you can always count the number of cells in a datagrid.
so you can iterate through them.

Hope this code will help
Let the datagrid be dg.

<br />
foreach(DataGridItem dgItem in dg.Items)<br />
	for(int i = 0; i < dg.Columns.Count; i++)<br />
	{<br />
		TableCell tc = dgItem.Cells[i];<br />
                //do the coding with table cell<br />
	}<br />

Well I wouldn't have got the job either!

I have never used more than one web.config file in an application.
never seen the need to.

Kind Regards,
Gary

We can have multiple web.config file for an application. If we divide our project into different folders, then each of the folders can have different web.config files apart from the web.config in the root.

When we access pages in a particular folder, it that folder contains a web.config file, setting there will have more priority that that of the root, ie., if you override a setting of the root web.config in the folder's web.config, the latter one will be used for the pages in that particular folder.

Yes We can have more than one web.config file. But each folder can have only web.config file. Lower level takes precedence over higher ones like web.cofig takes over machine.config. But you can configure higher web.config's setting in such a way that it cant be overriden also.

hi,
We can have more than one web.config files in the same project but we should give different names.

eg First.Config
Second.config

Whats the code like in your AddStudent Stored Procedure ?

If you're using a stored proc to do the add it would make sense to do a test in the stored proc if the user name exists, if it does then send a notification back to the application that the user name already exists and that the transaction could not be completed

Gary

well thats cool
i will send you the stored procedure code Smile | :)

thanks

CREATE PROCEDURE AddStudent
@Name varchar(20),
@Username varchar(20),
@Password varchar(20),
@SchoolID int,
@ParentID int,
@Address varchar(20),
@LevelID int

as
insert into users values (3,@Name,@Username,@Password,@SchoolID,@ParentID,@Address,@LevelID,NULL)
GO

CREATE PROCEDURE AddStudent
@Name varchar(20),
@Username varchar(20),
@Password varchar(20),
@SchoolID int,
@ParentID int,
@Address varchar(20),
@LevelID int

as

Declare @ExistUser varchar(20)
SELECT @ExistUser = Username from users where username = @username
IF(@ExistUser is Null)
Begin
insert into users values
(3,@Name,@Username,@Password,@SchoolID,@ParentID,@Address,@LevelID,NULL)
end

GO

This is something rough for you to use and give you an idea of what to do.
You'll have to elaborate a bit more on this

Kind Regards,

Well you can think about passing back a FAILED or SUCCEEDED values back,

wrap it up in a transaction, there are thousands of possibilities, but you'll find out about them more as you progress.
