The Good way:

1) Check if Session["id"] is not null.
2) Use Session["id"].GetType() to identify the name and whether it is castable to a DataSet.
3) Then do a cast.

Oh Sorry!

Session("ID").GetType()

I would update the original post also. Sorry again! Frown | :(

And thanks for the pointer. Smile | :)

Hi,

The below code works fine.The problem in your code is you are converting the session value into String and then casting to dataset so it is giving problem.
Actually ypu need to convert the session value directly to dataset.

Example:-

DataSet ds1;
ds1 =(DataSet)Session["id"];

The logic for converting the session to dataset is just by doing explicit type casting directly.

First Consider purpose of Dataset ....
DataSet Conatins table Why ? Table can have n number of columns why ?
I m sure it not for storing Session varaible directly into dataset
What you think ?

Is there any way of being able to open a database at the begging on a page, and close it at the end, where "#include file=..." have been used?

I'm currently having problem with declaration blocks etc? I've been told the global.asax however this hasn't worked

You would be better creating a DAL that maintains the connection information then for each database query have it open the connection, process the query, and then close the connection. You can then share the DAL across many pages which removes your need to store any kind of database information in the page classes.
