I am currently evaluating your reporting tool.

I am building a report that has a webservice as the data source. The response object is json. For some reason the report designer does not parse an array within json. The element recentScans is not parsing properly. Attached is an image showing the data explorer. 

 

Here is data result for reference:

Hello Marie,

When the data field is an array or a collection of objects the nested objects' properties will not be visible or directly accessible. To access these properties you need to bind the recentScans data field to another Data Item.
This exact scenario is described step by step in How to: Connect to Google Books APIs (step 9).


If you need to use only the inner array/collection data in the report without any parent data fields, then querying the JSON is also an option - How to: Use JSONPath to filter JSON data. (This functionality is available in the latest internal build of Telerik Reporting.)

Nasko
