You can't cast an object to something that it isn't. You can only cast an object to it's actual class, any of it's base classes, or any of the interfaces that it implements.

C# is type safe, so the object contains information about it's actual type. When you do a cast, you cast the reference, but the object still remains the same type. Therefore, when you cast the DataTable reference to object, you get an object reference pointing to a DataTable object. You can't then cast this to msdatasrc.DataSource, as the actual type of the object does not inherit that class.

If the control can't use a DataTable as data source, you have to copy the data from the DataTable into something that the control can use.

Despite everything, the person most likely to be fooling you next is yourself.
