Hello Aubrey Ivan,
The recommended way to set the ObjectDataSource component is during design-time in one of our Report Designers. You can control what data is returned from the data source using Data Source Parameters.
Regarding the Report Sources supported in the HTML5 ASP.NET MVC Report Viewer only TypeReportSource and UriReportSource can be used out-of-the-box. InstanceReportSource is supported only with a Custom Report Resolver implemented on the server side.
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?
