GridView的PagerTemplate分页(二)

1、开启GridView的分页功能AllowPaging为Ture.

在Html源设置GridView的PagerTemplate：

<asp:GridView ID="gvCustom" runat="server" BorderColor="Gray" Height="20px" Width="98%" AllowPaging="True" AutoGenerateColumns="False" OnPageIndexChanging="gvCustom_PageIndexChanging" OnRowDataBound="gvCustom_RowDataBound" EmptyDataText="没有符合查询条件的数据！" OnDataBound="gvCustom_DataBound" OnRowDeleting="gvCustom_RowDeleting">
                                    <EditRowStyle BackColor="SeaGreen" />
                                    <SelectedRowStyle BorderColor="SeaGreen" />
                                    <HeaderStyle BackColor="#718BD6" Font-Size="Small" ForeColor="White" Height="20px" />
                                    <PagerSettings Mode="NumericFirstLast" />
                                    <RowStyle Height="16px" />
                                    <AlternatingRowStyle BackColor="#EDF5FF" />
                                    <Columns>
                                        <asp:BoundField DataField="CustomID" HeaderText="客户ID" Visible="False" />
                                        <asp:BoundField DataField="CustomName" HeaderText="客户名称" />
                                        <asp:BoundField DataField="CustomType" HeaderText="客户类型" />
                                        <asp:BoundField DataField="UserName" HeaderText="销售员" />
                                        <asp:BoundField DataField="LinkMan" HeaderText="联系人" />
                                        <asp:BoundField DataField="Tel" HeaderText="联系电话" />
                                        <asp:HyperLinkField DataNavigateUrlFields="CustomID" DataNavigateUrlFormatString="CustomInfo.aspx?CustomID={0}"
                                            HeaderText="查看" Text="详细信息" />
                                        <asp:TemplateField HeaderText="删除">
                                            <ItemTemplate>
                                                <asp:ImageButton ID="lbtnDelete" runat="server" CommandName="Delete" ImageUrl="~/Images/drop.gif" />
                                            </ItemTemplate>
                                        </asp:TemplateField>
                                    </Columns>
                                    <EmptyDataRowStyle ForeColor="Red" />
                                    
                                    <PagerTemplate>
            页面大小：<%# this.gvCustom.PageSize %> 条记录
            <asp:LinkButton ID="lbtnPrev" Text="上一页" CommandArgument="p" OnCommand="LinkPageChanged" runat="server"></asp:LinkButton>
            <asp:LinkButton ID="lbtnNext" Text="下一页" CommandArgument="n" OnCommand="LinkPageChanged" runat="server"></asp:LinkButton>
             转到
            <asp:DropDownList ID="ddl"  runat="server" AutoPostBack="true" OnSelectedIndexChanged="DropPageChanged">
            </asp:DropDownList>页 
            页面信息：第<%# this.gvCustom.PageIndex + 1 %>页/共<%# this.gvCustom.PageCount%>页
            </PagerTemplate>
                                    
                                </asp:GridView>

 

添加后台事件(共3个事件，Copy一下代码即可)：

 

protected void LinkPageChanged(object sender, EventArgs e)
    {
        LinkButton lb = sender as LinkButton;
        //上一页和下一页
        if (lb.CommandArgument == "p")
        {
            if (this.gvCustom.PageIndex > 0)
                this.gvCustom.PageIndex--;
        }
        else if (lb.CommandArgument == "n")
        {
            this.gvCustom.PageIndex++;
        }
        this.BindCustomList();
    }

    protected void DropPageChanged(object sender, EventArgs e)
    {
        DropDownList ddl = sender as DropDownList;
        this.gvCustom.PageIndex = int.Parse(ddl.SelectedValue);
        this.BindCustomList();
    }

    protected void gvCustom_DataBound(object sender, EventArgs e)
    {
        //上一页按钮是否可用
        LinkButton lbp = this.gvCustom.BottomPagerRow.Cells[0].FindControl("lbtnPrev") as LinkButton;
        if (this.gvCustom.PageIndex-1 < 0)
            lbp.Enabled = false;
        else
            lbp.Enabled = true;
        //下一页按钮是否可用
        LinkButton lbn = this.gvCustom.BottomPagerRow.Cells[0].FindControl("lbtnNext") as LinkButton;
        if (this.gvCustom.PageIndex + 1 < this.gvCustom.PageCount )
            lbn.Enabled = true;
        else
            lbn.Enabled = false;

        //绑定总页数
        DropDownList ddl = this.gvCustom.BottomPagerRow.Cells[0].FindControl("ddl") as DropDownList;

        for (int i = 0; i < this.gvCustom.PageCount; i++)
        {
            ddl.Items.Add(new ListItem((i + 1).ToString(), i.ToString()));
        }
        ddl.SelectedIndex = this.gvCustom.PageIndex;
    }

 

试试看效果怎么样吧:)
