Thanks for that, I found this post.
I was having this problem as well.
Now I've hit another wall i need help with.
I need to programmatically filter this images.
this.TagItemKey = "test1";
Inside the create child controls overide. ANd its not filtering at all.
Should i be using the text name of the tag or the GUID? And do i have to call a method after this to Bind it? am i doing this the right way?
Thanks in Advance Ivan, ur a Champ.
