Row Collections

The FlexGrid control has three sets of rows:

Header Rows: This collection contains the row of headers at the top of the grid.

Scrollable Rows: This collection contains all the rows of data displayed in the grid.

Footer Rows: This collection contains the footer rows at the bottom of the grid.

The three row collections are RowCollection objects, which extend regular arrays. You may add or remove rows by adding or removing Row objects from these arrays. In most cases, however, you won't add or remove scrollable rows, since the grid does that automatically when you set the itemsSource property.
