2.后台代码

        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;
                }
                if (txtNewPageIndex != null)
                {
                    newPageIndex = int.Parse(txtNewPageIndex.Text) - 1;
                }
            }
            else
            {
                newPageIndex = e.NewPageIndex;
            }
            newPageIndex = newPageIndex < 0 ? 0 : newPageIndex;
            newPageIndex = newPageIndex >= theGrid.PageCount ? theGrid.PageCount - 1 : newPageIndex;
            theGrid.PageIndex = newPageIndex;
            InfoList = AuthorizationBiz.Query(new AuthorizationInfo());
