Question

 dev 控件 ASPxPivotGrid 分页时， 第一次点击某页可以正常翻页，再次点不能正常翻页， 报出异常：unexpected data update required ，PageIndexChanged 事件有重新绑定，没搜到答案，请高手指点。

Answer 1

你没有写RadGrid1_PageIndexChanged事件，这个事件是处理翻页功能的。参考下面代码  private int currentPageIndex;
        void RadGrid1_PageIndexChanged(object source, GridPageChangedEventArgs e)
        {
            currentPageIndex = e.NewPageIndex;
        }
        
        void RadGrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
        {
            int totalRecords = 0;
            string ip = "";
            if (!string.IsNullOrEmpty(txtIP.Text))
                ip = txtIP.Text;
            if (ip != "")
            {
                AccessLogInfo alinfo = AdminDaab.GetIPTrack(ip);
                lblIP.Text = alinfo.IP;
                lblAddDateTime.Text = alinfo.AddDateTime.ToString("yyyy-MM-dd HH:mm:ss");
                lblOS.Text = AdminTools.GetOS(alinfo.OS);
                lblBrowser.Text = alinfo.Browser;
                lblPixel.Text = alinfo.Pixel;
                lblLanguage.Text = alinfo.Languages;
                lblPageFileName.Text = alinfo.PageFileName;
                lblRefererDomain.Text = alinfo.RefererDomain;
            }
            RadGrid1.DataSource = AdminDaab.ListIPTrack(
                    ip,
                    RadGrid1.PageSize,
                    currentPageIndex,
                    ref totalRecords);
            RadGrid1.VirtualItemCount = totalRecords;
        }
