Did you copy this code from somewhere else? Common is somebody's namespace, it is not built-in to System. See previous comment on how to get FileName or find the Common namespace in your App.

I am adding some additional code to a C# 2010 web form application that I would like suggestions on how to accomplish the following:
1. I just created an additonal web form page to an existing application so the user can enter more information. I basically want the user to hit the 'back' button so they can return to the original web page and correct the values for up to 4 specific fields. There are two additional fields that the user is not allowed to change.
2. To point the user to the previous page, I do the command, "Response.Redirect("~/Att.aspx"); This works,
3. I want to be able to load all the information the user has entered already when the user returns to this web page. When the user returns to this webpage, the data has already been stored in two tables in the database.
4. Thus I am looking for your suggestion on how to accomplish this goal. I am thinking of the following options:
a. returning the user to the orginal web page in the state it was when they hit the 'next' button to go to the previous webpage. However I do not know how to proceed with this method.
b. Obtain the values from the database, or
c. use session variables. Thus can you tell me what you think the best method would be and examples of code of how you would accomplish this goal?

I would probably use session variables.
The details are all here: ASP.NET Session State Overview[^].
In the OnClick button method on the first page I would store the values in session variables and read them on the next form as required. When you navigate back to the first form repopulate appropriate fields with the session values. I'll leave it you to work out the particulars but the article link above should get you going.

I am already passing data to the second page as session varirables.
When I return to the first page, I would need to pass session variables from page two to page one. I would need to create new session variables for page 1, correct?

Hmm ... I was thinking of getting the data from the database.
My reason for this is that since you are adding functionality to an existing application, then let's assume that "Page 1" is a complete, working entity.
Now you add "Page 2" to the applicaiton and you build it in such a way that it stands on it's own and can store the additional fields. You just now provide a link which would bring them back to "Page 1" which should know nothing about "Page 2" nor the data that it stores.
Nice. Clean.
Now if the data between Page 1 & 2 are more intricately related, it may not be so easy to implement it this way. One thing you should protect against is that the user cannot navigate to Page 2 without completing Page 1.
Just a though. ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Under some circumstances, you might want to post one page to another page. For example, you might be creating a multi-page form that collects different information on each page. In that case, you can configure certain controls (those that implement the IButtonControl interface, such as the Button control) on the page to post to a different target page. This is referred to as cross-page posting. Cross-page posting provides some advantages over using the Transfer method to redirect to another page

Hi,
You can use TemplateField for doing the same.
Here is the example
<pre lang="VB">
<asp:TemplateField>
<ItemTemplate>
<table>
<tr>
<td>
<asp:Label ID="column1" runat="server" Text=""></asp:Label>
</td>
<td>
<asp:Label ID="column2" runat="server" Text=""></asp:Label>
</td>
<td>
<asp:Label ID="column3" runat="server" Text=""></asp:Label>
</td>
</tr>
<tr>
<td>
<%#Eval("field1")%>
</td>
<td>
<%#Eval("field2")%>
</td>
<td>
<%#Eval("field3")%>
</td>
</tr>
<tr>
<td>
<asp:Label ID="column4" runat="server" ForeColor="GrayText" Text=""></asp:Label>
</td>
<td>
<asp:Label ID="column5" runat="server" Text=""></asp:Label>
</td>
<td>
<asp:Label ID="column6" runat="server" Text=""></asp:Label>
</td>
</tr>
<tr>
<td>
<%#Eval("field4")%>
</td>
<td>
<%#Eval("field5")%>
</td>
<td>
<%#Eval("field6")%>
</td>
</tr>
</table>
</ItemTemplate>
</asp:TemplateField>

How do I dynamically populate controls on a MVC page?For example: I have a page to create questions. I have a drop down with questionType; and i have properties of questions which are specifc to question type; so on selecting specific question type, i want to show controls like textboxes and dropdowns to show properties relevant only to the selected option. E.g. If text type is selected, MaxTextlength textbox is shown. If singleselectradio is choosen a choice is shown to use standard options or create custom options, on selection of custom, something like user control is shown to add options . Bottomline: controls on a page, appear and disappear as per user selection in MVC. This can be easily achieved by loading dynamic user controls or show/hide panels in ASP.Net.

Hi
I need to download file that does not have extension. The file itself is a simple plain text file. I do this from code using WebClient object. I also cannot view this file in browser with the same error.The error was 404 - file not found.
After research I added mime type: .* as application/octet-stream on web server level. Also the file has these permissions:
NetworkService - full access, ASP.NET - full access. Rebooted machine after making changes.
Still the same issue.
Anybody can advise what else to look for?
Thanks a lot,
Roman

This does not mean that the file extension was missing or file could not be opened via selected application. It simply means that the path used to access the file downloaded is incorrect and there is no file at the given path.
Make sure you download it at a specified location, check file exists visually once downloaded then try to open it using correct filepath.

The file definitely exists. I have access to the server. If I add extension .txt to the file and to the url I can browse the file and download it.
What is puzzling me is that I was able to download files withou extension on one staging server with adding mime type .* as application/octet-stream . Then we built another paralel staging server for development where download fails. I check all settings I know on both servers and they are identical. I am guessing I am still missing some specific setting on this new development server.
Thanks

Above information is insufficient. You need to provide more details. Updating question with error would help.

Check Report Viewer versions present and used. Make sure they are same.
Also, check system EventViewer to see if any error logged there.
