Only write to page if property != null, in a PageList
The intel says that 'System.ComponentModel.Container' will bind it, but it doesnt work!

Maybe something like this:
<%# Container.CurrentPage["EventDate"] != null ? ((DateTime)Container.CurrentPage["EventDate"]).ToString() : string.Empty%>

Johan: many many thanks. However that code gave some casting error. But I tried this and it worked:
<%# Container.CurrentPage["EventDate"] != null ? (Container.CurrentPage["EventDate"]).ToString() : string.Empty %>
Can you also write this?
<%# Container.CurrentPage["EventDate"] != null ? (Container.CurrentPage["EventDate"]) : null %>
There is however a little caveat. You see the code is like this really:
<itemTemplate>
<h3 style="...">
<%# Container.CurrentPage["EventDate"] %>
</h3>
</itemTemplate>
So, if I also want to get rid of the h3? But you solution will certenly work, and Iam very gratefull. Thanks.

Ah! You can do like this:
<%# Container.CurrentPage["EventDate"] != null ? ("<htmlCode>"+Container.CurrentPage["EventDate"]).ToString() : string.Empty%>

I just assumed EventDate was a DateTime-property... If it's just a short string:
<%# Container.CurrentPage["EventDate"] != null ? "<htmlCode>" + Container.CurrentPage["EventDate"].ToString() + "</htmlCode>" : string.Empty%>
Or use a PlaceHolder if you need your HTML more readable and not inside code blocks:
<asp:PlaceHolder runat="server" Visible='<%# Container.CurrentPage["EventDate"] != null%>'>
<h3 style="...">
<%# Container.CurrentPage["EventDate"] %>
</h3>
</asp:PlaceHolder>

Hi all!
I have a PageList and it lists propertys from child pages, like this.
<itemTemplate>
<%# Container.CurrentPage["EventDate"] %>
</itemTemplate>
Now, if the editor havent written anything in the property on the child's page type I dont want it to be written on the page. So, I tried
<% if (Container.CurrentPage["EventDate"] != null) { %>
<%# Container.CurrentPage["EventDate"] %>
<% } %>
But that doesnt work. Neither does (because it is always null)
<% if (CurrentPage["EventDate"] != null) { %>
<%# Container.CurrentPage["EventDate"] %>
<% } %>
How do I solve it? And please, as easy as possible! =) Thank you very much.
