Some language locales require right-to-left support. We are fully committed to that and provide the best right-to-left support in the industry. In order for this to work, just use the respective language locale javascript file and set the RightToLeft property of the grid to true, e.g.
<trirand:JQGrid runat="server" ID="JQGrid1" RightToLeft="true">
</trirand:JQGrid>
