2) Detach the event hander before the unwanted event triggers and re-attach after.
There are two ways to manage unwanted execution of event handlers. Data Grid View Cell Validating Event Args' does not contain a constructor that takes '1' arguments" what is the solution for this???????

However, it's a pain in the behind to use because you can't create a strongly-typed variable to store a genuine value or null. Just a suggestion, but what I normally do is this: While reader. Add(New DDLItem( _ CType(reader("rid"), Integer), _ CType(reader("Item_Status"), String), _ CType(reader("Text_Show"), String), _ CType( IIf(Is DBNull(reader("Text_Use")), "", reader("Text_Use")) , String), _ CType(reader("Text_System Only"), String), _ CType(reader("Parent_rid"), Integer))) End While VB.
However, you are still stuck with large chunks of API that use DBNull, and they can't be changed.
