How to tell the Visual Studio Designer to localize my custom server control?

Question

Hi,

I'm currently working on a custom server control. Now I came to the end of developing it and everything runs smoothly. I now just checked that also localization works fine and discovered that the Visual Studio designer doesn't add the meta:resourcekey="buttonNameResource" to my control. The localization works if I add the meta:resourceky manually, it is just a matter of making the Visual Studio designer add it automatically.

I have already added on my server control's public (and localizable) properties the [Localizable(true)] attribute, but it seems as if it doesn't has any effect.

Any suggestions?

Thanks
