实现GridView的自定义分页

GridView自带几种分页，如果不能满足要求的话，可以看看下面的代码

  <asp:GridView ID="gvNewsList" AllowPaging="true"  OnPageIndexChanging="gvNewsList_PageIndexChanging" PageSize="1" style="BORDER-RIGHT: medium none; BORDER-LEFT: medium none; WORD-BREAK: break-all" runat="server" AutoGenerateColumns="False" Width="96%" HorizontalAlign="Center" CellPadding="4" CssClass="border" ForeColor="#333333" GridLines="Both" BorderColor="black">
            <HeaderStyle BackColor="#507CD1" BorderWidth="0px" CssClass="table04bg" Font-Bold="True" ForeColor="black" />            
            <Columns>
            
                <asp:CheckBoxField HeaderText="选择" />
                <asp:BoundField DataField="Newsid" HeaderText="编号" />
                <asp:HyperLinkField DataTextField="title" HeaderText="标题" />
                <asp:BoundField DataField="ClassName" HeaderText="类别" />
                <asp:BoundField DataField="update_date" HeaderText="更新时间" />
            </Columns>
           <RowStyle BackColor="white" HorizontalAlign="center"  BorderColor="black" Font-Names="宋体"/>
            <pagertemplate>
                        <table width="100%">
                          <tr>
                            <td style="text-align:right">
                            第<asp:Label id="lblPageIndex" runat="server" text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1  %>' />页
                                共/<asp:Label id="lblPageCount" runat="server" text='<%# ((GridView)Container.Parent.Parent).PageCount  %>' />页 
                                <asp:linkbutton id="btnFirst" runat="server" causesvalidation="False" commandargument="First" commandname="Page" text="首页" />
                              <asp:linkbutton id="btnPrev" runat="server" causesvalidation="False" commandargument="Prev" commandname="Page" text="上一页" />
                             <asp:linkbutton id="btnNext" runat="server" causesvalidation="False" commandargument="Next" commandname="Page" text="下一页" />                          
                             <asp:linkbutton id="btnLast" runat="server" causesvalidation="False" commandargument="Last" commandname="Page" text="尾页" />                                            
                             <asp:textbox id="txtNewPageIndex" runat="server" width="20px" text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1  %>' />
                             <asp:linkbutton id="btnGo" runat="server" causesvalidation="False" commandargument="-1" commandname="Page" text="GO" /><!-- here set the CommandArgument of the Go Button to '-1' as the flag -->
                             </td>
                          </tr>
                        </table>
                    </pagertemplate>
                    <PagerStyle BackColor="#507CD1" BorderWidth="0px" CssClass="table04bg" Font-Bold="True" ForeColor="black" /> 

        </asp:GridView>

上面代码中<pagertemplate>与</pagertemplate>之间为自定义分页，下面看一下触发的事件代码

 1protected void gvNewsList_PageIndexChanging(object sender, GridViewPageEventArgs e)
 2        {
 3            GridView theGrid = sender as GridView;  // refer to the GridView
 4            int newPageIndex = 0;
 5
 6            if (-2 == e.NewPageIndex)
 7            { // when click the "GO" Button
 8                TextBox txtNewPageIndex = null;
 9                //GridViewRow pagerRow = theGrid.Controls[0].Controls[theGrid.Controls[0].Controls.Count - 1] as GridViewRow; // refer to PagerTemplate
10                GridViewRow pagerRow = theGrid.BottomPagerRow; //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

12
13                if (null != pagerRow)
14                {
15                    txtNewPageIndex = pagerRow.FindControl("txtNewPageIndex") as TextBox;   // refer to the TextBox with the NewPageIndex value
16                }
17
18                if (null != txtNewPageIndex)
19                {
20                    newPageIndex = int.Parse(txtNewPageIndex.Text) - 1; // get the NewPageIndex
21                }
22            }
23            else
24            {  // when click the first, last, previous and next Button
25                newPageIndex = e.NewPageIndex;
26            }
27
28            // check to prevent form the NewPageIndex out of the range
29            newPageIndex = newPageIndex <= 0 ? 0 : newPageIndex;
30            newPageIndex = newPageIndex >= theGrid.PageCount ? theGrid.PageCount-1 : newPageIndex;
31
32            // specify the NewPageIndex
33            theGrid.PageIndex = newPageIndex;
34            BindNewsList();
35            // rebind the control
36            // in this case of retrieving the data using the xxxDataSoucr control,
37            // just do nothing, because the asp.net engine binds the data automatically
38        }

注意代码中最后的内容，一定要从新绑定 GridView这样分页才能够生效
