定时刷新DataGrid
我用AjaxPro,后台代码
[AjaxPro.AjaxMethod]
private   string   ShowData()
{
string   sql= "select   *   from   "+TableName+(sefileid!=0? "   where   SEFile_ID= "+sefileid: " ");

DataTable   dt=db.OpenTable(sql);
dgData.DataSource=dt;
dgData.DataBind();

System.Text.StringBuilder   sb=new   System.Text.StringBuilder();
System.IO.StringWriter   sw=new   System.IO.StringWriter(sb);
System.Web.UI.HtmlTextWriter   htw=new   HtmlTextWriter(sw);

dgData.RenderControl(htw);
string   s=sb.ToString();
return   s;

前台代码
function   Call_Show()
{
var   cc=document.getElementById( "dgData ");
cc.innerHTML=SEFile.ShowData().value;
}
function   Call_Server()
{
SEFile_ShowData();
Call_Show();
}

我怎么定时刷新DataGrid??


我用window.onload=setInterval( "Call_Server() ",1000);

setTimtOut都不行     提示网页有错误??

该怎么解决

我也是看ajax实战，看完后有段时间没用ajaxpro了，你的前台代码cc.innerHTML=SEFile.ShowData().value;我记得ajaxpro不是这样掉用吧，SEFile.ShowData(Call_Show_callback);然后再写一个Call_Show_callback(res){cc.innerHTML=res.value;},还有，以前用的时候听人说ajaxpro中类似于cc.innerHTML=SEFile.ShowData()这样的调用不是真正的异步，听说而已。提示未定义你是否注册了SEFile，同时好像在2003中要写成 你的项目名.SEFile.ShowData ，说错务怪啊
