Before I answer your question I would like to ask you which type of testing you are using, because you have written Coded UI , but also send a link and a picture with code-snippet for TestStudio and Telerik TestingFramework? And also how you are using it - you have installed via plug-in for Visual Studio or you have installed the whole TestStudio product?
If you are using the Telerik TestingFramework, then you can choose how to find it - by name, by id, etc. You can find more information in our help article Getting started with WPF UI Automation
If you are using Telerik UI for WPF and Telerik TestingFramework you can also take advantage of the integration between there products and have built in types of RadCartesianChart, RadGridView and their properties.
I'm looking forward to your reply.
