如何将用户控件分配给后面的扩展代码？

Question

I have a series of ASP.NET pages that are pretty much the same, except for some abstract properties in the code behind.

Each page (/default.aspx) includes a user control:

<UI:SingleRaterControl runat="server" />

Previously, the various code behinds were copy and pastes of essentially the same thing. In each version of /default.aspx.cs there was a protected property that would hold the user control.

public class _default: SingleRaterBase
{
    protected SingleRaterControl singleRaterControl;
    ...
}

In an effort to reduce the amount of code I have to maintain, I created at abstract class called EProfileDefault that would hold all the common code of the _default classes (each _default class is in a different namespace).

So now I have

public abstract class EProfileDefault: SingleRaterBase
{
    protected SingleRaterControl singleRaterControl;
    ...
}

and each _default class has

public class _default : EProfileDefault
{
    ...
}

However, the SingleRaterControl is no longer getting automatically assigned to the code behind.

Is this because ASP.NET magic will only automatically assign the user control to the immediate instance of the code behind class, as long as it has the same name (as suggested by this article )?

If so, is it possible to manually find and assign the user control?

如@aquinas所建议，给控件一个ID，然后该控件将被分配给与该控件的ID同名的受保护属性。
