Hi 

I am trying to keep showing  header when user scroll using this code

<DisplayLayout CellClickActionDefault="RowSelect"
                    Name="dg1"
                    SelectTypeRowDefault="Extended" Version="4.00" ViewType="Flat"
                    AllowColSizingDefault="Free"
                    HeaderClickActionDefault= "SortMulti" ColWidthDefault=""
                    AllowSortingDefault="OnClient"                     
                    RowSizingDefault="Free" SelectTypeColDefault="Single"
                    RowHeightDefault="18px" SelectTypeCellDefault="Extended"
                    BorderCollapseDefault="Separate" TableLayout="Fixed" StationaryMargins="Header" UseFixedHeaders="true">

but is not working properly, it is showing a large space between headers and content, and even when scrolling, the header disappear
