Partial Classes, .Net 2.0 and Custom Attributes

[Julian Jelfs]

Hi,

I had an aspx pag in .Net 1.1 with a label on it. As such I had a code
behind page with a declaration for that label.

When I convert to Asp.Net 2.0 the code behind is converted to a partial
class and the declaration for the label is removed. This is what I expected
to happen and I understand why it has happened.

The problem I have is that I had added a custom attribute to my label
declaration which I use to handle localization. e.g.

[Localize]
protected System.Web.UI.WebControls.Label lScreenTitle;

Since that declaration has been removed, so has the custom attribute.

My question is, how do you add a custom attribute to a control on an aspx
page in Asp.Net 2.0 given that you no longer have access to the control's
declaration in the code-behind file?

Thanks,

Julian Jelfs.

If you need to add a custom attribute to the field, then don't use partial
classes and the new CodeFile directive. I think you're going to have a struggle
though, as the new VS.NET model doesn't want to do things the old way :)

BTW, since your attribute is called [Localize] I'm wondering if the new localization
model in 2.0 will suit your needs:

Thanks for the response. I have looked into the Asp 2 localization model and
it doesn't quite do what I want it to.

It seems like a bit of a problem that it is impossible to add an attribute
to a control added declaratively in design view. I can't believe there's no
way to do it. I do want to do things the 2005 way in every other regard
because it's easier and better.

The only other thing I could suggest is making a property on your page which
sets the text on the Label and then aoontate thge property w/ your custom
attribute.

Yes that's an idea I could try. It all starts to get a bit laborious then.

Agreed.

Let me ask why the built-in localization scheme doesn't work for you? If
you need more control over it you can build your own expression builder such
that you get to define your own <%$ %> syntax in the pages. That would then
invoke your code to do your own conditional localization.....

Well, the problem is that I don't really want it to be tied to culture. So
it's not really localization in that sense, it's rather the ability to
provide alternative sets of terminology (which might include a separate
langyage altogether) So I might have two different sets of terminology being
used within the same culture setting. That's really why I thought that the
language localization infrastructure provided by the .Net framework didn't
quite fit.

I also need to store my resources in a database rather than resource files,
but I think .Net 2 allows that right?

Yeah, that's why I suggested looking into your own custom Expression Builders.
Sounds like that's a perfect fit for your needs.
