When I add a template column to a DataGrid and bind some data from an object
in a collection using the following:
<% DataBinder.Eval (Container, "DataItem.Depar tment.Departmen tName") %>
What Namespace/Class is Eval located in and can I call if from code behind.
I have implemented my own version of reflection nased property navigation
but I'd really rather use the original wheel than reinvent it.

Eval is a static/shared member of the class DataBinder which is located in
System.Web.UI
There's no reason why you can't use it in codebehind.

I'm just thinking, it's a really usefull little method, expecially to use in
BLL, but I dont realyl want to have to add the System.Web.UI to my BLL. I
would like if the code that parses the property to get its value (from
Something.Somet hingElse) is accessible from a Reflection assembly class??

i believe you can via the PropertyInfo member and GetValue you can do a
google search for those and come up with some hits. Reflection might be a
powerful tool, but I'd take a long hard look to make sure it was really
necessary...I find it tends to make code less than readable.

True, but when was the last time Application Infrastructure codewas
generally readable LOL :p
Like I said, I do have some code that will parse a property and get its
value (or null) but figured that DataBinder.Eval (which does exacly the same
thing) must but making a call internally to a method that already does this.

I have an article "Metadata and Reflection in .NET" [1] explaining
some basics. Reflection is powerful but can hurt performance if it's
used in the wrong places.

The primary problem I've had with php is the lack of namespaces, which
makes OOP very difficult to organize, since you end up with large number

namespace when calling a class that may not have been included, you are
forced to store all of your classes in the same folder in your file
system. This...
