                                </ItemTemplate>
                            </asp:Repeater>
                                </ContentTemplate>
                            </asp:UpdatePanel>后台
  protected void Repeater_quanxian_ItemCommand(object source, RepeaterCommandEventArgs e)
        {
            string userTypeName = e.CommandArgument.ToString();
            string cmd = e.CommandName;
            switch (cmd)
            {
                case "edit":
                    {
                        lab_title.Text = "编辑权限角色";
                        break;

                        if (i == -1)
                        {
                            ClientScript.RegisterStartupScript(GetType(), "错误", "<script>alert('请先删除该类型用户后再操作');</script>");
                            //Page.RegisterClientScriptBlock("a", "<script>alert('请先删除该类型用户后再操作');</script>");
                        }
                        else
                        {
                            DB();
                        }
                        break;
                    }
                default:
                    {
                        break;
                    }
            }
        }edit的时候 我在前台调用了一个js（弹出div层） OnClientClick="showEdit()"，
但是就马上刷新界面 层又隐藏了。
请问下 怎么样我的层才不会隐藏掉啊，无刷新没有效果
