Class MergeParentContextViewDataAttribute

This attribute can be used for when child actions execute and will automatically merge in the viewdata from the parent context to the child action result.

Inheritance

System.Object

Namespace: Umbraco.Web.Mvc

Assembly: Umbraco.Web.dll

Syntax

public class MergeParentContextViewDataAttribute : ActionFilterAttribute

Remarks

This will retain any custom viewdata put into the child viewdata if the same key persists in the parent context's view data. You can always still access the parent's view data normally. This just simplifies working with ChildActions and view data.

NOTE: This does not mean that the parent context's view data will be merged before the action executes, if you need access to the parent context's view data during controller execution you can access it normally.

NOTE: This recursively merges in all ParentActionViewContext ancestry in case there's child actions inside of child actions.

Methods

OnResultExecuting(ResultExecutingContext)

Merge in the parent context's view data if this is a child action when the result is being executed

Declaration

public override void OnResultExecuting(ResultExecutingContext filterContext)

Parameters

Type	Name	Description
ResultExecutingContext	filterContext
