How to render PivotGrid using custom JSON data?
2 mins read
This KB illustrates that how to render PivotGrid using custom JSON data.
Solution:
The PivotGrid control normally gets rendered through the JSON data returned from WCF service after processing the report. You can also render the PivotGrid control by directly binding the custom JSON data structured in a format that is acceptable by PivotGrid.
WCF
