I have 3 pages, one to add a category, one to edit the category, and one to delete the category. The add and edit work fine. The delete is not working for some reason. I click the link on my site to delete it, and I'm just staring at the green bar in my browser taking a long time. The add and edit don't take long at all to perform their function. I'm thinking this is a connection string issue, but I don't see how it can be the case. It relies on web.config for it just like the other pages. Following is the delete page code behind and also delete cascade from the business logic area. After the page refreshes, I'm not getting any diagnostics or error messages which I have in the code. Doesn't this have to mean a db connection issue?

First of all, when using the GridView control with Delete enabled, when I delete a record is the event handler in the code behind file handled before the record is deleted or after? I need to obtain a counter value that I have set up in the record before it is deleted so that I can decrement all of the counter values that followed it. Is the best way to do this to open a connection in the Delete even handler and take care of it by code, or is there another way to access a column value from the GridView control that would simplify the process?

I have to delete record from the database and I am using the data list control to display the data. I have to delete the data from two table, that means I have to pass an id to a stored procedure which will delete the data from the database.
I am confused how can I do this? As I am not using the generic functionaliteis of the DataList Control and I don't want to use them. I have alos another choice to create a new page and pass the id through query string using hyperlink. But I don't want to do that?
