The example demonstrates three features related to RTL. They are controlled by the three top left (right) checkboxes.
RTL mode - texts from right to left. The browser page or its part is switched to RTL mode by dir='rtl' HTML attribute and TreeGrid shows in RTL.
Hirji dates - all dates in grid are shown in Persian Hirji calendar instead of Gregorian. Also all month and day names are translated to Persian.
Arabic digits - all digits in grid cells and dialogs are shown by Arabic digit characters instead of Latin
