No, it's not working with getParams either.

Works for me. I:

1. dropped this into a stock SmartClient 5.6 Evaluation package

2. created a simple data file:

Code:

<List>
    <country>
       <RailRoadInvolved>1</RailRoadInvolved>
       <Yard>2</Yard>
    </country>
</List>

.. and set the initial dataURL to point to this file

3. used Fiddler to see the request generated when I press the "Process" button. I see the parameters:
"?RailRoadInvolved=1&Yard=2" added to the end of the dataURL as expected.

Aside from some problem in your .asp code, the only thing I can think of is that you may be expecting to see blank parameters for blank fields, eg "RailRoadInvolved=&Yard=&DateOfAccident="?

**markgoldin** · 5 May 2007, 15:30

I am checking Count property and it's 0. I am using same asp page with your product and with my test page. My asp code works fine in testing mode.
Give me another way to send data back. Maybe the alternative way will work.
Have you noticed that my code has two dynamic forms. That's not a problem, right?

**Isomorphic** · 5 May 2007, 15:57

Are you checking Request.QueryString.Count? As previously mentioned, if you switch to dataProtocol:"getParams", data arrives in the query string.

**markgoldin** · 5 May 2007, 16:05

No, I am checking it when I do post.
This is from Fiddler when I click on a button with saveData code:
QUERYSTRING ====
datarequest=xml
methodexecute=mProcessAccidentFileRequest

**Isomorphic** · 5 May 2007, 16:11

Again:

1. set dataProtocol:"getParams"
2. ensure there is data in at least one form field
3. press "Process" in your UI

On the server, Request.QueryString will have the data. Fiddler will show it under the QueryString tab as well as simply in the URL field of the "HTTP Sessions" grid.

**markgoldin** · 5 May 2007, 16:20

Ok, with getParams it works. Will check post again.

**markgoldin** · 5 May 2007, 16:24

Still when I use postParams I get zero for form's Count

**Isomorphic** · 5 May 2007, 17:07

Adding the following to your DataSource with dataProtocol:"postParams" may make Request.Form work:

Code:

    transformRequest : function (dsRequest) {
       dsRequest.contentType = "application/x-www-form-urlencoded; charset=UTF-8";
        return dsRequest.data;
    }

If not, we'd recommend proceeding with dataProtocol:"getParams" unless there's some reason that won't work for you.

**markgoldin** · 5 May 2007, 17:29

What do I need to add? New function or contentType property setting?

**Isomorphic** · 5 May 2007, 17:32

What was posted was the literal code to add.

Your modified DataSource definition should look like this:

Code:

isc.DataSource.create({
	ID:"countryDS",
	dataFormat:"xml",
        dataProtocol:"postParams",
        transformRequest : function (dsRequest) {
             dsRequest.contentType = "application/x-www-form-urlencoded; charset=UTF-8";
             return dsRequest.data;
        },
	dataURL:"accidents.asp?datarequest=xml&methodexecute=",
	recordXPath:"//country",
        fields:[
        {name:"countryCode", title:"Code"},
        {name:"countryName", title:"Country"},
        {name:"independence", title:"Nationhood", type:"date"},
        {name:"population", title:"Population", type:"integer"},
        {name:"gdp", title:"GDP", type:"float"}
    ]
 });

**markgoldin** · 5 May 2007, 17:47

Yes, that helped.
Can you briefly explain why?

**Isomorphic** · 5 May 2007, 18:43

It's not completely clear. Your server was ignoring form parameters that other servers will accept. An explicit charset setting in the content-type HTTP header was the only detectable difference in sample requests known to work vs the request SmartClient was sending, and that seems to correct the problem, so we've made it the new default.

**markgoldin** · 5 May 2007, 19:19

Dont know if it makes any difference but I am working with IE7 on Vista.

**Isomorphic** · 5 May 2007, 19:29

It doesn't, we test browser variations down to the granularity of what service packs are installed. This issue is specific to your server configuration, and although the cause is not completely clear, the next version of SmartClient will automatically use the workaround we just applied to your application (explicit contentType w/charset).
