1 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。另外还要在Lable显示“当前x页，一共y页”。注意验证控件的使用和 链接存储过程的内容。
前台
<div>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" >
<Columns>

<asp:BoundField DataField="age" HeaderText="年龄" />
</Columns>
</asp:GridView>
<asp:Button ID="btnFirst" runat="server" Text="|<"
Xonclick="btnFirst_Click" />
<asp:Button ID="btnPrev" runat="server" Text="<" Xonclick="btnPrev_Click" />
<asp:Button ID="btnNext" runat="server" Text=">" Xonclick="btnNext_Click" />
<asp:Button ID="btnLast" runat="server" Text=">|" Xonclick="btnLast_Click" />
<asp:Label ID="Label1" runat="server"></asp:Label>

<asp:HiddenField ID="HiddenField2" runat="server" />
<br />
<asp:TextBox ID="TextBox1" runat="server" Visible="False"></asp:TextBox>
<asp:TextBox ID="TextBox2" runat="server" Visible="False"></asp:TextBox>
</div>
后台
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindStudent(1);
}
}
private void BindStudent(int index)
{
string conStr = ConfigurationManager.ConnectionStrings["conStr"].ConnectionString;
using (SqlConnection conn = new SqlConnection(conStr))
{
conn.Open();
using (SqlCommand cmd = conn.CreateCommand())
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "sp_Student_Select_by_Page_rowNumber";
cmd.Parameters.AddWithValue("@pageSize", 3);
cmd.Parameters.AddWithValue("@pageIndex", index);
cmd.Parameters.Add("@pageCount", System.Data.SqlDbType.Int).Direction = ParameterDirection.Output;
SqlDataAdapter adapter = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
adapter.Fill(dt);
GridView1.DataSource = dt;
GridView1.DataBind();
string pageCount = cmd.Parameters["@pageCount"].Value.ToString();
Label1.Text = "当前第"+index.ToString()+"页共"+pageCount+"页";
HiddenField1.Value = index.ToString();
HiddenField2.Value = pageCount;

{

}

2.实现手动排序，不适用gridview中的分页。
前台
<div>
<asp:GridView ID="GridView1" runat="server" AllowSorting="True"
AutoGenerateColumns="False" Xonsorting="GridView1_Sorting">
<Columns>
<asp:BoundField DataField="sid" HeaderText="编号" SortExpression="sid desc" />
<asp:BoundField DataField="sname" HeaderText="姓名" SortExpression="sname" />
<asp:BoundField DataField="age" HeaderText="年龄" SortExpression="age asc" />
</Columns>
</asp:GridView>
</div>
后台
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bindStudent("sid");
}
}
private void bindStudent(string sort)
{
string constr = ConfigurationManager.ConnectionStrings["conStr"].ConnectionString;
using (SqlConnection con = new SqlConnection(constr))
{
using (SqlCommand cmd = con.CreateCommand())
{
string sql = "select * from student order by " + sort;//有漏洞，和使用参数的方式解决。
cmd.CommandText = sql;
SqlDataAdapter adapter = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
adapter.Fill(dt);
this.GridView1.DataSource = dt;
}
}
this.DataBind();
}
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
bindStudent(e.SortExpression);
}
3.参考代码实现全选、全不选（选作。提示使用模板页，其中加入checkbox控件）

foreach (GridViewRow row in this.GridView1.Rows)
