Question

The following code fails at runtime…

 Dim Id As Guid = CType(e.CommandArgument, Guid) 

It throws this exception…

 System.InvalidCastException was unhandled by user code Specified cast is not valid 

Why can’t I cast e.CommandArgument as a Guid?

Answer 1

Try:

Dim DeleteId As Guid = New Guid(Convert.ToString(e.CommandArgument)) 

This works…

 Dim DeleteId As Guid = New Guid(DirectCast(e.CommandArgument, String))
