GridView 自定义分页

在Gridview中加入
这样的PagerTemplate

                          <PagerTemplate>
                                   <div id="main">
                                      <div id="info">&nbsp;&nbsp;页次：<asp:Label ID="lblPageCurrent" runat="server" Text="1" CssClass="txtInfo"></asp:Label>
                                      /<asp:Label ID="lblPageCount" runat="server" Text="1"></asp:Label>&nbsp;&nbsp;
                                      共&nbsp;<asp:Label ID="lblPageRow" runat="server" Text="1" CssClass="txtInfo"></asp:Label>&nbsp;条记录
                                      </div>
                                      <div id="page"> 
                                          <asp:LinkButton ID="btnFirst" runat="server" CssClass="link" CommandName="Pager" CommandArgument="First" OnCommand="NavigateToPage">[首页]</asp:LinkButton>&nbsp;
                                          <asp:LinkButton ID="btnPrev" runat="server" CssClass="link" CommandName="Pager" CommandArgument="Prev" OnCommand ="NavigateToPage">[上一页]</asp:LinkButton>&nbsp;
                                          <asp:LinkButton ID="btnNext" runat="server" CssClass="link" CommandName="Pager" CommandArgument="Next" OnCommand="NavigateToPage">[下一页]</asp:LinkButton>&nbsp;
                                          <asp:LinkButton ID="btnLast" runat="server" CssClass="link" CommandName="Pager" CommandArgument="Last" OnCommand="NavigateToPage">[尾页]</asp:LinkButton>&nbsp;&nbsp;
                                          &nbsp;&nbsp;跳转到：<asp:DropDownList ID="DdlGoPage" runat="server" AutoPostBack="True" OnSelectedIndexChanged="DdlGoPage_SelectedIndexChanged" SkinID="ddlSkin"></asp:DropDownList>
                                      </div>
                                   </div>
                             </PagerTemplate> 

在后台加入这段控制分页的代码

#region//控制分页

    /***************分页用到的全局变量****************/
    int rowCount = 0;
    /*************************************************/

    protected void NavigateToPage(object sender, CommandEventArgs e)
    {
        //控制转页
        switch (e.CommandArgument.ToString())
        {
            case "First":
                this.gvMail.PageIndex = 0;
                break;
            case "Prev":
                if (this.gvMail.PageIndex > 0)
                    this.gvMail.PageIndex -= 1;
                break;
            case "Next":
                if (this.gvMail.PageIndex < (this.gvMail.PageCount - 1))
                    this.gvMail.PageIndex += 1;
                break;
            case "Last":
                this.gvMail.PageIndex = this.gvMail.PageCount - 1;
                break;
        }
        BindPageData();
    } 

    protected void gvMail_DataBound(object sender, EventArgs e)
    {
        GridViewRow pagerRow = gvMail.BottomPagerRow;
        if (pagerRow != null) //当没有记录的时候，它的值就是null所以这里要多加判断，否则会报错
        {
            //获取Label实例，显示页次信息
            Label lblCurrent = (Label)pagerRow.Cells[0].FindControl("lblPageCurrent");
            Label lblCount = (Label)pagerRow.Cells[0].FindControl("lblPageCount");
            Label lblRow = (Label)pagerRow.Cells[0].FindControl("lblPageRow");
            //获取按钮实例，为了控制其是否可用
            LinkButton btnFirstTem = (LinkButton)pagerRow.Cells[0].FindControl("btnFirst");
            LinkButton btnPrevTem = (LinkButton)pagerRow.Cells[0].FindControl("btnPrev");

            LinkButton btnLastTem = (LinkButton)pagerRow.Cells[0].FindControl("btnLast");

            if (lblCurrent != null)
                lblCurrent.Text = (this.gvMail.PageIndex + 1).ToString();
            if (lblCount != null)
                lblCount.Text = this.gvMail.PageCount.ToString();
            if (lblRow != null)
                lblRow.Text = rowCount.ToString();

            if (this.gvMail.PageIndex == 0)
            {
                btnFirstTem.Enabled = false;
                btnPrevTem.Enabled = false;
                //只有一页，所有分页按钮不可用
                if (this.gvMail.PageCount == 1)
                {
                    btnNextTem.Enabled = false;
                    btnLastTem.Enabled = false;
                }
            }
            else if (this.gvMail.PageIndex == (this.gvMail.PageCount - 1))
            {
                btnNextTem.Enabled = false;
                btnLastTem.Enabled = false;
            }
        }

    }

    protected void gvMail_RowCreated(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.Pager)
        {
            DropDownList ddl = (DropDownList)e.Row.FindControl("DdlGoPage");

            //取得记录的总数
            Mail mail = new Mail();
            DataSet mailDs = mail.GetMailCountByFloder(folderID);
            rowCount = Int32.Parse(mailDs.Tables[0].Rows[0][0].ToString());

            if (rowCount!=0)

            }
            ddl.SelectedValue = (gvMail.PageIndex + 1).ToString();

    }

    //选择页面时触发的事件  
    protected void DdlGoPage_SelectedIndexChanged(object sender, EventArgs e)
    {
        int index = int.Parse(((DropDownList)sender).SelectedValue) - 1;
        //ScriptManager.RegisterStartupScript(Page, this.GetType(), "sucess", "<script>alert('" + index + "');</script>", false);
        gvMail.PageIndex = index;
        BindPageData();
    }
    #endregion 

根据实际情况替换GridView的名称
注意gvUser_RowCreated事件中有个查询记录总数的，要依据具体的情况做相应的变化
在前台的Gridview中加入这两个事件属性

OnDataBound="gvMail_DataBound" OnRowCreated="gvMail_RowCreated"

这里的名字可以根据后台的名字做相应的变化

最后别忘了把GridView的AllowPaging设置为True
