Ajax.NET Pro has built-in exception Handling, it passes the exception to
the client.
[AjaxPro.AjaxMethod]
public DataSet GetDS()
{
DataSet ds = new DataSet();
//generate error
...
return ds
}
// Client
function getDS()
{
this._Default.GetDS(getDS_callback1);
}
function getDS_callback1(res)
{
if (res.error != null)
{
alert(res.error.Message);
} else
{
var dataSet = res.value;
}
}
If you want to return more than one Information you can build an little
Class for that.
// Server
public class DataSetResult
{
private string error;
public string Error
{
get { return error;}
set { error = value;}
}
private DataSet dataSet;
public DataSet DataSet
{
get { return dataSet;}
set { dataSet = value;}
}
}
[AjaxPro.AjaxMethod]
public DataSetResult GetDS()
{
DataSetResut dsr = new DataSetResult();
try
{
DataSet ds = new DataSet();
//generate error
dsr.DataSet = ds;
}
catch (Exception e)
{
dsr.Error = e.ToString();
dsr.DataSet = new DataSet();
}
return dsr;
}
// Client
function getDS()
{
this._Default.GetDS(getDS_callback1);
}
function getDS_callback1(res)
{
if (res.error != null)
{
alert(res.error.Message);
} else
{
var dataSet = res.value.DataSet
var errorMessage = res.value.Error;
}
}
