故事：
我正在开发一个图表，显示假期（年假、已用假期”等），用于从组合框中选择一年、业务单位和部门，到目前为止，我很高兴它的工作结果...但是如果在一段时间后在这个部门之间切换我会得到这个奇怪的错误...... *
此页面的状态信息无效，可能已损坏。
[没有相关的源代码行]
所以我向下滚动了一点，发现了这个
[ViewStateException: Invalid viewstate. Client IP: ::1 Port: 27968 Referer: http://localhost/HolidayTracker/Report/VacationChart.aspx Path: /HolidayTracker/Report/VacationChart.aspx User-Agent: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0) ViewState: ....
所以我检查了我的视图状态，我没有发现错误或其他什么..
private HtBusinessUnit selectedBU
{
get
{
return (HtBusinessUnit)ViewState["selectedBu"];
}
set
{
ViewState["selectedBu"] = value;
}
}
private HtDepartment selectDep
{
get
{
return (HtDepartment)ViewState["selectedDep"];
}
set
{
ViewState["selectedDep"] = value;
}
}
private string selectedYear
{
get
{
return ViewState["selectedYear"] != null ? ViewState["selectedYear"].ToString() : "";
}
set
{
ViewState["selectedYear"] = value;
}
}
这是错误消息
