Casting to Interface at design time.

[Paul]

Hi all,

I am trying to cast my page to an Interface at design time with no joy.

sControl = ((IStatusPage)Page).[Interface code]

Despite this page 100% being inheriting this interface it will not
work.
I really do not want to cast to a class.

Any hints on where I am going wrong here?

Just as a hint .. if it doesn't work as stated, try rewriting it?

IStatusPage iPage = Page as IStatusPage;
if (iPage != null)
iPage.[interface code]

If nothing else, atleast you should be able to see if the "Page as
IStatusPage" is causing the problem, if so the class isn't interited from
IStatusPage after all.

Sorry,

The code is just fine at runtime.

It is only in Design mode the problem exists.
It seems that the Visual Studio IDE does not bother
to process inheritance.

I should has mentioned that I am using an

if( Page is IStatusPage)

before the line I pasted.

So while your code will work it doesn't solve the actual problem.

Thanks for taking the time to reply though.
