Setting right-to-left mode for a single grid cell

I'm displaying multiple translations of different languages (some of them being right-to-left languages) in a single grid. So I need to set right-to-left mode for a single grid cell but not for the whole grid.

I tried to use this code to achieve this behavior:

C#
private void Grid_RowCellStyle(object sender, RowCellStyleEventArgs e)  
{  
    if (translationColumns.Contains(e.Column))  
    {  
        var row = grid.GetRow(e.RowHandle) as TranslatableEntity;  

        if (row?.Locale != null)  
        {  
            e.Appearance.TextOptions.RightToLeft = row.Locale.GetCultureInfo().TextInfo.IsRightToLeft;  
        }  
    }  
}

This sets Appearance.TextOptions.RightToLeft for all cells that contain right-to-left content but the setting has no effect at all.

Additionally setting "RightToLeft=true" on the whole grid does not affect the behavior of tooltips. They are still in left-to-right mode.

Hi Matthias,

The capability of setting the Right To Left layout for a particular column or cell is not supported.

As a possible solution, you can draw a text in the Right To Left layout manually by using standard methods of the Graphics class. Take a look, for example, at the .net - Printing Right-To-Left in c# - Stack Overflow article, where the issue with drawing text in the RTL mode is discussed.

Let me know if you have additional questions.

dear expert

this code for single column RTL

Shared Sub CustomDrawCell(ByVal gridControl As GridControl, ByVal gridView As GridView)
' Handle this event to paint cells manually
AddHandler gridView.CustomDrawCell,
Sub(s, e)
If e.Column.VisibleIndex <> 4 Then
Return
End If

Dim drawFormat As StringFormat = New StringFormat()
drawFormat.FormatFlags = StringFormatFlags.DirectionRightToLeft
e.Appearance.DrawString(e.Cache, e.DisplayText, e.Bounds, drawFormat)
e.Handled = True

End Sub
End Sub

Thanks Alisher your support link is useful for me.
