Assembly: PresentationFramework (in PresentationFramework.dll)
- Type: System.IServiceProvider
An object that can provide services for the markup extension. In this implementation, this parameter can be null.
RelativeSource is simultaneously a markup extension implementation and a data object. When the extension returns itself, the relevant information is contained in the data. The main purpose of the markup extension is to allow a variable-argument constructor syntax in attribute form so that the FindAncestor mode can be defined inline, with the two extra arguments for ancestor type and level that the other modes do not require.
