自定义GridView 分页控件

该分页控件非常方便，只要拖进来即可使用，而其样式等都很好看，希望能够对大家有所帮助

下面是使用方法,实现的效果为：

 

 

1、aspx页面中只要拖进来GridViewnavigation.ascx页面即可

 <uc2:GridViewnavigation ID="GridViewnavigation1" runat="server" />

 

2、cs页面中的在页面加载中调用

SetDivePage();

 //分页
    private void SetDivePage()
    {
        GridView1.AllowPaging = true;
        GridView_cyh.BindDataDelegate f = new GridView_cyh.BindDataDelegate(Bind);//修改这个dataBind,让f 指向你的方法。
        GridViewnavigation1.SetTarget(GridView1, f, 2);

    }

注意：

SetDivePage();不要放到if (!Page.IsPostBack){  }中

 

 

3、下面是GridViewnavigation.ascx的源码

 

GridViewnavigation.ascx

 

<%@ Control Language="c#" Inherits="GridView_cyh.GridViewnavigation" CodeFile="GridViewnavigation.ascx.cs" %><TABLE id="Table1" cellSpacing="0" cellPadding="0" width="100%" border="0"><TR><TD vAlign="bottom" style="height: 25px">页次：<strong><font color="blue"><asp:label id="PageNumber" runat="server">6/6</asp:label></font></strong>页 每页：<strong><font color="blue"><asp:label id="PageBulk" runat="server">20</asp:label></font></strong>总记录数：<strong><font color="blue"><asp:Label id="RecordNumber" runat="server">120</asp:Label></font></strong></TD><TD vAlign="bottom" align="center" style="height: 25px"><asp:ImageButton id="First" runat="server" ImageUrl="../images/home.gif" ImageAlign="AbsMiddle" CausesValidation="False"></asp:ImageButton><asp:ImageButton id="Previous" runat="server" ImageUrl="../images/priv.gif" ImageAlign="AbsMiddle"CausesValidation="False" ></asp:ImageButton><asp:ImageButton id="Next" runat="server" ImageUrl="../images/next.gif" ImageAlign="AbsMiddle" CausesValidation="False"></asp:ImageButton><asp:ImageButton id="Lastly" runat="server" ImageUrl="../images/end.gif" ImageAlign="AbsMiddle" CausesValidation="False"></asp:ImageButton>转到<asp:TextBox id="SelectPage" runat="server" Width="30px" CssClass="input"></asp:TextBox><asp:ImageButton id="ImageButton1" runat="server" ImageUrl="../images/qd.gif" ImageAlign="AbsMiddle"CausesValidation="False"></asp:ImageButton></TD></TR></TABLE>
