Using XForms with Page Type Builder

A former colleague of mine, Cecilia, just asked me how to access information about a XForm when using Page Type Builder. Normally when you use Page Type Builder you access the value of (EPiServer) properties with code properties such as this:

[PageTypeProperty]
public virtual string MyProperty { get; set; }

//Or..

[PageTypeProperty]
public virtual string MyProperty
{
    get
    {
        return this.GetPropertyValue(page => page.MyProperty);
    }
}

But when it comes to a XForm you probably won’t be interested in the property’s value but instead in the property it self, or perhaps as in Cecilia’s case, in the property’s Form property from which you can get information about the form such as the form’s name. To make your code property return the actual property you can implement it like this:

[PageTypeProperty(Type = typeof(PropertyXForm)]
public virtual PropertyXForm MyFormProperty
{ 
    get
    {
        return  (PropertyXForm) 
            this.Property[this.GetPropertyName(
                page => page.XFormTeaser)];
    } 
}

To instead make the code property return the actual XForm object you can implement it like this:

[PageTypeProperty(Type = typeof(PropertyXForm), Tab = typeof(Poll), SortOrder = 80, EditCaption = "Veckans fråga")]
public virtual XForm MyFormProperty
{ 
    get
    {
        return  ((PropertyXForm) 
            this.Property[this.GetPropertyName(
                page => page.XFormTeaser)]).Form;
    } 
}
