I had a problem in web.config so I was told to remove
"xmlns ="http://schemas.microsoft.com/.NetConfiguration/v2.0"" so I removed it and now it is giving me errors upon deployment of the website. that it doesn't recognize the connection string.
What should I do?

I am doing an application and all the pages work fine.
I am using Infragistics UltraWebgrid control in the form, but it also works fine
in most pages.
The problem is that i am experiencing an error called "Invalid Procedure or argument " in runtime...
The Javascript file in project does not show any error and the line number is showing as 359...
There is no such line in Javascript file attached to the project..
The paging doesnot work because of this...

Hello friends..I got following error in as site..
The type or namespace name 'Dbprocess' could not be found (are you missing a using directive or an assembly reference?)
What is the procedure to add reference to your project..Is it necessary to upload dbprocess file in bin folder
|
|
|
|
|
This 'Dbprocess' class file is a part of your webproject or it is in seperate class library project?

The Dbprocess class file is put in DBLibrary.dll file and the reference is added to my project. Everything runs fine on local but gives error on server...What is the solution for this..
|
|
|
|
|
Ok I suppose that DBLibrary.dll is Compiled without including the DBProcess class file. To verify this --
Go to Visual Studio .NET command prompt and
Run this Command -- ILDASM
this will open the Intermediate Language Disassembler where you can see all the list of class files included in your DBLibrary.dll. In the list just check DBProcess class file is available or not. If not available then you will have open the DBLibrary class library project and Include the DBProcess class file, compile it, then put the latest build in your BIN folder and reference it.

Yes Sir You are right ..In The MSIL Disassembler no class file is found..But the class file is present in the DBLibrary project..Is it necessary to include class file in app_code folder...?

IF DBLibrary is a seperate class library project and Your DBProcess is a class file part of your DBLibrary then there is no need to include class file in app_code folder.
Amit.Jagtap wrote: Yes Sir You are right ..In The MSIL Disassembler no class file is found..
Did you Do this?

Also check in the ILDASM by opening the .dll file...
Make sure that class is available...

Is it necessary to publish a web site before uploading?

This question seems to be bit confusing...
As far as I know -- Uploading a site to a server is Publishing a website in a webserver.
Uploading (Publishing)

A file can be physical present in the location but may not be actually Included in the project. It has to be explicitly Included in you project (By anychance if it is excluded from the Project for any reason)
