Guys, I've just created an auto post-back user control. this control used to work really good but suddenly it threw an exception on post-back saying :
Message: Sys.ArgumentNullException: Value cannot be null.
Parameter name: postBackElement
this exception was thrown in the auto-generated function:
Sys.WebForms.BeginRequestEventArgs = function Sys$WebForms$BeginRequestEventArgs(request, postBackElement) {
var e = Function._validateParams(arguments, [
{name: "request", type: Sys.Net.WebRequest},
{name: "postBackElement", domElement: true}
]);
if (e) throw e;
Sys.WebForms.BeginRequestEventArgs.initializeBase(this);
this._request = request;
this._postBackElement = postBackElement;
}
Please help me.
I used
onchange="__doPostBack('ctl00$ContentPlaceHolder1$ddlStartDate','')"
where ctl00$ContentPlaceHolder1$ddlStartDate is the name of my control.

if(Context.Request.ServerVariables["HTTP_VIA"]!=null)
{
ip=Context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
}
else
{
ip=Context.Request.ServerVariables["REMOTE_ADDR"].ToString();
}
Note:
1. Some time Proxy Servers is not sending real client IP so in that case there is no way to find the client IP.
2. I am not sure we can find client computer name without any extra effort with only Asp.Net.
Thanks

What is not working ? Are you getting any error ? What code you have written ?

If you write out the email column in the following format
<a href="mailto:user@domain.com">Send email</a>
it will send the email using the default email client. But, that is not recommended way of doing it. For starters, since the email is exposed, it can be harvested by bots easily. Instead handle it at the back-end or use some email address obfuscation javascript code.

have you tried mailto:address?

Hi All,
I am writing documents for my asp.net web application, web service and windows service integration with other web service application. I want to know the differences between Proof of Concepts, Technical Specifications and other documents which are mostly or likely related to the developer some times.
The other thing is that a company approached me for some sort of work, it has explained me some thing about whats thier issue and what they want then I did some research and given them a POC document with different approaches to resolve those issues. Did I do correct here by naming my document as POC? Is it right to give the approaches in the POC?
After that they have accepted for one approach, then I again did some research and given them architecture of the application and how it looks and data flow diagrams etc and system harware and software requirements. But the system is not implemented yet. It should be implemented yet but have given the complete architecture how it looks, data flow diagrams every thing.
Should I name this document as POC with different version only or Technical specifications document. What kind of document it is now?
Please give me any sort of help or any links are ok for me.
Thanks and your help would be appreciated.
Thanks & Regards,

You need to do some reading. Start here, How to get an answer to your question[^] and look at item #3. "Documents" is certainly brief but no where near descriptive enough.
A Proof of Concept is not a document. In the software world it is a small application that demonstrates the concept being proposed.
Quite frankly if you don't know the meaning and purpose of these documents I would question your entire design/architecture. The company who hired you will likely get exactly what they paid for and after it has failed, miserably most likely, someone like me will end up correcting it for a healthy profit.

Hi,
I am researching for it but finding the difference and when should I give which document.
If there is any document or white paper which descrubes all these steps when to do what document, am not finding any where.
If you could really help me that would be appreciated.
Thanks.
Thanks & Regards,

Not clear what do you want to meant. Do you want your checkbox to main to postback details when checked or unchecked ? While creating the checkbox did you set CheckBox.Autopostback = "true" and in which events you have created the checkboxes ?

Make sure you have set 'EnableViewState=True' for the checkbox control as well as it's container. Since, you need to re-create your checkbox during postback it might be getting reset to nothing and hence the value & text.

Sandeep Mewara wrote: Make sure you have set 'EnableViewState=True' for the checkbox control as well as it's container
Sandeep, For Checkbox EnableViewState property works in some different way. CheckBoxControl Implement from IPostBackDataHandler . This value is not read from view state but from Postback from and this is true for those control which implements the IPostBackEventHandler. Because in Page Lifecyle, before Page_Load we have LoadViewState() and LoadPostbackData(). So, though you disable the viewstate for Checkbox, It will load the data in LoadPostbackData() method. This is same for a text box control as well.

Good Explanation. Every input control like checkbox, radio, textbox, hidden etc... loads its data from the form collection during LoadPostbackData() event.ASP.NET implements IPostBackDataHandler on every input control and it actually uses form collection to update the control in the LoadPostbackData() event.

Just a minor change required here AJ. The value is read from the ViewState but overridden in the LoadPostbackData() method of the page life cycle for the controls which implement IPostBackDataHandler.

I'm not much of a web developer..
Anyway today I had to reinstall my machine and couldn't access my WCF services from Silverlight because I needed a policyaccess.xml file in my (local host) wwwroot!
So.. I made sure IIS was running and copied the file there.
But the thing is IIS doesn't seem to run!
Anytime I access a missing file I have 404 error, ok, but anytime I try to access an existing file of whatever format (html, png, xml, you name it!) I get the same blank / white HTML page!?!?
Why is that? How can I browse me www root!?!
I browse all apparently relevant property in IIS Management console, but can't fix it!
A train station is where the train stops. A bus station is where the bus stops. On my desk, I have a work station....

Which version of IIS are you using ? Did you check Application Pool is running or Stopped ?
You may check Eventviewer to get the details of logging from IIS.
If, everything is fine, then the next thing you need to check is how you are hosting the files.
Let me know, Hope I may help you in this case.

sometimes, restarting IIS solves the problem.
