Use the CellImage property to assign a single icon to a cell. Use the CellImages property to assign multiple icons to a cell.  Use the Images method to assign icons to the control at runtime. You can add images at design time by dragging a file to image editor of the control. The CellImage = 0 removes the cell's image. The collection of Images is 1 based. The CellImageClick event occurs when the cell's image is clicked. Use the ItemFromPoint property to retrieve the part of the control being clicked. Use the CellHasCheckBox property to add a check box to a cell. Use the CellHasRadioButton property to assign a radio button to a cell. Use the CellPicture property to load a custom size picture to a cell.

The following VB sample sets cell's image for the first column while new items are added ( to run the sample make sure that control's images collection is not empty):

Private Sub Gantt1_AddItem(ByVal Item As EXGANTTLibCtl.HITEM)
    Gantt1.Items.CellImage(Item, 0) = 1
End Sub

The following VB sample changes the cell's image when the user has clicked on the cell's image ( to run the following sample you have to add two images to the gantt's images collection. ),

Private Sub Gantt1_AddItem(ByVal Item As EXGANTTLibCtl.HITEM)
    Gantt1.Items.CellImage(Item, 0) = 1
End Sub

Private Sub Gantt1_CellImageClick(ByVal Item As EXGANTTLibCtl.HITEM, ByVal ColIndex As Long)
    Gantt1.Items.CellImage(Item, ColIndex) = Gantt1.Items.CellImage(Item, ColIndex) Mod 2 + 1
End Sub

The following C++ sample displays the first icon in the focused cell:

#include "Items.h"
CItems items = m_gantt.GetItems();
items.SetCellImage( COleVariant( items.GetFocusItem() ), COleVariant( (long)0 ), 1 );

The following C# sample displays the first icon in the focused cell:

axGantt1.Items.set_CellImage(axGantt1.Items.FocusItem, 0, 1);

The following VB.NET sample displays the first icon in the focused cell:

With AxGantt1.Items
    .CellImage(.FocusItem, 0) = 1
End With

The following VFP sample displays the first icon in the focused cell:

with thisform.Gantt1.Items
	.DefaultItem = .FocusItem
	.CellImage(0,0) = 1
endwith

Note: A cell is the intersection of an item with a column. All properties that has an Item and a ColIndex parameters are referring to a cell. The Item parameter represents the handle of an item, and the ColIndex parameter indicates an index ( a numerical value, see Column.Index property ) of a column , the column's caption ( a string value, see Column.Caption property ), or a handle to a cell. Here's few hints how to use properties with Item and ColIndex parameters:

Gantt1.Items.CellBold(, Gantt1.Items.ItemCell(Gantt1.Items(0), 0)) = True

Gantt1.Items.CellBold(Gantt1.Items(0), 0) = True

Gantt1.Items.CellBold(Gantt1.Items(0), "ColumnName") = True
