用存储过程实现分页，除了上一页，下一页，第一页，和末页外还要有go按钮，以及go到那里的文本框。
前台：
<asp:GridView ID="GridView1" runat="server"
onrowdatabound="GridView1_RowDataBound">
</asp:GridView>
<br />
<br />
<asp:Button ID="btnFirst" runat="server" onclick="btnFirst_Click" Text="|<" />
<asp:Button ID="btnPrev" runat="server" onclick="btnPrev_Click" Text="<" />
<asp:Button ID="btnNext" runat="server" onclick="btnNext_Click" Text=">" />
<asp:Button ID="btnLast" runat="server" onclick="btnLast_Click" Text=">|" />
<asp:Label ID="Label1" runat="server"></asp:Label>
<asp:TextBox ID="txtPageNumber" runat="server" Height="26px" Width="43px"></asp:TextBox>
<asp:CompareValidator ID="CompareValidator1" runat="server"
ControlToValidate="txtPageNumber" ErrorMessage="必须为整数！" ForeColor="#FF3300"
Operator="DataTypeCheck" Type="Integer" Display="Dynamic"></asp:CompareValidator>
<asp:RangeValidator ID="RangeValidator1" runat="server"
ControlToValidate="txtPageNumber" ErrorMessage="输入数据不合法！" ForeColor="Red"
MaximumValue='9' MinimumValue="1" Display="Dynamic"></asp:RangeValidator>
<asp:Button ID="btnGo" runat="server" Text="Go" onclick="btnGo_Click" />
<br />
<asp:HiddenField ID="HiddenField1" runat="server" />
<asp:HiddenField ID="HiddenField2" runat="server" />
