<b>If we want to store data of books and we implement 2 language, let say English and Chinese, CMS use 2 rows to store in table. However, I want to store them all in 1 row. I thought a approach to implement, but there are some problem.</b>
<hr>
When I created the document template "Book", I created enough fields for both lang version (e.g. EnglishBookName and ChineseBookName). I built the pages (menu) for under these 2 lang culture. Content Editor only need to create document type as "Book" under a language, let say English, but he had to fill all fields (BOTH EnglishBookName and ChineseBookName).

I created 2 transformations, "englishview" and "chineseview".
englishview:
<%# DataBinder.Eval(Container, "DataItem.EnglishBookName") %>
chineseview:
<%# DataBinder.Eval(Container, "DataItem.ChineseBookName") %>

I used Sessions to store the current culture, and use cmsdatalist the retrieve the data in the aspx file.
<% If sessionCulture = "en-us" Then %>
<cc1:cmsdatalist id="Book_EnglisgView" SelectNodesClassName="cms.Book" TransformationName="cms.Book.englishview" ... runat="server"></cc1:cmsdatalist>
<% ElseIf sessionCulture = "zh-tw" Then %>
<cc1:cmsdatalist id="Book_ChineseView" SelectNodesClassName="cms.Book" TransformationName="cms.Book.chineseview"... runat="server"></cc1:cmsdatalist>
<% End If %>

<b>Problem: ONLY english version work, because I did not create chinese version of that document. I believe my approach is wrong. I just want to know if there is any other solution can solve the problem(store 2 language in 1 row).</b>
