gridview实现分页

發(fā)布時間:2023/12/4 编程问答 33 豆豆
生活随笔 收集整理的這篇文章主要介紹了 gridview实现分页 小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

前臺代碼:

<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
??????????? AutoGenerateColumns="False" DataKeyNames="ScoreID"
??????????? DataSourceID="SqlDataSource1" onpageindexchanging="GridView1_PageIndexChanging"?
??????????? Width="100%" EmptyDataText="沒有數(shù)據(jù)記錄!"
??????????? BackColor="White" BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px"
??????????? CellPadding="3" GridLines="Horizontal">
??????????? <AlternatingRowStyle BackColor="#F7F7F7" />
??????????? <Columns>
??????????????? <asp:BoundField DataField="ScoreID" HeaderText="成績編號" ReadOnly="True"
??????????????????? SortExpression="ScoreID" />
??????????????? <asp:BoundField DataField="CourseID" HeaderText="課程編號"
??????????????????? SortExpression="CourseID" />
??????????????? <asp:BoundField DataField="StuScore" HeaderText="學(xué)生成績"
??????????????????? SortExpression="StuScore" />
??????????????? <asp:BoundField DataField="StuID" HeaderText="學(xué)生編號" SortExpression="StuID" />
??????????? </Columns>
??????????? <FooterStyle BackColor="#B5C7DE" ForeColor="#4A3C8C" />
??????????? <HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#F7F7F7" />
??????????? <PagerStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" HorizontalAlign="Right" />
??????????? <PagerTemplate>
??????????????? 當(dāng)前第:
?????????????? <%-- //((GridView)Container.NamingContainer)就是為了得到當(dāng)前的控件--%>
??????????????? <asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>
??????????????? 頁/共:
?????????????? <%-- //得到分頁頁面的總數(shù)--%>
??????????????? <asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label>
??????????????? 頁
???????????????? <%--//如果該分頁是首分頁,那么該連接就不會顯示了.同時對應(yīng)了自帶識別的命令參數(shù)CommandArgument--%>
??????????????? <asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page"
??????????????????? Visible='<%#((GridView)Container.NamingContainer).PageIndex != 0 %>'>首頁</asp:LinkButton>
??????????????? <asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev"
??????????????????? CommandName="Page" Visible='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>'>上一頁</asp:LinkButton>
?????????????? <%--//如果該分頁是尾頁,那么該連接就不會顯示了--%>
??????????????? <asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"
??????????????????? Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>下一頁</asp:LinkButton>
??????????????? <asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"
??????????????????? Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>尾頁</asp:LinkButton>
??????????????? 轉(zhuǎn)到第
??????????????? <asp:TextBox ID="txtNewPageIndex" runat="server" Width="20px" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' />頁
??????????????? <%--//這里將CommandArgument即使點(diǎn)擊該按鈕e.newIndex 值為3 --%>
??????????????? <asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="-2"
??????????????????? CommandName="Page" Text="GO" />
??????????? </PagerTemplate>
??????????? <RowStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" />
??????????? <SelectedRowStyle BackColor="#738A9C" Font-Bold="True" ForeColor="#F7F7F7" />
??????????? <SortedAscendingCellStyle BackColor="#F4F4FD" />
??????????? <SortedAscendingHeaderStyle BackColor="#5A4C9D" />
??????????? <SortedDescendingCellStyle BackColor="#D8D8F0" />
??????????? <SortedDescendingHeaderStyle BackColor="#3E3277" />
??????? </asp:GridView>

?

后臺代碼:

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) ???????

{ ???????????

GridView theGrid = sender as GridView; ???????????

int newPageIndex = 0; ???????????

if (e.NewPageIndex == -3) ???????????

{ ???????????????

//點(diǎn)擊了Go按鈕 ???????????????

TextBox txtNewPageIndex = null; ???????????????

//GridView較DataGrid提供了更多的API,獲取分頁塊可以使用BottomPagerRow 或者TopPagerRow,當(dāng)然還增加了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 ???????????

{ ???????????????

//點(diǎn)擊了其他的按鈕 ???????????????

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; ???????????

//重新綁定 ???????????

GridView1.DataBind();

??????? }
