If enabled, the indicator is displayed at the left of a grid View. Cells divide the indicator into the following parts:

The band header indicator and column header indicator can contain the Quick Column Customization button and Quick Band Customization button, respectively.

Row indicator cells display the state of corresponding rows. Additionally, these cells can be used to expand/collapse master and group rows and their edges can be used to resize rows, if allowed.
