By default, the RightToLeft property is False. The RightToLeft gets or sets a value indicating whether control's elements are aligned to right or left. The RightTolLeft property affects all columns, and future columns being added.  Use the Alignment property to align all the cells in the column. Use the CellHAlignment property to align a particular cell. Use the HeaderAlignment property to align the column's caption in the control's header. Use the EditAlignment property to align the text inside the edit control, if present in the control's label. Use the Alignment property to align the drop down portion of the control relative to the control's label.

Changing the RightToLeft property on True does the following:

• displays the vertical scroll bar on the left side of the control
• flips the order of the columns ( Position property )
• change the column's alignment to right, if the column is not centered ( Alignment property, HeaderAlignment property, HeaderImageAlignment property )
• reverse the order of the drawing parts in the cells ( Def(exCellDrawPartsOrder) property to "caption,picture,icons,icon,check" )
• aligns the locked columns to the right ( CountLockedColumns property )
• aligns the control's group-by bar / sort bar to the right ( SortBarVisible property )
