The second query helped me, but the first does not work if the grid type is set to "FilterBar".

From your query, we found that you want to use “FilterBar and “CheckBox” filter both are in the same Grid. But it is not feasible to use the “FilterBar” with any other Grid filters. Due to avoid the UI related issues we have prevented this action by default in Grid.
