Silverlight 3 Toolkit DataForm - 未启用取消功能？

发布于 2024-08-13 20:05:23 字数 653 浏览 6 评论 0原文

我有一个 Silverlight 3 datakit:DataForm 通过 ItemsSource 绑定到 ADO.NET Data Service 1.5 CTP2 数据源。下面是一个片段...

var programs = DataServiceCollection.CreateTracked(
              dashboardService, query.EndExecute(asyncResult));
this.ProgramEditForm.ItemsSource = programs;

我的 DataForm 定义非常简单...

<"ProgramEditForm"
 CommandButtonsVisibility="All"
 AutoCommit="False"
 AutoEdit="False"/>

我关闭了 AutoEdit 和 AutoCommit，因为我希望用户有半模式的感觉，明确发起更改，然后明确接受最终结果。这就是一切变得糟糕的地方。

当用户点击铅笔图标开始编辑时，“确定”按钮会亮起，但取消按钮不会亮起。由于导航图标在编辑期间被禁用（没有自动提交），因此除了更改数据库之外，用户无法退出编辑。

这是 ADO.NET 的产物吗？

谢谢！

I have a Silverlight 3 datakit:DataForm bound to a ADO.NET Data Service 1.5 CTP2 datasource via the ItemsSource. A fragment is below...

var programs = DataServiceCollection.CreateTracked(
              dashboardService, query.EndExecute(asyncResult));
this.ProgramEditForm.ItemsSource = programs;

My DataForm definition is dead simple...

<"ProgramEditForm"
 CommandButtonsVisibility="All"
 AutoCommit="False"
 AutoEdit="False"/>

I have AutoEdit and AutoCommit off because I want the semi-modal feel of the user havign to explicity initiate a change, and then specifically accept the final results. And thats where it all goes bad.

When the user hits the pencil icon to initiate an edit, the OK button lights up but NEVER the cancel button. Since the navigation icons are disabled during edit (without autocommit) then the user has no way, other than changing the database, to back out of the edit.

Is this an artifact of the ADO.NET stuff?

Thanks!
