localizing radiobuttonlist (or its elements)

[acadam]

Hi,
I have not found any info about localizinfg the elemtns of a
radiobuttonlist. I'd like to use .resx files for every languages
(className.ascx.resx, className.ascx.en-US.resx and so on...) but I
don't know how to do this.

First:
<asp:ListItem meta:resourceKey="option1">opt1</asp:ListItem>
<asp:ListItem meta:resourceKey="option2">opt2</asp:ListItem>
....
I set "option1" into the .resx file with its value and so on for the
other elements. This code doesn't return any error but doesn't run.

Second:
<asp:ListItem Text="<%$Resourcesption1%>">opt1</asp:ListItem>
....
I set "option1" into the .resx file with its value. Now I get an error
"It is not possibile to find the resource object with 'option1' key". I
don't know how to set the pathname, .resx file resides into
"App_LocalResources" folder.

Thank you very much!!
Excuse me for my bad English!!!
