Hi,
well as the error is already saying, you have to disable event validation or register the events for validation. This is a security feature to disallow illegal postbacks. I'm guessing you are using some kind of dynamic controls within your app.
To solve the problem you can:
1.) Open the web.config and add the the tag <pages enableEventValidation="false"/>
2.) or open the page (in VS) causing the error, switch to HTML Layout, browse to the first line and set EnableEventValidation="false" (or add if it is not there)
3.) or use the ClientScriptManager, but I never did this before...
4.) or don't use dynamically created controls 
Regards
Sebastian

Hello,
I am working on a Data Centric Web Application of Creating Inventory Application.
I have decided using ModalPopupExtender for Adding and Modifying records.
eg. I have a Company master, i first display the List of records in Gridview and then if user clicks on Add or Edit Button, will display the modal popup with a Form for entering data.
I have succeeded in Creating this and everything works fine, the modal popup is displayed on clicking on Modify or Add button in the gridview, but the problem is about displaying data in controls of the modal popup.
When the page loads, and when i click on Add button for first time, The popup displays properly with blank controls,
Also When i click on Modify, it properly fills the controls with proper data of the selected record from the Gridview,
The problem begins here, now when i again Click on Add button, it does not display blank controls but display the same data which i selected in Modify.
Can anyone please tell me why this happens, after clicking on Modify Button , Add button does not work, but again clicking on Modify properly displays another record from the gridview.
I have placed a Gridview in UpdatePanel1 and The form for dataentry in another updatepanel2 inside a Panel.
What i am doing is, on click Add button I am clearing all controls on the form and doing UpdatePanel2.Update before displaying The Modal. But this does not work, whereas in Modify button i do the same thing just that i fill the controls this time with data selected and i again do UpdatePanel2.update and this works perfectly fine.
Could Anyone please suggest me something on this topic.
Hope I have clearly specified my Query.
Waiting for a reply, Thanks In Advance.

It almost sounds like you are talking about Java or C# or something. You sure you are in the right place?
Don't let my name fool you. That's my job.

Just zip your file and upload through FTP.
after you upload, extract and make that a virtual directory from IIS.
Simple... ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)
Now dont ask me that you want to host your website through FTP. means it would have a FTP protocol......

Most FTP clients (CuteFtp, FileZilla, etc) have a fairly nice GUI that allows you to connect to the target server, select the target directory, view and select the files and folders on the local computer that you'd like to move to the target. They're a lot easier to use than the straight FTP client provided by Windows.
When you open the ftp program you should have two panes open; one is your local computer, the other empty. You'll find a place to enter the name of the target computer (or domain) and a usename/password for ftp access. When you connect the blank pane will display the home directory of the target and its contents. In the local pane, navigate to the root directory of your local website and select all the files and folders you want to move. Click the transfer or upload button and they'll be copied to the target folder. If you're not sure which items are required, select all of them from your local website root folder; it won't hurt to copy unneeded files.
It's usually fairly straightforward, though it's not always easy to figure out which direction the transfer will go. Some programmers are awfully vague with their instructions and button labels. If you have any questions, the hosting company probably has a step-by-step help procedure in the FAQ section of their website. If that isn't helpful, try their tech support; that's part of what you're paying for.

Hello all,
In my company we currently have a web page that semi-works: I mean that it gives us some contacts and that is very positive, but the guys/girls that made it made it really bad. We have improved the way it works behind the scenes just keeping the SEO tasks they made, but as now some links have changed, I wanted to know how to switch from the old site to the new one without loosing any possibility of loosing a customer...
I'm worried about this: If I delete the old page I will loose all the current indexed google pages suddenly and I'll have to wait for the new ones to be indexed. Meanwhile the new ones are not indexed, I'll probably loose some possible contacts.
How would you proceed?
I can think of:
A1- Upload the new links and change the main page.
A2- Maintain the old links but change the content in order to redirect to the new pages.
B1- Upload the new set of links (the entire site) to a new folder.
B2- Keep google and others to link to the old pages and make it point to the new ones.
B3- Delete the old links once I've seen that google have the new ones indexed.
C1- your option here...
Thank you in advance for your time and help.

