In some applications, it makes sense to 'freeze' certain rows and/or columns to they remain in view even when the grid is scrolled. For example, you may want to keep a column with product names visible on the left of the grid and see the product data on the right of the grid.
The FlexGrid frozenRows and frozenColumns properties allow you to achieve that. Use these properties to define the portion of the grid that should remain fixed and those parts of the grid will remain in view as if they were header columns. However, they can still be selected or edited as if they were regular cells.
The example below allows you to freeze or unfreeze rows and columns by clicking the button.
Clicking "Freeze" keeps the rows and columns above and to the left of the selection visible while the rest of the grid scrolls. Clicking "Unfreeze" unlock all rows and columns so they become scrollable.
