Assigning 2 Databinding Expressions To The Same Property

[Nathan Sokalski]

I have two databinding expressions (the first & last names from a DB) that I
want to assign to the text property of a Label so that the result is
LASTNAME,FIRSTNAME. At the moment, I have the following which I know works
when I use it by itself:

text='<%# DataBinder.Eval(Container,"DataItem.membernames.lname") %>'

What I need to do is somehow concatenate this databinding expression, a
comma, and another databinding expression for the first name (which looks
almost the same). How can I do this? Thanks.

text='<%# DataBinder.Eval(Container,"DataItem.membernames.lname") %>,<%#
DataBinder.Eval(Container,"DataItem.membernames.fname") %>'

That was my original attempt, but it gives me an error when I try to use it.
Here is the error I recieve when trying to do it that way:

Server Error in '/' Application.

If you want to see the "Detailed Compiler Output" or "Complete Compilation

will be happy to email them to you. Thank you for any help you can give.

Ok, try this then:

text='<%# DataBinder.Eval(Container,"DataItem.membernames.lname"), %><%#
DataBinder.Eval(Container,"DataItem.membernames.fname") %>'

I tried that, I got the same result as before:

I think, although I am not sure because I am not an expert on databinding,
that the two values need to be concatenated either somehow in the codebehind
file or using some kind of formatting technique. I have seen formatting
methods (not in databinding, but in other areas) where the format string
uses numbers to represent the different values in the same way that 0 is
often used in DataBinder.Eval's optional third parameter. I was wondering if
there was some way to do something similar to this (the only problem is that
I don't know of a way to create more than one value). Let me know if you
find any more ideas. Thanks.
