Hi
Naveen Davuluri,
Greetings
from Syncfusion support.
The
error you're encountering, "Uncaught DataManager: Invalid arguments,"
suggests that the data source provided to the Syncfusion Grid might not be
correctly parsed or formatted.
We
are converting ptwGridDataJSON using JSON.parse() is the correct
approach if the data is initially in string format. Syncfusion Grids require
the dataSource to be an array of objects, so parsing the JSON string into an
appropriate JavaScript object format is necessary. If your data appears in the
grid as expected after this change, you are on the right track. It is essential
to ensure your API responses and any static JSON data are properly parsed when
used with front-end components like Syncfusion's Grid.
