Hello Aubrey Ivan,
If your data is supposed to come from a Web Service you may use our dedicated WebServiceDataSource component. You may check the step-by-step tutorial How to: Connect to Google Books APIs.
In other cases, you may indeed use the ObjectDataSource component. We provide a sample with our demos that come with the installation of Telerik Reporting. The demos are deployed by default in (Telerik Reporting installation folder)\Examples\CSharp or VB (e.g. C:\Program Files (x86)\Progress\Telerik Reporting R3 2019\Examples\CSharp). The ReportLibrary project contains our CLR reports. The report using an ObjectDataSource is ListBoundReport in the sub-folder DataBinding of the project. The model (Car) and the data providing class (Cars) are in the same folder.
I suggest to test and if you have any difficulties you may open a support ticket and ask further questions.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
