Question

我希望在其中有一个带有FormView的RadWindow对话框，我可以根据FormView的模式执行更新或插入操作。我创建了一个RadWindow对话框，添加了控件（FormView）作为内容，并通过数据绑定填充了FormView的内容。在我尝试执行保存，插入或取消操作之前，一切似乎都很好。相应的事件不会被解雇。

在我更改其模式后，似乎FormView不会调用ItemCommand或任何其他事件。有没有人有一些见解？

我设法将这个功能提取到一个简单的例子中，我只有默认页面和RadWindow。

这是我的标记：

Answer 1

将RadWindows移出RadWindowManager使用其ContentTemplates的位置。然后，您将不再需要更新面板的反射解决方法。

FormView在ChangeMode之后吃掉事件
