RadCombox of Q1 2009, has problem with postback

I defined, 2 comboxes.
Combox1 is defined with selectIndexchanges: this will populate data for combox2.
That's work fine, unless I define a button with click_event. Once I click the button, the selectIndexChanged of Combox1 is also called. Not sure I did something or it is naturally new bug of Ajax Q1 2009? I did trying dropdownlist, it works fine. Could you give some suggestion?

Cheers,

Duy

HTTP POST with binary data in .NET

Hi

From VB.NET I want to simulate the POST request of the following HTML form

<html>   

<title>HTTP Post Testing</title>   

<body>   

<form action=http://www.example.com/postdata   

enctype="multipart/form-data" method="post" name="testform">   

<input id="user_login" name="user[login]" size="30" type="hidden"   

value="user01" />   

<input id="user_password" name="user[password]" size="30"   

type="hidden" value="123456" />   

               <table>   

                       <tr>   

                               <td>File:</td>   

                               <td><input id="file" name="file"   

type="file" /></td>   

                       </tr>   

                       <tr>   

                               <td colspan="2"><input name="commit"   

type="submit" value="Upload" name="upload"/></td>   

                       </tr>   

               </table>   

       </form>   

</body>   

</html>

The target URL would return "OK" for successful upload and empty otherwise.

My code to generate the POST request is as followed:

        Try 

            Dim request As HttpWebRequest = CType(WebRequest.Create(Me.txtURL.Text), HttpWebRequest) 'this textbox contains the target URL of the request  

            ' Set the Method property of the request to POST.  

            request.Method = "POST" 

            request.Accept = "*/*" 

            request.UserAgent = "curl/7.16.3" 

            request.ProtocolVersion = HttpVersion.Version11  

            request.Referer = "http://www.mydomain.com/" 

            request.SendChunked = True 

            System.Net.ServicePointManager.Expect100Continue = False 

            ' Create POST data and convert it to a byte array.  

            Dim postData As String = "" 

            postData += Boundary + Chr(13) + Chr(10) + "Content-Disposition: form-data; name=""user[login]""" + Chr(13) + Chr(10) + Chr(13) + Chr(10)  

            postData += "gape" + Chr(13) + Chr(10)  

            postData += Boundary + Chr(13) + Chr(10) + "Content-Disposition: form-data; name=""user[password]""" + Chr(13) + Chr(10) + Chr(13) + Chr(10)  

            postData += "telipoint8" + Chr(13) + Chr(10)  

            postData += Boundary + Chr(13) + Chr(10) + "Content-Disposition: form-data; name=""file""; filename=""helpcurl.txt""" + Chr(13) + Chr(10)  

            postData += "Content-Type: text/plain" + Chr(13) + Chr(10) + Chr(13) + Chr(10)  

            postData += "fdfgfggfbfgggggggggggggggg" + Chr(13) + Chr(10) + Boundary + "--" + Chr(13) + Chr(10)  

            Dim encoding As New System.Text.ASCIIEncoding()  

            Dim byteArray As Byte() = encoding.GetBytes(postData)  

            ' Set the ContentType property of the WebRequest.  

            'request.ContentType = "application/x-www-form-urlencoded"  

            request.ContentType = "multipart/form-data; boundary=" + Me.Boundary + vbCrLf + vbCrLf  

            ' Set the ContentLength property of the WebRequest.  

            request.ContentLength = byteArray.Length  

            ' Get the request stream.  

            Dim dataStream As Stream = request.GetRequestStream()  

            ' Write the data to the request stream.  

            dataStream.Write(byteArray, 0, byteArray.Length)  

            ' Close the Stream object.  

            dataStream.Close()  

            ' Get the response.  

            Dim response As WebResponse = request.GetResponse()  

            ' Display the status.  

            MsgBox(CType(response, HttpWebResponse).StatusDescription, MsgBoxStyle.Information, "Response Code")  

            ' Get the stream containing content returned by the server.  

            dataStream = response.GetResponseStream()  

            ' Open the stream using a StreamReader for easy access.  

            Dim reader As New StreamReader(dataStream)  

            ' Read the content.  

            Dim responseFromServer As String = reader.ReadToEnd()  

            ' Display the content.  

            txtResponse.Text = responseFromServer 'this textbox shows the response from the server  

            ' Clean up the streams.  

            reader.Close()  

            dataStream.Close()  

            response.Close()  

        Catch Ex As Exception  

            MsgBox(Ex.Message, MsgBoxStyle.Exclamation, "Error Encountered")  

        End Try

Here I tried to simulate the upload of a text file. When I tried this code the server alays return 404 (Resource not Found) even though the URL is correct. When the ContentType is changed to "application/x-www-form-urlencoded", i.e. no file upload but only transfer normal text fields, the server seems to accept the request and returns empty (unsucessful upload), which is correct. When I tried the above code (with content-type=multipart-formdata) against an ASP script put on my locahost:

<%  

test1 = Request.Form("user[login]")  

test2 = Request.Form("user[password]")  

Response.Write(test1 + "<br>" + test2)  

%>

my script returns empty strings, which means the POST request generated by my VB code is malformed. But I cannot see what's wrong. I have compared it to the output of the following curl command

curl -F user[login]=user01 -F user[password]=123456 -F
file=@myfile.txt http://www.readysnap.com/print/mup and everything is exactly the same.

Can anyone suggest what's wrong? Thanks. :)
