Sorry about that. I meant "Fixed". "AutoFixed" probably works, too.

You might also need to set AllowRowLayoutCellSizing and AllowRowLayoutLabelSizing, but I think these will fall back to the RowSizing property, anyway.

there is no None in RowSizing enum.

Try setting grid.DisplayLayout.Override.RowSizing to None.

your code works very well but it enable the user to re size   the row height .

is there is a way to disable that?

        {  
            e.Layout.Bands[0].RowLayoutStyle = RowLayoutStyle.ColumnLayout;
