Hi Jacky,

Thank you for writing.

I managed to reproduce the described case and I can confirm it is an issue. I have logged it in our feedback portal. You can add your vote and subscribe for status updates here: http://feedback.telerik.com/Project/154/Feedback/Details/136288-fix-radgridview-setting-the-header-text-to-be-right-aligned-will-overlap-the-f

Your Telerik Points have been updated for this report. 

As a work around I can suggest setting the RightToLeft property of the desired header cells, in order to move the filtering button to the other end:

void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
    GridHeaderCellElement headerCell = e.CellElement as GridHeaderCellElement;
    if (headerCell != null && e.Column.Name == "DecimalColumn")
    {
        headerCell.RightToLeft = true;
    }
}

I hope that you find this information useful. Should you have any other questions, do not hesitate to contact us.
