 二.cs

     public void CDataBind(int pageIndex) 
        {
            int pageSize = 5;//页大小
            int numCount = 0;//总记录数
            DataTable dt = null;
            try
            {
                dt = ControlInterfaceLogic.GetInterface().GetUserAndError(pageSize, pageIndex);
                DataView dv = new DataView(dt);
                DataRow[] drRowCount = dt.Select("id is not null");
                if (drRowCount.Length > 0)
                {
                    //总记录数
                    numCount = ControlInterfaceLogic.GetInterface().GetSumRow();

                    if (numCount > 0)
                    {
                        labCount.Text = numCount.ToString();
                        //当前页数
                        labPageIndex.Text = pageIndex.ToString();
                        if (numCount % pageSize == 0)
                        {
                            labPageCount.Text = (numCount / pageSize).ToString();
                        }
                        else
                        {
                            labPageCount.Text = (numCount / pageSize + 1).ToString();
                        }

                        divPage.Visible = true;
                        //数据库绑定
                        rptCErrorList.DataSource = dv;
                        rptCErrorList.DataBind();

                        rptFErrorList.DataSource = dv;
                        rptFErrorList.DataBind();
                        SetPageControl(pageIndex);
                    }
                    else
                    {
                        divPage.Visible = false;
                        rptCErrorList.DataSource = null;
                        rptCErrorList.DataBind();
                        rptFErrorList.DataSource = null;
                        rptFErrorList.DataBind();
                    }
                }
          
            }
            catch (Exception)
            {
                throw;
            }
        }

 设置分页控件可用

 void SetPageControl(int pageIndex)
        {
            if (pageIndex == 1 && pageIndex == int.Parse(labPageCount.Text))
            {
                lkFristPage.Enabled = lkBeforePage.Enabled = false;
                lkNextPage.Enabled = lkLastPage.Enabled = false;
                lkGo.Enabled = false;
            }
            else if (pageIndex == 1)
            {
                lkFristPage.Enabled = lkBeforePage.Enabled = false;
                lkNextPage.Enabled = lkLastPage.Enabled = true;
            }
            else if (pageIndex == int.Parse(labPageCount.Text))
            {
                lkFristPage.Enabled = lkBeforePage.Enabled = true;
                lkNextPage.Enabled = lkLastPage.Enabled = false;
            }
            else
            {
                lkFristPage.Enabled = lkBeforePage.Enabled = true;
                lkNextPage.Enabled = lkLastPage.Enabled = true;
            }
        }
