今天閑著無事,在C#2.0下用Ajax寫了一個無重新整理快速分頁例子,時間倉促,不足之處請大家指出:首先把AjaxPro.dll檔案添加到引用中,可以到http://www.schwarz-interactive.de/下載 根據你的.net 版本來選擇不同的DLL檔案.default.aspx.cs:public partial class _Default : System.Web.UI.Page
{
string connectString = "";//定義自已的串連串
protected void Page_Load(object sender, EventArgs e)
{
AjaxPro.Utility.RegisterTypeForAjax(typeof(_Default));
} [AjaxPro.AjaxMethod]
public DataTable GetDataTable()
{
SqlDataAdapter ad = new SqlDataAdapter("select * from tableName", connectString);
DataSet ds = new DataSet();
ad.Fill(ds);
int num = ds.Tables[0].Rows.Count;
return ds.Tables[0];
