使用了Literal空间获取不到值

HTML code

<asp:Literal ID="litId" runat="server" Visible="False"></asp:Literal>

C# code

            T_FuncList tmodel = new T_FuncList();            tmodel.Id = litId.Text != "" ? Convert.ToInt32(litId.Text) : 0;            tmodel.FuncName = txtFuncName.Text;            tmodel.FuncNameEN = txtFuncNameEn.Text;            tmodel.Url = txtUrl.Text;            tmodel.Location = txtLocation.Text;            int result = funll.SetFuncList(tmodel);            if (result > 0)            {                txtFuncName.Text = "";                txtFuncNameEn.Text = "";                txtUrl.Text = "";                txtLocation.Text = "";            }            Bind();

[解决办法]
Literal 控件只用来显示的，不能得到值，
要得到值请使用HiddenField控件
