Controlling Layout / Device Layout by culture

Question

I heard it is possible to control your device layout by which culture you are in. I can not find any documentation or examples on this. I see that you can choose a device layout by QueryString or some rules. But none of those rules seem to inspect the culture.

Can this be accomplish either by sitecore items or through code?

Answer 1

As far as I understand your problem, you have two layouts: old and new. Now you want to switch to the new layout step by step. You decided to add a new device (suppose "Default New") and set updated layout for it and then, using some mechanism like rules, redirect users to this device. But you can't found a solution how to do that.

I also didn't find any rules which match your requirements. I suggest you add your custom condition. Add code below to solution:

using System.Web;
using Sitecore.Data;
using Sitecore.Diagnostics;
using Sitecore.Rules.Conditions;
using Sitecore.Rules.Devices;

namespace Your.Namespase
{
    public class ContextLanguageCondition<T> : StringOperatorCondition<T> where T : DeviceRuleContext
    {
        private ID languageId;
        public ID LanguageId
        {
            get
            {
                return this.languageId;
            }
            set
            {
                Assert.ArgumentNotNull((object)value, "value");
                this.languageId = value;
            }
        }

    public ContextLanguageCondition()
    {
        this.LanguageId = ID.Null;
    }

    public ContextLanguageCondition(ID languageId)
    {
        Assert.ArgumentNotNull((object)languageId, "languageId");
        this.languageId = languageId;
    }

    protected override bool Execute(T ruleContext)
    {
        HttpContextBase httpContext = ruleContext.HttpContext;
        if (httpContext == null)
            return false;

        var lang = Sitecore.Context.Language;

        if (LanguageId == ID.Null || lang == null)
            return false;

        var langItemID = Sitecore.Data.Managers.LanguageManager.GetLanguageItemId(lang, Sitecore.Context.Database);

        if (langItemID == ID.Null)
            return false;

        return LanguageId == langItemID;
    }
}
}

Secondary, you need create a condition item in Sitecore. For example under "Context" Element Folder:

Data for creating rule:

Path: /sitecore/system/Settings/Rules/Definitions/Elements/Context

Text: where the language is [languageId,Tree,root=/sitecore/system/Languages,specific language]

Type: Your.Namespase.ContextLanguageCondition,Your.Namespase

Make sure you update the type with your library name.

After that, you can set the rule for a device:

If condition returns "true", the device will be switched
