Reference - Macro methods

Macro expressions allow you to use a large variety of methods. The following categories list the methods according to the type of provided functionality:

Keep in mind that the recommended macro syntax is to use infix notation for the first parameter of methods.

For example: {% “word”.ToUpper() %} instead of {% ToUpper(“word”) %}

Transformations

Method

Return type

Parameters

Description

ApplyTransformation

string

  • IEnumerable collection
  • string transformationName
  • string contentBeforeTransformationName

Transform

string

  • IEnumerable collection

Applies ad-hoc transformation code (Text / XML type) to a collection of items, or a single item.

Note: To keep the macro syntax valid, you need to break all %} closing macro tags within the ad-hoc transformation code into separate strings.

When writing Text / XML transformations, you can use most ASCX transformation methods inside macro expressions.

Outside of transformations, the macro autocomplete only offers the methods under the Transformation namespace, for example Transformation.GetDocumentUrl(). However, you can manually enter the methods even without the namespace.
