# Error: ngRef:noctrl
A controller for the value of `ngRefRead` could not be found on the element.

    The controller for ngRefRead="{0}" could not be found on ngRef="{1}"

## Description

This error occurs when the ngRef directive specifies a value in `ngRefRead` that cannot be resolved to a directive / component controller.

Causes for this error can be:

1. Your `ngRefRead` value has a typo.
2. You have a typo in the registered directive / component name.
3. The directive / component does not have a controller.

Note that `ngRefRead` takes the name of the component / directive, not the name of controller, and also not the combination of directive and 'Controller'. For example, for a directive called 'myDirective', the correct declaration is `<div ng-ref="$ctrl.ref" ng-ref-read="myDirective">`.
