Filter Content Editor Tree to Only Display Japanese Items

Question

Is there a way to filter the content editor tree to only display items in the tree if they have Japanese versions?

Answer 1

Not out of the box. In theory, you will need to override the Content Editor Form. It is found in the following path: website\sitecore\shell\Applications\Layouts\IDE\Editors\Content Editor\IDE Content Editor.xml

You will need to change the CodeBeside and set it to your custom namespace. I decompiled the code, and if I am not mistaken, you will need to change the following method to accommodate your requirement:

protected virtual Sidebar GetSidebar()
{
    Sitecore.Shell.Applications.ContentManager.Sidebars.Tree result = new Sitecore.Shell.Applications.ContentManager.Sidebars.Tree();
    result.ID = "Tree";
    result.DataContext = new DataContext()
    {
        DataViewName = "Master"
    };
    return (Sidebar) Assert.ResultNotNull<Sitecore.Shell.Applications.ContentManager.Sidebars.Tree>(result);
}

You can also override the Tree Method to make it take into consideration of the language version you require.

In the Tree Class, you will need to override the following method to pass the language version.

public virtual string RenderChildNodes(ID parent)
{
    Assert.ArgumentNotNull((object) parent, "parent");
    Assert.IsNotNull((object) this.FolderItem, "FolderItem");
    Item currentItem = this.FolderItem.Database.GetItem(parent, this.FolderItem.Language);
    HtmlTextWriter output = new HtmlTextWriter((TextWriter) new StringWriter());
    if (currentItem != null)
    {
        foreach (Item filterChild in this.FilterChildren(currentItem))
        this.RenderTreeNode(output, filterChild, string.Empty, filterChild.ID == this.FolderItem.ID);
    }
    return output.InnerWriter.ToString();
}
