I’m on 8.1.15 I want to build a binding on a label by using the third level parent meta name, is there a way to acheive this ? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/9/b9949c5b538101c861ef8c4f845058e194d7187f.png) I want to get the “DCM\_shot\_id” meta.name from the “value”, I have tried {parent.parent.parent.meta.name} but it doesn’t work. Anybody can help me with that ? ---

What are you trying to achieve? I am having a hard time imagining why you would want to change the name of a container at runtime. I can see how this could lead to many issues, such as breaking bindings. ---

I don’t want to change the name, I want to get the name to build a binding. I want to dynamise some labels based on the top parent… Ex.: label.text =\> DcmShotId \<= That result comes from a functions that use as inputs “DCM\_shot\_id”, so I want to get meta.name of my hierarchic parent {parent.parent.parent.meta.name} ---

In perspective, traversing up the hierarchy can be a bit different and I find the best way is to use the property explorer. For a property or expression binding, I believe that you’re looking for something like: `...../DCM_shot_id.meta.name` In script I think you would be looking for something like `self.parent.parent.parent.parent.getChild("DCM_shot_id").meta.name` ---

I know that, but I want to get it fully dynamically, I want to build a binding to not “hardcoded” the destination, I have no advantage to use it if I have to point the name that I want to get. In scripting I can do something like this: self.parent.parent.parent.meta.name ---

~~I don’t think you can build a dynamic property name in an expression.~~ You could do it in a script transform if you have something else to bind to, or you could perhaps add an event script to the value EDIT: Turns out there is an expression function. [https://docs.inductiveautomation.com/display/DOC81/property](https://docs.inductiveautomation.com/display/DOC81/property) ```auto property('this.someString' + {...../DCM_shot_id.meta.name}) ``` ---

[https://docs.inductiveautomation.com/display/DOC81/property](https://docs.inductiveautomation.com/display/DOC81/property) You can in Perspective, actually 🙂 I would have expected `{parent.parent.parent.etc}` to work, honestly. EDIT: It looks like an intentional restriction that I don't see a way around. I'm not sure what technical limitations are implied; someone else may have more luck playing around with things: [https://files.inductiveautomation.com/sdk/javadoc/ignition81/8.1.15/com/inductiveautomation/perspective/common/api/PropertyRef.html](https://files.inductiveautomation.com/sdk/javadoc/ignition81/8.1.15/com/inductiveautomation/perspective/common/api/PropertyRef.html) ---

I’m unable to get it working correctly, can you provide me an example, i want to get the parent.parent.parent.meta.name ---
