The CellEditor property gets you the custom cell editor if it exists, else it creates it. The CellEditor property creates an empty editor if it wasn't created before, so please pay attention when creating custom cell editors on the fly. You can use the HasCellEditor property to check whether a cell has associated a custom editor ( created using the CellEditor property ). You can have different type of editors in the same column using the CellEditor property. The CellEditor property builds a new editor for a specific cell. By default, the cell's editor is the default column's editor. Use the EditType property to specify an editor for the column.  Use the DeleteCellEditor method to clear a particular cell editor created using the CellEditor property. Use the CellEditorVisible property to hide the cell's editor. You can use the BeginUpdate, EndUpdate method to refresh the control.

The following VB sample assigns a date type editor to the first cell:

With Grid1.Items
    Dim h As EXGRIDLibCtl.HITEM
    h = .ItemByIndex(0)
    If Not .HasCellEditor(h, 0) Then
        With .CellEditor(h, 0)
            .EditType = DateType
        End With
    End If
End With

The following VB sample assigns a spin type editor with min and max values:

With Grid1.Items
    With .CellEditor(.FirstVisibleItem, 0)
        .EditType = SliderType
        .Option(exSliderWidth) = 0
        .Option(exSliderMin) = 5
        .Option(exSliderMax) = 10
    End With
End With

The following C++ sample assigns a date type editor to the first cell:

#include "Items.h"
#include "Editor.h"
void OnButton1() 
{
	CItems items = m_grid.GetItems();
	COleVariant vtItem( items.GetItemByIndex( 0 ) ), vtColumn( (long)0 );
	if ( !items.GetHasCellEditor( vtItem, vtColumn ) )
	{
		CEditor editor = items.GetCellEditor( vtItem, vtColumn );
		editor.SetEditType( 7 /*DateType*/ );
	}
}

The following C++ sample assigns a spin type editor with min and max values:

#include "Items.h"
#include "Editor.h"
CItems items = m_grid.GetItems();
CEditor editor = items.GetCellEditor( COleVariant( items.GetFirstVisibleItem() ), COleVariant( long(0) ) );
editor.SetEditType( 20 /*SliderType*/ );
editor.SetOption( 41 /*exSliderWidth */, COleVariant( long(0) ) );
editor.SetOption( 43 /*exSliderMin*/, COleVariant( long(5) ) );
editor.SetOption( 44 /*exSliderMax*/, COleVariant( long(10) ) );

The following VB.NET sample assigns a date type editor to the first cell:

With AxGrid1.Items
    Dim h As Integer = .ItemByIndex(0)
    If Not .HasCellEditor(h, 0) Then
        With .CellEditor(h, 0)
            .EditType = EXGRIDLib.EditTypeEnum.DateType
        End With
    End If
End With

The following VB.NET sample assigns a spin type editor with min and max values:

With AxGrid1.Items
    With .CellEditor(.FirstVisibleItem, 0)
        .EditType = EXGRIDLib.EditTypeEnum.SliderType
        .Option(EXGRIDLib.EditorOptionEnum.exSliderWidth) = 0
        .Option(EXGRIDLib.EditorOptionEnum.exSliderMin) = 5
        .Option(EXGRIDLib.EditorOptionEnum.exSliderMax) = 10
    End With
End With

The following C# sample assigns a date type editor to the first cell:

int h = axGrid1.Items[0];
if ( !axGrid1.Items.get_HasCellEditor( h, 0 ) )
{
	EXGRIDLib.Editor editor = axGrid1.Items.get_CellEditor( h, 0 );
	if ( editor != null )
		editor.EditType = EXGRIDLib.EditTypeEnum.DateType;
}

The following C# sample assigns a spin type editor with min and max values:

EXGRIDLib.Editor editor = axGrid1.Items.get_CellEditor(axGrid1.Items.FirstVisibleItem, 0);
editor.EditType = EXGRIDLib.EditTypeEnum.SliderType;
editor.set_Option(EXGRIDLib.EditorOptionEnum.exSliderWidth, 0);
editor.set_Option(EXGRIDLib.EditorOptionEnum.exSliderMin, 5);
editor.set_Option(EXGRIDLib.EditorOptionEnum.exSliderMax, 10);

The following VFP sample assigns a date type editor to the first cell:

with thisform.Grid1.Items
	thisform.Grid1.BeginUpdate()
	.DefaultItem = .ItemByIndex( 0 )
	if ( !.HasCellEditor( 0, 0 ) )
		.CellEditor( 0, 0 ).EditType = 7
	endif
	thisform.Grid1.EndUpdate()
endwith

The following VFP sample assigns a spin type editor with min and max values:

with thisform.Grid1.Items
    with .CellEditor(.FirstVisibleItem, 0)
        .EditType = 20 && SliderType
        .Option(41) = 0  && exSliderWidth
        .Option(43) = 5 && exSliderMin
        .Option(44) = 10 && exSliderMax
    endwith
