GridView如何实现无刷新分页？

 

拖这三控件，ScriptManager、UpdatePanel、GridView，其中GridView放在UpdatePanel里面。设置UpdatePanel的Triggers属性，分别绑定GridView的分页、删除、更新、编辑事件。OK。GridView怎么使用，我就不说了，不会的话去找找资料看看。如下：

<Triggers>
     <asp:AsyncPostBackTrigger ControlID="GridView1" EventName="PageIndexChanging" />
     <asp:AsyncPostBackTrigger ControlID="GridView1" EventName="RowDeleting" />
     <asp:AsyncPostBackTrigger ControlID="GridView1" EventName="RowUpdating" />
     <asp:AsyncPostBackTrigger ControlID="GridView1" EventName="RowEditing" />
</Triggers>

所有代码如下：

<asp:ScriptManager runat="server"   />

             <asp:UpdatePanel runat="server">

                 <ContentTemplate>

                     <asp:SqlDataSource runat="server" ConnectionString="<%$ ConnectionStrings:AjaxDbConnectionString %>"

                         SelectCommand="SELECT [id], [namer], [title], [content] FROM [userid]"

                         DeleteCommand="DELETE FROM userid WHERE id=@id"

                         UpdateCommand="UPDATE userid SET [namer]=@namer,[title]=@title,[content]=@content WHERE id=@id">

                         <DeleteParameters>

                             <asp:Parameter />

                         </DeleteParameters>

                         <UpdateParameters>

                             <asp:Parameter />

                             <asp:Parameter />

                             <asp:Parameter />

                         </UpdateParameters>

                         </asp:SqlDataSource>

                     <asp:GridView runat="server" AllowPaging="True" AutoGenerateColumns="False"

                         BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px"

                         CellPadding="3" DataKeyNames="id" DataSourceID="SqlDataSource1" PageSize="2">

                         <FooterStyle BackColor="White" ForeColor="#000066" />

                         <Columns>

                             <asp:BoundField DataField="id" HeaderText="id" InsertVisible="False" ReadOnly="True"

                                 SortExpression="id" />

                             <asp:BoundField DataField="namer" HeaderText="namer" SortExpression="namer" />

                             <asp:BoundField DataField="title" HeaderText="title" SortExpression="title" />

                             <asp:BoundField DataField="content" HeaderText="content" SortExpression="content" />

                             <asp:CommandField ShowDeleteButton="True" />

                             <asp:CommandField ShowEditButton="True" />

                         </Columns>

                         <RowStyle ForeColor="#000066" />

                         <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                         <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />

                         <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

                     </asp:GridView>

                 </ContentTemplate>

                 <Triggers>

                     <asp:AsyncPostBackTrigger ControlID="GridView1" EventName="PageIndexChanging" />

                     <asp:AsyncPostBackTrigger ControlID="GridView1" EventName="RowDeleting" />

                     <asp:AsyncPostBackTrigger ControlID="GridView1" EventName="RowUpdating" />

                     <asp:AsyncPostBackTrigger ControlID="GridView1" EventName="RowEditing" />

                 </Triggers>

             </asp:UpdatePanel>
