Hi,
I would like to list out all files of a directory.
To do that, I created a CFileInfo class with string members (strName, 
strDate, strLength...) and I fill an ArrayList with those object.
It works good, I can get an ArrayList with all CFileInfo objects that 
contain strName, strDate, strLength...

The problem is how to show a member of an object embeded in an ArrayList?

I get an "Exception Details: System.Web.HttpException: DataBinder.Eval: 
'www.adm.ascx.CFileInfo' does not contain a property with the name 
CFileInfo.
" error for this line
<%#DataBinder.Eval(Container.DataItem, "CFileInfo.strName")%>

It's not a problem to do that with a datagrid and a DB, but using an 
ArrayList is a little more difficult for me...

Any idea...

Thanks.

You should probably just use strName not CFileInfo.strName. Your
properties need to be public, you could even set these in the designer
instead of using Eval. You could also use the built in fFile object.
