When trying to delete from a gridview asp.net I get Line 1: Incorrect syntax near 'nvarchar'.
Hi,
I'm pretty much a newb to the vb asp.net and I'm currently pulling my hair out trying to solve the following problem.
I have a grid view that displays data from a SQL view. I'm trying to get the gridview to delete a record in table the view is based on.
When I press the delete button I get "Line 1: Incorrect syntax near 'nvarchar'."
Can anyone offer any suggestions on how to resolve this?

As I don't want to have to select before deleting (ie pressing a select button first) how would I change the code so the delete button knows what record it's associated with?
