, RoutedEventArgs e)
 {
     UserInfoDto userInfo = new UserInfoDto();
     var co = (Control)sender;
     userInfo = (UserInfoDto)co.DataContext;//获取当前行数据
     User user = new User();//实例化Page
     user.IsAdd = false;//标识是编辑
     user.Id = userInfo.Id;//将当前行信息给到Page，绑定到控件
     user.UserName = userInfo.Name;
     user.Account = userInfo.Account;
     user.PassWord = userInfo.PassWord;
     user.IsActive = userInfo.IsActive;
     user.RoleId = userInfo.RoleId;
     for (int i = 0; i < user.Roles.Count; i++)
     {
         if (user.Roles[i].Id == userInfo.RoleId)
         {
             if (user.Roles.Count > 1)
             {
                 user.Roles.Remove(user.Roles[i]);
                 user.Roles.Insert(0, user.Roles[i]);
             }
         }
     }
     DialogModel dialog = new DialogModel(user, "编辑用户", "Collapsed");
     dialog.ShowDialog();
 }
