AllowPaging="True" AllowSorting="True" PageSize="2" AutoGenerateColumns="False" OnPageIndexChanging="GridView1_PageIndexChanging" OnSorting="GridView1_Sorting">
<Columns>
<asp:BoundField DataField="TestID" HeaderText="TestID" SortExpression="TestID" />
<asp:BoundField DataField="TestUser" HeaderText="TestUser" SortExpression="TestUser" />
<asp:BoundField DataField="TestTime" HeaderText="TestTime" SortExpression="TestTime" />
</Columns>

cs部分示例代码

//绑定GridView

#region 得到绑定GridView的DataTable

#endregion
#region 分页

#region 排序
