后台：

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindStudent();
}
}

private void BindStudent()
{
string sql = "select * from student";
DataTable dt = SQLHelper.ExecuteDataTable(sql);
this.GridView2.DataSource = dt;
this.GridView2.DataBind();
}

protected void btnFirst_Click(object sender, EventArgs e)
{
this.GridView2.PageIndex = 0;
this.BindStudent();

}

protected void btnLast_Click(object sender, EventArgs e)
{
this.GridView2.PageIndex = this.GridView2.PageCount - 1;
this.BindStudent();
}

protected void btnPrev_Click(object sender, EventArgs e)
{
int index = this.GridView2.PageIndex;
if (index >= 1)
{
index--;
}
this.GridView2.PageIndex = index;
this.BindStudent();
}

protected void btnNext_Click(object sender, EventArgs e)
{
int index = this.GridView2.PageIndex;

this.GridView2.PageIndex = index;
this.BindStudent();
}

Label2.Text = "第" + (GridView2.PageIndex + 1).ToString() + "页，共" + GridView2.PageCount + "页";

}

Web.config:
<connectionStrings>
<add name="studentConnectionString" connectionString="Data Source=PC_THINK-THINK;Initial Catalog=student;Persist Security Info=True;User ID=sa;Password=111111"
providerName="System.Data.SqlClient" />
<add name="studentConnectionString2" connectionString="Data Source=PC_THINK-THINK;Initial Catalog=student;Persist Security Info=True;User ID=sa;Password=111111"
providerName="System.Data.SqlClient" />
</connectionStrings>

SQLHelper.cs:
public static DataTable ExecuteDataTable(string sql, params SqlParameter[] pms)
{
DataTable dt = new DataTable();
SqlDataAdapter adapter = new SqlDataAdapter(sql,connStr);
if (pms != null)
{
adapter.SelectCommand.Parameters.AddRange(pms);
}
adapter.Fill(dt);
return dt;
}

在这道题中用到了数据集 DataSet1.xsd
