Thanks Mike. Setting the ViewStyle property to MultiBand fixed it!

I'm a little confused. This code shows you setting the ViewStyle to SingleBand. So you cannot possibly be using OutlookGroupBy functionality. Unless something else is setting that property to OutlookGroupBy later on.

I also don't see anything here that sets the HeaderPlacement property.

Maybe you are loading a Layout into the grid at some point after this code and it's overriding the settings you are applying here.

Mike,

I tried exactly what you did, but it didn't work. I am wondering if something is working against this. My grid is an inherited grid. I am setting various properties in the New sub.

Public Sub New()
MyBase.New()

' This call is required by the Windows Form Designer.
InitializeComponent()

' Add any custom default settings
With Me.DisplayLayout.Override
.CellPadding = 0
.RowAppearance.BorderColor = Color.LightGray
.CellAppearance.BorderColor = Color.LightGray
.BorderStyleRow = UIElementBorderStyle.Dotted
.BorderStyleCell = UIElementBorderStyle.Dotted
.CellMultiLine = Infragistics.Win.DefaultableBoolean.True
.ColumnAutoSizeMode = UltraWinGrid.ColumnAutoSizeMode.AllRowsInBand
.HeaderStyle = HeaderStyle.WindowsVista
.RowSelectors = Infragistics.Win.DefaultableBoolean.False
.ColumnSizingArea = ColumnSizingArea.HeadersOnly
.FixedCellSeparatorColor = _
Color.FromArgb(CType(CType(85, Byte), Integer), CType(CType(127, Byte), _
Integer), CType(CType(170, Byte), Integer))
.RowAlternateAppearance.BackColor = _
Color.FromArgb(CType(CType(224, Byte), Integer), CType(CType(224, Byte), _
Integer), CType(CType(224, Byte), Integer))
.SelectTypeCell = Infragistics.Win.UltraWinGrid.SelectType.Extended
.AllowMultiCellOperations = AllowMultiCellOperation.Copy
.RowSizing = Infragistics.Win.UltraWinGrid.RowSizing.AutoFree
.AllowUpdate = Infragistics.Win.DefaultableBoolean.True
.AllowAddNew = Infragistics.Win.UltraWinGrid.AllowAddNew.No
.CellClickAction = UltraWinGrid.CellClickAction.RowSelect
.AllowRowSummaries = AllowRowSummaries.Default
.EditCellAppearance.BackColor = Color.White
.EditCellAppearance.ForeColor = Color.Black
End With
With Me.DisplayLayout
.ViewStyle = UltraWinGrid.ViewStyle.SingleBand
.EmptyRowSettings.Style = EmptyRowStyle.PrefixWithEmptyCell
.ScrollBounds = UltraWinGrid.ScrollBounds.ScrollToFill
.ScrollStyle = ScrollStyle.Immediate
.PriorityScrolling = True
.ScrollBarLook.ScrollBarArrowStyle = _
Infragistics.Win.UltraWinScrollBar.ScrollBarArrowStyle.Default
.AutoFitStyle = AutoFitStyle.ExtendLastColumn
.GroupByBox.Hidden = True
.AddNewBox.Hidden = False
.TabNavigation = Infragistics.Win.UltraWinGrid.TabNavigation.NextCell
End With

End Sub

I tried this out and it seems to be working fine for me.All I did was this:

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            UltraGridLayout layout = e.Layout;
            UltraGridBand band = layout.Bands[0];
            UltraGridOverride ov = layout.Override;

            layout.ViewStyleBand = ViewStyleBand.OutlookGroupBy;
            band.SortedColumns.Add("Int32 1", false, true);
            ov.HeaderPlacement = HeaderPlacement.OncePerRowIsland;            
        }

When I do this, I get headers at the top of each set of child rows under each group. Is that not what you want?

Hi Mike,

I had already tried the HeaderPlacement property. Does this require multiple bands to work correctly? I am using a single band and want to make it look like 'OncePerRowIsland' in the example in http://help.infragistics.com/Help/NetAdvantage/WinForms/2012.2/CLR4.0/html/WinGrid_Control_the_Placement_of_Headers.html
