    public String Test
    {
        get
        {
            if (ViewState["Test"] == null)
            {
                ViewState["Test"] = String.Empty;
            }
            return ViewState["Test"].ToString();
        }
        set
        {
            ViewState["Test"] = value;
        }
    }

public void Page_Load(object sender,EventArgs e)
{
    if (!Page.IsPostBack)
    {
        this.Test = "Test";
    }
}
</script>
<asp:CheckBox runat="server" AutoPostBack="true" />

当我加载页面时,ViewState [“Test”]被分配给“Test”,但是当我选中复选框时,页面会进行回发并且ViewState [“Test”]再次为null.我错过了什么？

-Update-

因此,即使我在页面中设置EnableViewState = true,并且主页面中的控件EnableViewState为false.我不得不补充一下

this.Page.Master.EnableViewState = true;

控制让它工作.

谢谢您的帮助！
