A divider item uses the item's client area to display a single cell. The ItemDivider property specifies the index of the cell being displayed. In other words, the divider item merges the item cells into a single cell. Use the ItemDividerLine property to define the line that underlines the divider item. Use the LockedItemCount property to lock items on the top or bottom side of the control. Use the MergeCells method to combine two or multiple cells in a single cell. Use the SelectableItem property to specify the user can select an item. A divider item has sense for a control with multiple columns.

The following VB sample adds a divider item between two child items:

Private Sub Form_Load()
    With Grid1
        .BeginUpdate
            .DefaultItemHeight = 24
            .MarkSearchColumn = False
            .HeaderVisible = False
            .LinesAtRoot = exLinesAtRoot
            .HasButtons = exCircle
            With .Columns
                With .Add("Column 1")
                    .SortType = EXGRIDLibCtl.SortTypeEnum.SortCellData
                End With
                With .Add("Column 2")
                    .Visible = False
                End With
            End With
            
            With .Items
                Dim h As HITEM, g As HITEM
                h = .InsertItem(, , "Father")
                .InsertItem h, 1, "Son 1"
                g = .InsertItem(h, 50, "")
                .CellValue(g, 1) = "This is a bit of text that should appear between <b>Son 1</b> and <b>Son 2</b>"
                .CellValueFormat(g, 1) = exHTML
                .CellSingleLine(g, 1) = False
                .ItemDivider(g) = 1
                .ItemDividerLine(g) = EmptyLine
                .InsertItem h, 99, "Son 2"
                .ExpandItem(h) = True
            End With
        .EndUpdate
    End With
End Sub

The following VB sample adds a divider item, that's not selectable too:

With Grid1.Items
    Dim i As Long
    i = .AddItem("divider item")
    .ItemDivider(i) = 0
    .SelectableItem(i) = False
End With

The following C++ sample adds a divider item, that's not selectable too:

#include "Items.h"
CItems items = m_grid.GetItems();
long i = items.AddItem( COleVariant("divider item") );
items.SetItemDivider( i, 0 );
items.SetSelectableItem( i, FALSE );

The following C# sample adds a divider item, that's not selectable too:

int i = axGrid1.Items.AddItem("divider item");
axGrid1.Items.set_ItemDivider(i, 0);
axGrid1.Items.set_SelectableItem(i, false);

The following VB.NET sample adds a divider item, that's not selectable too:

With AxGrid1.Items
    Dim i As Integer
    i = .AddItem("divider item")
    .ItemDivider(i) = 0
    .SelectableItem(i) = False
End With

The following VFP sample adds a divider item, that's not selectable too:

with thisform.Grid1.Items
	.DefaultItem = .AddItem("divider item")
	.ItemDivider(0) = 0
	.SelectableItem(0) = .f.
