The CellImageClick event notifies your application that an icon in the cell is clicked. Use the CellImage property to assign an icon to a cell. Use the CellImages property to assign multiple icons to a cell. Use the ItemFromPoint property to get the index of icon being clicked, if the cell displays multiple icons using the CellImages property. The CellImageClick event is not fired if you are clicking a custom size picture added with the CellPicture property. Use the CellHasCheckBox or CellHasRadioButton property to assign a check box or a radio button to a cell. Use the CellStateChanged event to notify your application that the the cell's checkbox or radio button is clicked:

The following VB sample changes the cell's icon when the user clicks the icon:

Private Sub Grid1_CellImageClick(ByVal Item As EXGRIDLibCtl.HITEM, ByVal ColIndex As Long)
    With Grid1.Items
        .CellImage(Item, ColIndex) = (.CellImage(Item, ColIndex) Mod 2) + 1
    End With
End Sub

The following VB sample displays the index of icon being clicked, when the cell displays multiple icons ( CellImages property ):

Private Sub Grid1_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
    Dim i As HITEM, h As HitTestInfoEnum, c As Long
    With Grid1
        i = .ItemFromPoint(X / Screen.TwipsPerPixelX, Y / Screen.TwipsPerPixelY, c, h)
    End With
    If (i <> 0) Then
        If exHTCellIcon = (h And exHTCellIcon) Then
            Debug.Print "The index of icon being clicked is: " & (h And &HFFFF0000) / 65536
        End If
    End If
End Sub

The following C++ sample changes the cell's icon being clicked:

#include "Items.h"
void OnCellImageClickGrid1(long Item, long ColIndex) 
{
	CItems items = m_grid.GetItems();
	COleVariant vtItem( Item ), vtColumn( ColIndex );
	items.SetCellImage( vtItem , vtColumn , items.GetCellImage( vtItem, vtColumn ) % 2 + 1 );
}

The following VB.NET sample changes the cell's icon being clicked:

Private Sub AxGrid1_CellImageClick(ByVal sender As Object, ByVal e As AxEXGRIDLib._IGridEvents_CellImageClickEvent) Handles AxGrid1.CellImageClick
    With AxGrid1.Items
        .CellImage(e.item, e.colIndex) = .CellImage(e.item, e.colIndex) Mod 2 + 1
    End With
End Sub

The following C# sample changes the cell's icon being clicked:

private void axGrid1_CellImageClick(object sender, AxEXGRIDLib._IGridEvents_CellImageClickEvent e)
{
	axGrid1.Items.set_CellImage(e.item, e.colIndex, axGrid1.Items.get_CellImage(e.item, e.colIndex) % 2 + 1);
}

The following VFP sample changes the cell's icon being clicked:

*** ActiveX Control Event ***
LPARAMETERS item, colindex

with thisform.Grid1.Items
	.DefaultItem = item
	.CellImage( 0,colindex ) = .CellImage( 0,colindex ) + 1