If you have moved content the use a 301 redirect. The Search engines will pick them up quickly and your users will have a smooth transition.
...aaaand I'm going to move this to the web development forum

Hi All,
In an application, how do I create tables in a database to store Profiles, Roles, User, User in Roles, Memberships ...
Does ASP. Net create them automatically or are they created by the user. How do I ensure that when I use 'Website -> ASP.NET Configuration' option
of Visual Studio, updates made using Security, Application Configuration and Provide Configuration reisde in this database?
How does the mapping work?
Thanks,

Hi NetQuestions,
It all depends on what you are trying to achieve. A seperate database is over the top and not needed.
Maybe needed if you have a local database and a remote database, but to be honest I would still hold the user credentials on both anyway. More databases equal potentially more maintenance / overhead, more chance to get hacked and more connections strings / threads.

I have a forms project that will allow user to connect to a local database or a webservice hosting the data.
So the flow goes something like:
App builds request object (SearchCriteria) defined in a class library. Local data access layer and webservice both use the SearchCriteria object to run queries, and return a Results object (also defined in the class library).
So my desktop app has a ClassLibrary project which defines the Request and Results classes. This dll is imported into the Webservice solution.
I’ve developed an interface to define the contracts between the desktop app and the data provider (either the local DAL or the Webservice).
public interface IDataAccess
{
DataTable GetCompanyMatches(SearchCriteria searchCriteria, out Results results);
…
}
One edit to the Reference.cs file tells the compiler that my Webservice implements the interface.
internal interface WSSoap : ITPDataAccess
The problem is that when the Webservice returns the Results object the desktop app sees the type as Webservice.Results instead of ClassLibrary.Results, so the Webservice does not implement IDataAccess (even though I specify, in the webservice, webservice inherits from/implements IDataAccess.
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class WebService : ITPDataAccess
{…..}
Is there a way to tell the WS to not put the ClassLibrary classes into the Webservice namespace? Is there some way on the app side to use the locally defined classes when interacting with the webservice?
Basically how do i tell the compiler that they are the same thing, without rewriting the Reference.cs file??

Hello,
I have problem here, i know how to configure IIS compression but the problem is for the first time client request, IIS checks whether the file requested is compressed and if not it sends uncompressed file and then start compressing it in background thread and stores it in cache folder for subsequent calls.
Is there any way , some script or some configuration, where i can make iis to compress all the files before-hand and keep ready for calls (right from first call)?
Thanks.

Well, from your initial description I would say it should help!
Please be more specific when you say 'This does not help'.
The application calls specific pages which would in-turn cache the pages in IIS. This would then make them readily available to everyone else. So how does this not help?

A bit of a general FLV question:
About a week ago a few of my FLV players on various sites stopped showing up. I have searched google and found others with the same problem but no solutions. I was wondering if anyone else has come accross this problem or a solution (working FLV player):
Here's the details:
- I have two different progressive download FLV players but both are embedded using javascript and object tags (DreamWeaver CS3s insert->Media->Flash Video). I have both players on several web servers
- The video players used to work on every site (multiple servers, hosts & OS) - Now only some servers fail.
- The FLVs work on both Linux and Windows Servers but also fail on Windows and Linux Servers - so it's not a OS specific bug.
- They were throwing a "function is undefined" error (it was clearly defined - "AC_RunActiveContent.js" - for those who know). Now they aren't throwing any errors at all - the code hasn't been changed. Is this an adobe "codebase" thing?
- It's player works an fails on different sites using various versions player - but the same sites are always the ones that fail (no matter what the flash player version is)
So... It doesn't seem to be a coding problem... It's not an OS Specific problem... It's not just one web host... Er.
