Hi,

I had created dataGrid to view the data. But when i am trying to fetch 650 records i am getting This is denied to prevent denial of service exception.

How to handled data of more than 500 to view as i checked in DataCommunicator class there is 500 max rows restriction.

Hi,

In the UI Samples app, we have an example of displaying 1000 rows using a DataGrid. No special configuration is needed to display this amount of data.
