用户控件 (ascx) 和属性 [英] User control (ascx) and properties

问题描述

The only way I've found to persist property values within a user control is to use the ViewState.

public string Title {
        get { return Convert.ToString(ViewState["Title"]); }
        set { ViewState["Title"] = value; }
    }

I can't say I'm real impressed with this though, as the more properties a user control has the more crap you'll be sticking in the ViewState. Is there a better way to persist properties?

解决方案

It depends. If you need to property values to be persisted beyond a post-back then you'll either have to use ViewState or Session. Since those controls are re-created on each post back you can't really maintain that state otherwise.
