我想实现当在文件框中输入信息的时候动态从数据库里过滤的功能．
我装了:AjaxControlToolkit ASPAJAXExtSetup.msi ASPAJAXCTP.msi
是按照：http://blog.csdn.net/kRiSnI/archive/2007/04/18/1569125.aspx
的方法做的．．按它的意思应该可以实现我需要的结果的．
Webservice.cs代码如下：
[WebMethod]
public string[] GetTextString(string prefixText, int count)
{
DataTable dt = Test.ReportView();
DataView dv = new DataView(dt);
dv.RowFilter = "编码 like '% " + prefixText + "% ' ";
DataTable dtnew = dv.ToTable();
List <string> list = new List <string> ();
foreach (DataRow dr in dtnew.Rows)
{
list.Add(dr[ "编码 "].ToString()+ "| "+dr[ "名称 "].ToString());
}
return list.ToArray();
}

在web.config里加上这个试试

如果不是新建的ajax项目，而是引用dll的话，需要配置Web.config
