property Items.CellBackColor([Item as Variant], [ColIndex as Variant]) as Color

Retrieves or sets the cell's background color.

TypeDescription
Item as Variant A long expression that indicates the item's handle
ColIndex as Variant A long expression that indicates the cell's handle or the column's index, a string expression that indicates the column's caption or the column's key
Color A color expression that indicates the cell's background color.
To change the background color for the entire item you can use ItemBackColor property. Use the ClearCellBackColor method to clear the cell's background color. Use the BackColor property to specify the control's background color. Use the CellForeColor property to specify the cell's foreground color. Use the ItemForeColor property to specify the item's foreground color. Use the SelectedItem property to specify whether an item is selected or unselected. Use the Def(exCellBackColor) property to specify the background color for all cells in the column. Use the Add method to add new skins to the control. You can define new skins and to use it to mark some cells, like in the following samples. Use the ConditionalFormats method to apply formats to a cell or range of cells, and have that formatting change depending on the value of the cell or the value of a formula.

The following VB sample changes the cell's appearance. The sample uses the "" skin to mark a cell:

With Grid1
    With .VisualAppearance
        .Add &H40, App.Path + "\cell.ebn"
    End With
    With .Items
        .CellBackColor(.FirstVisibleItem, 0) = &H40000000
    End With
End With

The following C++ sample changes the cell's appearance:

#include "Appearance.h"
#include "Items.h"
m_grid.GetVisualAppearance().Add( 0x40, COleVariant(_T("D:\\Temp\\ExGrid.Help\\cell.ebn")) );
m_grid.GetItems().SetCellBackColor( COleVariant( m_grid.GetItems().GetFirstVisibleItem() ), COleVariant( long(0) ), 0x40000000 );

The following VB.NET sample changes the cell's appearance.

With AxGrid1
    With .VisualAppearance
        .Add(&H40, "D:\Temp\ExGrid.Help\cell.ebn")
    End With
    With .Items
        .CellBackColor(.FirstVisibleItem, 0) = &H40000000
    End With
End With

The following C# sample changes the cell's appearance.

axGrid1.VisualAppearance.Add(0x40, "D:\\Temp\\ExGrid.Help\\cell.ebn");
axGrid1.Items.set_CellBackColor(axGrid1.Items.FirstVisibleItem, 0, 0x40000000);

The following VFP sample changes the cell's appearance.

With thisform.Grid1
    With .VisualAppearance
        .Add(64, "D:\Temp\ExGrid.Help\cell.ebn")
    EndWith
    with .Items
    	.DefaultItem = .FirstVisibleItem
    	.CellBackColor(0,0) = 1073741824
    endwith
EndWith

In VB.NET or C# you require the following functions until the .NET framework will support them:

You can use the following VB.NET function: 
     Shared Function ToUInt32(ByVal c As Color) As UInt32
         Dim i As Long
	 i = c.R
	 i = i + 256 * c.G
	 i = i + 256 * 256 * c.B
	 ToUInt32 = Convert.ToUInt32(i)
     End Function
You can use the following C# function: 
private UInt32 ToUInt32(Color c)
{
	long i;
	i = c.R;
	i = i + 256 * c.G;
	i = i + 256 * 256 * c.B;
	return Convert.ToUInt32(i);
}

The following C# sample changes the background color for the focused cell:

axGrid1.Items.set_CellBackColor(axGrid1.Items.FocusItem, axGrid1.FocusColumnIndex, ToUInt32(Color.Red));

The following VB.NET sample changes the background color for the focused cell:

With AxGrid1.Items
    .CellBackColor(.FocusItem, AxGrid1.FocusColumnIndex) = ToUInt32(Color.Red)
End With

The following C++ sample changes the background color for the focused cell:

#include "Items.h"
CItems items = m_grid.GetItems();
items.SetCellBackColor( COleVariant( items.GetFocusItem() ), COleVariant( m_grid.GetFocusColumnIndex() ), RGB(255,0,0) );

The following VB sample changes the background color for the focused cell:

With Grid1.Items
    .CellBackColor(.FocusItem, Grid1.FocusColumnIndex) = vbRed
End With

The following VFP sample changes the background color for the focused cell:

with thisform.Grid1.Items
	.DefaultItem = .FocusItem
	.CellBackColor( 0, thisform.Grid1.FocusColumnIndex ) = RGB(255,0,0)
endwith

Note: The intersection of an item with a column defines a cell. Each cell is uniquely represented by its handle. The cell's handle is of HCELL type, that's equivalent with a long type. All properties of Items object that have two parameters Item and ColIndex, refer a cell.

The following lines are equivalents and each of them changes the bold font attribute of the first cell on the first item.

With Grid1
    .Items.CellBold(, .Items.ItemCell(.Items(0), 0)) = True
    .Items.CellBold(.Items(0), 0) = True
    .Items.CellBold(.Items(0)) = True
    .Items.CellBold(.Items.ItemByIndex(0)) = True
    .Items.CellBold(.Items.ItemByIndex(0), 0) = True
    .Items.CellBold(.Items(0), Grid1.Columns(0).Caption) = True
End With
