Hi,
I have a server function that expects a string param and returns a
dataset.
[AjaxPro.AjaxMethod]
public DataSet getEvents(string cardno)
{
SqlConnection cn = new SqlConnection("Data
Source=euronet-server;initial catalog=euroMaster;user
id=sa;password=sa;");
string sql = "select
eventdate,eventdescription,devicedescription,devchilddescription from
eurevents where eventid in (616,617) and subitemno= "+
int.Parse(cardno) + " order by eventdate desc ";
SqlCommand cmd = new SqlCommand(sql);
cmd.Connection = cn;
cn.Open();
SqlDataAdapter adapter = new SqlDataAdapter(cmd);
DataSet dataSet = new DataSet();
adapter.Fill(dataSet);
cmd.Connection.Close();
return dataSet;
}
//Client side:
//(on click of the button)
function btn_onClick()
{
....
_Default.getEvents(strCard,_callbackEvents) //strvalue contains the
value
}
//Callback function
function _callbackEvents(evs)
{
var ds= new Ajax.Web.DataSet();
ds= evs.value;
if (ds!=null)
{
var cols = ds.Tables[0].Columns.length;
var rows = ds.Tables[0].Rows.length;
alert(cols + " cols and " + rows + " rows");
}
else
alert("No events found");
}
The server side is receiving the parameter and gets executed, but the
callback always gives a no events found message.
Please help.
