在权限管理中要设置用户的权限：
具体是通过勾选住checkbox复选框（几十个）来实现的。
将勾选住的复选框的值循环插入数据库，在选择用户的时候把该用户所拥有的权限读取出来以复选框的形式显示出来。
这个过程怎么实现啊？
请大家多多指点，多谢各位！

我现在想知道怎样才能在后台将从数据库中读取出来的权限值与checkbox的value值作比较如果两个值相同就让该checkbox选中。我现在在后台无法找到前台的checkbox，无法循环读取。
代码如下：
protected void ddlSubUserList_SelectedIndexChanged(object sender, EventArgs e)
{
UserAccessBLL bll = new UserAccessBLL();
string userId = ddlSubUserList.SelectedItem.Value.ToString();
List<Acs_UserAccess> uaList = bll.GetUserAccessByUserId(Convert.ToInt32(userId));
for (int i = 0; i < uaList.Count; i++)
{
foreach (Control ct in form1.Controls)
{
if (ct.GetType().ToString().Equals("System.Web.UI.HtmlControls.HtmlInputCheckBox"))
{
HtmlInputCheckBox cb = (HtmlInputCheckBox)ct;
if ((cb.Value.ToString()).Equals((uaList[i].ToString())))
{
cb.Checked = true;
}
}
}
}
}
该代码走到第一个if语句：
if (ct.GetType().ToString().Equals("System.Web.UI.HtmlControls.HtmlInputCheckBox"))
就不走了，进入不到if里。
请问大家这是怎么回事啊？
