How to determine if an EPiServer Composer function is placed in another Composer function

by Andreas Nylin 9. November 2009 09:56

Sometimes it can be handy to know if a Composer function is placed directly on the page or if it's placed in another Composer function. Here is a piece of code I wrote that does the trick.
The property must be placed in a class that derives from Dropit.Extension.Core.BaseContentFunction

private bool ParentIsContentFunction
{
    get
    {
        // Make sure that the current page is an Composer page
        if (this.CurrentExtensionPageData != null)
        {
            ContentFunctionData currentContentFunctionData = new ContentFunctionData(this.ContentFunctionLink);
            
            // Loop through all content areas in the page
            foreach(ContentAreaData ca in this.CurrentExtensionPageData.ContentAreas)
            {    
                // If any of the content areas contains the current content function it means that the function is placed directly on the page
                // - it's not placed in another content function
                if (ca.ContentFunctions.Contains(currentContentFunctionData))
                    return false;
            }
        }
        
        // If we reach this code it means that the content function is placed in another content function
        return true;
    }
}

It will be also encouraging to the author if we all could pass it around (for many of us who use social media such as a digg, twitter,..). Again, Thanks..

Конечно, есть и такие женщины, которые не скрывают своих лесбийских наклонностей. Они все имеют пару, но, время от времени позволяют себе расслабиться в компании девиц легкого поведения. Есть и такие, которые живут с мужем, но муж нормально относится к пристрастиям своей жены, они даже вместе посещают проституток, что бы, никому не было обидно. Такая услуга, как «семейным парам», пользуется огромным успехом, и проститутки Сочи очень часто ее предоставляют.
