I don't think you have this out of the box in VS for managed code (ie "data based breakpoints").
The control you want to check is created from the ASPX markup ? If yes, you could use the https://www.codeproject.com/articles/667404/tag-mapping-in-asp-net feature.
You'll keep all your pages unchanged but behing the scene it will use now your own custom control. You can then override the code for the property you want and put a code breakpoint when a particular property is read or written.
Once done comment this tagMapping config and you are back to usual business.
