doubts using YAHOO.util.Connect?

[franklt69]

I wonder is possible to fill responseText in object YAHOO.util.Connect from asp.net?

kind regards

Not sure what you're asking here. It doesn't matter what the server technology is. When a response is received from the server, YAHOO.util.Connect processes it and populates the response object with what comes back (text and/or xml). You can verify this by stepping thru the code in a debugger - it's very clean and easy to follow. Either your request works or it doesn'tm but processing flows thru Connect.handleTransactionResponse()

Thanks tryanDls, the doubt come from http://www.yui-ext.com/forum/viewtopic.php?t=3312

when I am using YAHOO.util.Connect I have two functions
sucess and failure


var hcallback={
success: saveSucess,
failure : responseFailure
};

YAHOO.util.Connect.asyncRequest('POST', "/Handler1.ashx", hcallback, xmlSearch)

the doubt is if YAHOO.util.Connect begin a transaction and in the server an exception is raise, then
YAHOO.util.Connect populates the response object with what comes back (text and/or xml) in asp.net is an complete html page for default, then in the client the function responseFailure is triggered but I can't show it in an alert,

but if I want send a message from the server (not complete html page) and not raise an exception then I have trouble because the function responseFailure isn't triggered, I mean the saveSucess function is triggered, I can parse the response in the saveSucess fuction and detect if is an error or not but I think is wrong this approach.

I would like to know if someone using asp.net show a customize error from the server in an alert message in client.

You seem to be asking the same question as you did in the other thread. Look at what Connect does to determine whether you have a good/bad response. You need pass a statuscode that indicates an error. The ASP.Net Response object has a property you can set to do this.

Thanks again TryanDls I know how check the status code in the client, and how from the server I can change the status code for instance if I set:

try
{
Stream requestStream = context.Request.InputStream;
using( StreamReader sr = new StreamReader(requestStream, System.Text.Encoding.UTF8))
{
dosomething(); //here I raise an exception
context.Response.Write(result);

}
}

catch (Exception e)
{
context.Response.Status = "14000";
}

but I don't know how from sever I can set a message that populate response.responseText of YAHOO.util.Connect, becouse in it always I get the complete html error.

a little example how set in the response.responseText the message that I want from asp.net is welcome.
