Hi Konrad,
The BackgroundImage does not take effect for ListView, as a work around
you may draw the Background Image
via the LVM_SETBKIMAGE Message, here is a code snippet.
If you still have problems on this issue, please be free to let me know!
Thanks for using MSDN Newsgroup!
<code>
[DllImport("ole32.dll")]
public extern static void CoUninitialize();
[DllImport("ole32.dll")]
public extern static int CoInitialize(int pReserved);
[DllImport("user32.dll")]
public extern static int SendMessage(IntPtr hwnd, uint msg, uint wParam,
uint lParam);
[DllImport("user32.dll")]
public extern static int SendMessage(IntPtr hwnd, uint msg, uint wParam,
LVBKIMAGE lParam);
private const int NOERROR = 0x0;
private const int S_OK = 0x0;
private const int S_FALSE = 0x1;
private const int LVM_FIRST = 0x1000;
private const int LVM_SETBKIMAGE = LVM_FIRST + 68;
private const int LVM_SETTEXTBKCOLOR = LVM_FIRST + 38;
private const int LVBKIF_SOURCE_URL = 0x02;
private const int LVBKIF_STYLE_TILE = 0x10;
private const uint CLR_NONE = 0xFFFFFFFF;
[StructLayout(LayoutKind.Sequential)]
public class LVBKIMAGE
{
public int ulFlags;
public IntPtr hbm;
public string pszImage;
public int cchImageMax;
public int xOffsetPercent;
public int yOffsetPercent;
}
void SetBackground()
{
string bkImgFile = @"C:\CoughDrop.JPG";
LVBKIMAGE tLBI = new LVBKIMAGE();
tLBI.pszImage = bkImgFile;
tLBI.cchImageMax = bkImgFile.Length + 1;
tLBI.ulFlags = LVBKIF_SOURCE_URL | LVBKIF_STYLE_TILE;
SendMessage(listView1.Handle, LVM_SETBKIMAGE,0,tLBI);
int res = SendMessage(this.listView1.Handle
,LVM_SETTEXTBKCOLOR,0,CLR_NONE);
}
