ListView Background Image in .NETCF

In this short entry I’d like to demonstrate how to display a background image in the ListView control. For this we will send the LVM_SETBKIMAGE or the LVM_GETBKIMAGE message to the ListView control with the LVBKIMAGE struct as the LPARAM. Unfortunately, the Windows CE version of LVBKIMAGE does not support LVBKIF_SOURCE_URL flag which allows using an image file on the file system for the background image of the ListView.

The layout of the background image can be either tiled or specified by an offset percentage. The background image is not affected by custom drawing, unless of course you decide to fill each sub item rectangle. For setting the background image we use the LVBKIF_SOURCE_HBITMAP flag together with the layout which is either LVBKIF_STYLE_TILE or LVBKIF_STYLE_NORMAL. If we set the layout to LVBKIF_STYLE_NORMAL, then we have the option of setting where the image will be drawn by setting the value of xOffsetPercentage and yOffsetPercentage.

In this example I’d like to make use of extension methods to add the SetBackgroundImage() and GetBackgroundImage() methods to ListView. This can of course be easily used to in a property to an inherited ListView.

public static class ListViewExtensions
    static extern int SendMessage(IntPtr hWnd, int Msg, int wParam, ref LVBKIMAGE lParam);
    const int LVM_FIRST = 0x1000;
    const int LVM_SETBKIMAGE = (LVM_FIRST + 138);
    const int LVM_GETBKIMAGE = (LVM_FIRST + 139);
    const int LVBKIF_SOURCE_NONE = 0x00000000;
    const int LVBKIF_SOURCE_HBITMAP = 0x00000001;
    const int LVBKIF_STYLE_TILE = 0x00000010;
    const int LVBKIF_STYLE_NORMAL = 0x00000000;
    struct LVBKIMAGE
        public int ulFlags;
        public IntPtr hbm;
        public IntPtr pszImage; // not supported
        public int cchImageMax;
        public int xOffsetPercent;
        public int yOffsetPercent;
    public static void SetBackgroundImage(this ListView listView, Bitmap bitmap)
        SetBackgroundImage(listView, bitmap, false);
    public static void SetBackgroundImage(this ListView listView, Bitmap bitmap, bool tileLayout)
        SetBackgroundImage(listView, bitmap, tileLayout, 0, 0);
    public static void SetBackgroundImage(
        this ListView listView,
        Bitmap bitmap,
        bool tileLayout,
        int xOffsetPercent,
        int yOffsetPercent)
        LVBKIMAGE lvBkImage = new LVBKIMAGE();
        if (bitmap == null)
            lvBkImage.ulFlags = LVBKIF_SOURCE_NONE;
            lvBkImage.ulFlags = LVBKIF_SOURCE_HBITMAP | (tileLayout ? LVBKIF_STYLE_TILE : LVBKIF_STYLE_NORMAL);
            lvBkImage.hbm = bitmap.GetHbitmap();
            lvBkImage.xOffsetPercent = xOffsetPercent;
            lvBkImage.yOffsetPercent = yOffsetPercent;
        SendMessage(listView.Handle, LVM_SETBKIMAGE, 0, ref lvBkImage);
    public static Bitmap GetBackgroundImage(this ListView listView)
        LVBKIMAGE lvBkImage = new LVBKIMAGE();
        lvBkImage.ulFlags = LVBKIF_SOURCE_HBITMAP;
        SendMessage(listView.Handle, LVM_GETBKIMAGE, 0, ref lvBkImage);
        if (lvBkImage.hbm == IntPtr.Zero)
            return null;
            return Bitmap.FromHbitmap(lvBkImage.hbm);

Here’s an example of exposing the background image as a property in an inherited ListView by using the extension methods above.

class ListViewEx : ListView
    public Bitmap BackgroundImage
        get { return this.GetBackgroundImage(); }
        set { this.SetBackgroundImage(value, BackgroundLayout == BackgroundImageLayout.Tile); }
    public BackgroundImageLayout BackgroundLayout { get; set; }
    public enum BackgroundImageLayout

A small catch with the ListView background image is that it is only supported in Windows CE 5.0 and later. Hope you found this information useful.

  1. Hi,

    Thanks for the post and the info. However i am not sure how to make the Listview control use the extensions. Do i define the extensions class in the same file ?


  2. Hi Mindecode,

    You need at least 2 things: Your project needs to be targetting .NETCF 3.5 and you need the namespace of this extension method imported (using) into the class your working on.
