You'll have to provide a bit more detail than this. What do you mean "can't delete"? Do you get an exception? Does it just not work?

Must declare the scalar variable "@ID".

this was exception...
what else do you required.. ??

You will have to specify an SqlParameter for ID.

Solution 1

@ID is never declared or set to any value. Where should @ID be getting its value?
