How to use custom properties for XControls?

[Станев]

There is an article informing how to use XControls: https://www.ni.com/docs/en-US/bundle/labview/page/creating-xcontrol-properties.html

The problem is that I cannot find and article how to use them.

When I set a value to the property from a VI that uses the XControl, I cannot read this value in the XCOntrol Facade itself. I think the image will explain better:

So, https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000x2jVCAQ&l=en-US, item 4. Custom Properties for XControls provides some information.

Actually what is missing there is that one of sample code should be placed in the ....Write property.vi and the other- in the ...Read Property.vi.

The example bundled with LabView clarified the rest.
