页面按钮，放到缓存中。再次刷新页面，操作按钮的属性就失效了，不知道为什么啊？求高手
问题描述：获取页面的所有的LinkButton放到Dictionary<string, LinkButton>中，之后在把Dictionary<string, LinkButton>放到缓存中。第一次执行，按钮LinkButton2可以隐藏，再次刷新之后按钮LinkButton2会显示出来，调试结果是执行了LinkButton2.Visible=false。不知道哪里的问题啊？请高手指点指点。
页面代码
<asp:LinkButton ID="LinkButton1" runat="server">LinkButton1</asp:LinkButton>
<asp:LinkButton ID="LinkButton2" runat="server">LinkButton2</asp:LinkButton>
<asp:LinkButton ID="LinkButton3" runat="server">LinkButton3</asp:LinkButton>
protected void Page_Load(object sender, EventArgs e)
{
foreach (KeyValuePair<string, LinkButton> item in GetPageControl())
{
if (item.Key.Contains("LinkButton2"))
{
item.Value.Visible = false;
}
}
}
private Dictionary<string, LinkButton> GetPageControl()
{
string CacheKey = "aaaaa";
object objDic = Common.DataCache.GetCache(CacheKey);
if (objDic == null)
{
try
{
Dictionary<string, LinkButton> dic = new Dictionary<string, LinkButton>();
foreach (Control childc in Page.Form.Controls)
{
if (childc is LinkButton)
{
dic.Add(childc.ID, childc as LinkButton);
}
}
objDic = dic;
if (objDic != null)
{
int cacheDic = Common.ConfigHelper.GetConfigInt("AdminPageControl");
Common.DataCache.SetCache(CacheKey, objDic, DateTime.Now.AddMinutes(cacheDic), TimeSpan.Zero);
}
}
catch { return null; }
}
return objDic as Dictionary<string, LinkButton>;
}
