Why do I get the following server exception (500 response) when calling GetResponse() (HttpWebRequest) on a page with a WebDatePicker on it?

Hello FireStorm12,
Can you tell me what version and what build is the “WebDatePicker” control that you use in your application?
Also where in your code (in what event) do you call “GetResponse()” method?
If you can send me a simple example or code snippet that can allow me to reproduce this behavior it will be very useful in quickly identifying the cause of this exception.
I am looking forward to hearing from you.
Infragistics4.Web.v11.1, Version=11.1.20111.1006
I call GetResonse() from a separate WinForms application that I use to poll various web applications to determine their status. The code is essentially this:
// Create a HttpWebRequest to check for response
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://" + url);
webRequest.Timeout = Constants.ResponseTimout;
webRequest.Credentials = CredentialCache.DefaultCredentials;
NetworkCredential nc = CredentialCache.DefaultNetworkCredentials;
WebProxy proxy = new WebProxy("http://" + url);
proxy.Credentials = nc;
webRequest.Proxy = proxy;
try
{
using(HttpWebResponse resp = (HttpWebResponse)webRequest.GetResponse())
if(resp.StatusCode == HttpStatusCode.OK)
return true;
else
return false;
}
catch(Exception e2)
LogError(string.Format("*** ERROR CHECKING APP FOR RESPONSE ***{0}{1}{0}",
CRLF, e2.Message), e2);
Can you answer the following questions:
Do you have other controls on this page?
If you remove the "WebDatePicker" control does this exception still occur or it is not present?
Are you able to load other pages with this code and does the page tested can be opened with the browser?
Does the page uploaded on remote Server or tested on Development Server?
I am waiting for your response.
1) There are two WebDatePickers, a couple of standard buttons and text boxes, and a Crystal Reports viewer.
2) I have not tried removing the WebDatePickers.
3) The code is part of a home-grown application monitor that we have been using for years. This is the only application with the problem.
4) The page opens and functions normally in a web browser.
