Question

我正在开发一个有几台雷达台的网页的网站,用户可以选择他们想要展示的具体控制,并能够安排这种控制。

我在增加/移动/移动(改变控制树)时,看到了许多观点错误,唯一的解决办法似乎是为某些电离层连续器(RadDock、RadDockLayout、RadDockZone等)和适用[国家ModeById]的特性设置了包装班。

[ViewStateModeById]
public class RadDockById : RadDock

Has anyone used RadDock in conjunction with ViewStateModeById? Is it likely to cause any trouble down the line?

Answer 1

The ViewState related problems that you have encountered are most probably caused by the following two things:

The dynamically created RadDock s are not added to the same control. Once they are added to the RadDockZone s and other times to RadDockLayout. This causes the incorrect ViewState to be loaded for some of the docks which is causing the problem.
The closed docks are disposed and removed from the page. This again changes the Controls tree of the Page, which is essential when loading and saving the ViewState.

你在解决这个问题方面有以下选择:

Disabling the ViewState for the RadDockLayout or entire page. This way you can add or remove controls, but if the properties are changed dynamically there might be some problems.
Creating a new class that inherits from the RadDock control and marking it to use ViewStateModeById, as you have guessed. In this forum thread you can find more information about this approach.
At all times creating all docks and adding them to the RadDockLayout. The closed RadDocks should always have their Visible property set to false.
