Hi i successfully configured variations for my applications, http://server/en-us/default.aspx http://server/fr-fr/default. aspx but the problem is whenever i create lists or library's and Subsites in my English site which are not getting reflected(not propagating ) in French site. and how to translate custom web parts to use localization. any help is appreciated.............

One "quirk" with Variations is that lists and libraries are not considered, by SharePoint, to be Publishing Content even though they are in a Publishing site. As such, the Variations propagation will ignore lists and libraries. So you will have to re-create them by hand (or by template) for each variation site. Also, any changes that are made to the list items will also need to be made to the variation lists/libraries. To change this scenario, you'll need to write code in the form of a workflow, a timer job, or an event handler. As far as translating custom web parts, that too will involve code. If the web part was created in SharePoint Designer, I don't think there is much you can do. If you created it in Visual Studio, you can get the locale information from SPControl.GetContextWeb(this.Context).Locale.LCID.ToString() anduse that to access a resource file (I've done this) to translate common text in web parts.

Hi Tim, Thanks for your response. Siv
