Got my hands on a 9.2.20092.2058 version and sure enough it worked..

thanks for your help

Fred

 Me.UltraCombo1.DisplayMember = CouleursColumn.Code.ToString

Most Columns are hidden

  For Each c As UltraGridColumn In e.Layout.Bands(0).Columns
            c.Hidden = True
        Next

        e.Layout.Bands(0).Columns(CouleursColumn.Image.ToString).Style = ColumnStyle.Image
        e.Layout.Bands(0).Columns(CouleursColumn.Code.ToString).Hidden = False

Using version 8.2.20082.1000

Would like to get my boss to pay for an upgrade soon.. but for now no go

Yeah I use UltraCombo1.InitializeRow

Hm.

The Code column is your DisplayMember column, right? Do you have any hidden columns here?

What version of the controls are you using? Maybe this is a bug in an old version.

What event are you using to apply the Image? IniitalizeRow?

Do I have to cast the Value to something else .  my datasource returns it as a {System.Array}

You mean your image column is an array? Okay, so your images are stored in a Byte array. That makes this a little trickier. I assume, in that case, that you also don't see the image in the DisplayMember column of the dropdown, either.

In that case, you have to convert that byte array into a System.Drawing.Image before you assign it to the Appearance. The grid does this for you in the column containing the byte array, but the Value of the cell will still return the Byte array data and not the image.

There's no really easy way to do this, and I don't have a sample with byte array data to test with, but I think what you can do is something like this:

private void ultraGrid1_InitializeRow(object sender, InitializeRowEventArgs e)
        {
            object imageCellValue = e.Row.Cells["Image column"].Value;
            Image image = GetImageRendererImage(e.Row, e.Row.Band.Columns["Image column"], imageCellValue);
            e.Row.Cells["DisplayMember Column"].Appearance.Image = image;
        }        

        internal static System.Drawing.Image GetImageRendererImage(UltraGridRow gridRow, UltraGridColumn gridColumn, object cellValue)
        {
            EmbeddableImageRenderer embeddableImageRenderer = gridRow.GetEditorResolved(gridColumn) as EmbeddableImageRenderer;
            if (embeddableImageRenderer == null)
            {
                Debug.Fail("GetImageRendererImage is only valid for cells that are using an EmbeddableImageRenderer");
                return null;
            }

            EmbeddableEditorOwnerBase editorOwner;
            object ownerContext;
            GetOwnerInfo(gridRow, gridColumn, out editorOwner, out ownerContext);
            Stream imageStream;
            bool disposeImage;
            return embeddableImageRenderer.GetImage(cellValue, editorOwner, ownerContext, out imageStream, out disposeImage);
        }

        
        internal static void GetOwnerInfo(UltraGridRow gridRow, UltraGridColumn gridColumn, out EmbeddableEditorOwnerBase editorOwner, out object ownerContext)
        {
            IGridDesignInfo iGridDesignInfo = gridRow.Band.Layout.Grid as IGridDesignInfo;
            editorOwner = iGridDesignInfo.GetEditorOwner(gridRow, gridColumn);
            ownerContext = gridRow;
        }
