CheckBox and Scrollbar in one Cell

I have a grid with Checkboxes together with Text in several Cells. This works fine.

Some cells contain large text so I need a scrollbar.
When I put a scrollbar in the cell with grid.addscrollbar the checkbox disappears.

Isn't is possible to use both in one Cell?

AddScrollBar/AddCheckBox are mutually exclusive features. It is on or the other type. A possible solution is to put the checkbox in the cell via HTML.

Thank you for your quick answer
