I've been trying to get my head around this and getting nuts trying. ;)
I have a mediaitem that gets filled with DAMP, and am trying to check whether it exists using razor.
To do this, I tried two different ways, but none of them worked.
The first one I tried was:
if (currentPage.largeBanner.mediaItem != null)
That didn't do a thing, the error remains, which is logical in a way, as the xml contains only an empty CDATA, which is a string and no XML
Then I tried:
if (currentPage.largeBanner != "")
This works, when there is in fact no mediaitem present. However, that one won't work when there actually IS one present.
Anyone got the golden tip for me? The thing I overlooked?
Thanks in advance!
Hi hopefully this helps
instead of using
if (Model.largeBanner != "")
you can try
if (Model.largeBanner is int)
this will make sure that the dynamic type returned is of type int which means that the property is assigned and pointing to a mediaID
Casting first to a string and then check if the string is not empty seems to work also.But maybe this causes some overhead. Not sure about that.
if (currentPage.largeBanner.ToString() != "")
Yep didn't think of that, that would be great as well :)Alright have a great day glenn.
Unfortunately, that didn't solve it either. Appearantly when it has a banner, it has a completely different structure from when it doesn't have a banner.
