        protected void gvAuthManagement_PageIndexChanging(object sender, GridViewPageEventArgs e)

        {

            GridView theGrid = sender as GridView;

            int newPageIndex = 0;

            if (e.NewPageIndex == -2)

            {

                TextBox txtNewPageIndex = null;

                GridViewRow pagerRow = theGrid.BottomPagerRow;

                if (pagerRow != null)

                {

                    txtNewPageIndex = pagerRow.FindControl("txtNewPageIndex") as TextBox;

            }

            newPageIndex = newPageIndex < 0 ? 0 : newPageIndex;

            newPageIndex = newPageIndex >= theGrid.PageCount ? theGrid.PageCount - 1 : newPageIndex;

            theGrid.PageIndex = newPageIndex;

            InfoList = AuthorizationBiz.Query(new AuthorizationInfo());
