You can subscribe to the rowexpand and rowcollapse events in order to keep track of the expanded rows in a grid. You can read more about these events in the jqxGrid API Documentation.
thanks for reply , but I was looking for some kind of property that could tell me if the row is in expanded or collapsed state.
Because on the click of one of the column I want to expand the row if it is collapsed and collapse it If it is expanded.
