Hi Minakshi,
Try these 3 approaches.
Suppose you want to set value for Rowcount dynamically.
1. gridObject.getQueryObject().setRowcount(<Value>);
2. gridObject.getQueryObject().setParameter("Rowcount", <Value>);
3. gridObject.getQueryObject().setProperty("Rowcount", <Value>);
here gridObject is the variable assigned to the i5Grid Object.
