You can use a wxsRestGateway.properties file to override data grid settings on the client side.
To override data grid settings on the client side, create an wxsRestGateway.properties file in the REST gateway for WebSphere® Application Server and other WebSphere servers to override default behavior.
Assume that the following XML file was paired with a deployment policy XML file, and these files were used to start a container server.
companyGridServerSide.xml
<?xml version="1.0" encoding="UTF-8"?>
<objectGridConfig xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

On a container server, the ObjectGrid instance named CompanyGrid behaves as defined by the companyGridServerSide.xml file. By default, the CompanyGrid client has the same settings as the CompanyGrid instance that is running on the server.
The following ObjectGrid XML file can be used to specify some of the attributes and plug-ins on the CompanyGrid client.

In this properties file, specify the client-side data grid configuration file, companyGridServerSide.xml, from step 1. See the following example of a wxsRestGateway.properties file:
objectGridClientXML=D:\\wxsRestConfig\\companyGridClientSide.xml
-Dwxs.restgateway.props=D:\wxsRestConfig\wxsRestGateway.properties
