PageType Field Data inside custom webpart ?

Maybe explain a bit more what you are trying to accomplish. Are you wanting to list out some items or display details on a page?

Typically custom webparts are created to preform specific functionality which is not in an existing webpart. Listing or displaying data from a page type is already covered in virtually every webpart Kentico supplies.

Hey Brenden I am trying to create a layout with custom webpart that uses data from two pagetypes and uses default data in-case their is no input by user. Think of more like a hero component accessing bussiness detail fields from one page type and background image and text from another.

I'd suggest using a repeater to get the main object you want to display, then create a custom transformation method or custom macro to perform the rest of your queries. We do this scenario quite often. Take a look at an ecommerce site. There are

/products/brands/collections/types/product-detail

If you want to display the Collection name for a given product detail, you can simply use a macro in your transformation to get that data like so:

{%CurrentDocument.Parent.Parent.DocumentName|(identity)GlobalAdministrator%}

Brenden, thanks I was able to render data with something similar, Now I am wondering How do you take care of default data or string empty checks ?

Are you simply checking to see if a field is empty or do you want to provide default data when the form is opened/saved?

If simply checking for empty, you can again use a macro like so:

{%if(FieldName != "") { "it's not empty" } else { "it's empty" }|(identity)GlobalAdministrator%}
