Compatibilidade Menu ASP .NET 2.0 com Chrome

Aqui fica uma solução (a que experimentei e funcou):

Method 1

• 1) Go to Solution Explorer in Visual Studio and add “ASP.NET Folder” named “APP_Broswers”.
• 2) Add new item “Browser File” to this special folder and name it “safari.browser” for both browser Chrome as well as Safari.
• 3) Now Delete all per-added data from safari.browser file.
• 4) Now add the following tags to that browser file.
 Collapse | Copy Code

<browsers> 
    <browser refID="safari1plus"> 
        <controlAdapters> 
          <adapter controlType="System.Web.UI.WebControls.Menu" adapterType="" /> 
        </controlAdapters> 
    </browser> 
</browsers>

• 5) Now only you need is to save that file.
