Vertical Scrollbar issue....please help

When I use:

.aw-strict .aw-grid-row {height: auto;}
.aw-grid-cell .aw-item-text {height: auto;}
.aw-text-normal .aw-templates-text {white-space:normal;height: auto;}


The vertical scrollbar does not appear. What can I do??

Thank you!

The grid control does not currently support the rows with variable height.
