【Asp.Net】 GridView分页，C#源代码
作者:Dezai.CN / 发布于2013/1/4/ 623
前台代码：
写入到
<asp:GridView>  
</asp:GridView>   
<PagerTemplate> 
               当前页：<asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label> 
                                                               
              总页数：<asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label> 
                
                <asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page"
                    Visible='<%#((GridView)Container.NamingContainer).PageIndex != 0 %>'>首页</asp:LinkButton> 
                <asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev"
                    CommandName="Page" Visible='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>'>上一页</asp:LinkButton> 
                  
                <asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"
                    Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>下一页</asp:LinkButton> 
                <asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"
                    Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>尾页</asp:LinkButton> 
                   
                <asp:TextBox ID="txtNewPageIndex" runat="server" Width="20px" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' />页 
                   
                <asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="-2"
                    CommandName="Page" Text="GO" /> 
            </PagerTemplate>

后台代码：
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) 
    { 
        // 得到该控件 
        GridView theGrid = sender as GridView; 
        int newPageIndex = 0; 
        if (e.NewPageIndex == -3) 
        { 
            //点击了Go按钮 
            TextBox txtNewPageIndex = null; 
    
            //GridView较DataGrid提供了更多的API，获取分页块可以使用BottomPagerRow 或者TopPagerRow，当然还增加了HeaderRow和FooterRow 
            GridViewRow pagerRow = theGrid.BottomPagerRow; 
    
            if (pagerRow != null) 
            { 
                //得到text控件 
                txtNewPageIndex = pagerRow.FindControl("txtNewPageIndex") as TextBox; 
            } 
            if (txtNewPageIndex != null) 
            { 
                //得到索引 
                newPageIndex = int.Parse(txtNewPageIndex.Text) - 1; 
            } 
        } 
        else
        { 
            //点击了其他的按钮 
            newPageIndex = e.NewPageIndex; 
        } 
        //防止新索引溢出 
        newPageIndex = newPageIndex < 0 ? 0 : newPageIndex; 
        newPageIndex = newPageIndex >= theGrid.PageCount ? theGrid.PageCount - 1 : newPageIndex; 
    
        //得到新的值 
        theGrid.PageIndex = newPageIndex; 
    
        //重新绑定 
        bind2Gridview(); 
    }
