AJAX分页的代码(后台asp.net)

public partial class jQueryPaging : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Int32 pageIndex=Int32.MinValue;
Int32 pageSize=Int32.MinValue;
String name=String.Empty;
JavaScriptSerializer jss=new JavaScriptSerializer();
if(Request["Name"]!=null)
{
name=Request["Name"].ToString();
if (Request["PageIndex"] != null)
{
pageIndex = Int32.Parse(Request["PageIndex"].ToString());
pageSize = Request["PageSize"] != null ? Int32.Parse(Request["PageSize"].ToString()) : 10;
IList customersLists = new List();
Customer c = null;
DataSet ds= LookDataFromDB(name,pageIndex,pageSize);
foreach (DataRow row in ds.Tables[0].Rows)
{
c = new Customer();
c.CustomerID = row["CustomerID"].ToString();
c.CompanyName = row["CompanyName"].ToString();
c.ContactName = row["ContactName"].ToString();
c.ContactTitle = row["ContactTitle"].ToString();
c.Address = row["Address"].ToString();
c.City = row["City"].ToString();
customersLists.Add(c);
}
if (customersLists.Count>0)
{
Response.Write("{\"Count\":"+ds.Tables[1].Rows[0][0]+",\"Customers\":"+jss.Serialize(customersLists)+"}");
Response.End();
}
}
}
}
private DataSet LookDataFromDB(string name, int pageIndex, int pageSize)
{
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString);
conn.Open();
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "SearchCustomerByName";
cmd.Parameters.Add(new SqlParameter("@name",name));
cmd.Parameters.Add(new SqlParameter("@pageIndex",pageIndex));
cmd.Parameters.Add(new SqlParameter("@pageSize", pageSize));
SqlDataAdapter dataAdapter = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
try
{
dataAdapter.Fill(ds);
}
catch (Exception)
{
}
finally
{
if (dataAdapter != null)
{
dataAdapter.Dispose();
}
if (cmd != null)
{
cmd.Dispose();
}
if (conn != null)
{
conn.Dispose();
}
}
return ds;
}
}

public class Customer
{
public String CustomerID { get; set; }
public String CompanyName { get; set; }
public String ContactName { get;set;}
public String ContactTitle { get; set; }
public String Address { get; set; }
public String City { get; set; }
}
SearchCustomerByName 存储过程的代码如下：
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
Create PROCEDURE SearchCustomerByName
@name nvarchar(30),
@pageIndex int,
@pageSize int
AS
BEGIN
SET NOCOUNT ON;
select t.CustomerID,t.CompanyName,t.ContactName,t.ContactTitle,t.Address,t.City from
(
select Row_Number() over (order by CustomerID) AS RowNum,* from Customers where ContactName like '%'+@name+'%'
) t
where t.RowNum between @pageIndex*10+1 and (@pageIndex+1)*10
select count(*) from Customers
where ContactName like '%'+@name+'%'
END
GO
