How to set the default namespace for the subfolder in ide

[Q. John Chen]

I have a ASP.NET web project. I made the default namespace for the
project "myns" and the ide automatically append the folder name into
the namespace for a reason.

I can live with this by simply changing the namespace to myns after
the empty templet code generated.

Now I created some TypedDataSet. The code is generated everytime I
make some changes. I don't want to change the generated code
everytime.

So, is there a way make the subfolder's default namespace also to be
"myns"?

Thanks

John
