Hi.
You need to implement RTL (right to left) reading in your text box\label? Try apply WS_EX_RTLREADING style to your control (i never used that, but should work). You can download OpenNetCF open source library to get experience with windows native. There are a lot of code like code i provide for you:
// as that style exists in winuser.h we define following:

// #define WS_EX_RTLREADING        0x00002000L

readonly int WS_EX_RTLREADING = unchecked(0x00002000L);
 

public enum GetWindowLongType : int {

  EXSTYLE = -20,

  HINSTANCE = -6,

  HWNDPARENT = -8,

  ID = -12,

  STYLE = -16,

  USERDATA = -21,

  WNDPROC = -4

}
 

[Flags]

public enum SetWindowPositionFlags {

	ASYNCWINDOWPOS = 0x4000,

	DEFERERASE = 0x2000,

	DRAWFRAME = 0x20,

	FRAMECHANGED = 0x20,

	HIDEWINDOW = 0x80,

	NOACTIVATE = 0x10,

	NOCOPYBITS = 0x100,

	NOMOVE = 2,

	NOOWNERZORDER = 0x200,

	NOREDRAW = 8,

	NOREPOSITION = 0x200,

	NOSENDCHANGING = 0x400,

	NOSIZE = 1,

	NOZORDER = 4,

	SHOWWINDOW = 0x40

}
 

[DllImport("coredll.dll", SetLastError=true)]

public static extern int GetWindowLong(IntPtr hWnd, GetWindowLongType gwlType);
 

[DllImport("coredll.dll", SetLastError=true)]

public static extern void SetWindowLong(IntPtr hWnd, 

    GetWindowLongType gwlType, int nValue);
 
 

[DllImport("coredll.dll", SetLastError=true)]

public static extern int SetWindowPos(IntPtr hWnd, HWND pos, 

    int X, int Y, int cx, int cy, SetWindowPositionFlags uFlags);
 

public bool RightToLeftReading {

  get {

    if ((GetWindowLong(this.Handle, GetWindowLongType.EXSTYLE) & WS_EX_RTLREADING)

        == WS_EX_RTLREADING) {

      // WS_EX_RTLREADING flag exists

      return ( true );

    } else {

      // WS_EX_RTLREADING flag does not exists

      return ( false );

    }

  }

  set {

    if (RightToLeftReading != value)

    if ( value ) {

      int longFlags = GetWindowLong(this.Handle, GetWindowLongType.EXSTYLE);

      SetWindowLong(this.Handle, GetWindowLongType.EXSTYLE, longFlags | WS_EX_RTLREADING);

      SetWindowLong(this.Handle, GetWindowLongType.EXSTYLE, longFlags | WS_EX_RTLREADING);

      // update control

      SetWindowPos(hwnd, HWND.TOPMOST, 0, 0, 0, 0, 

         SetWindowPositionFlags.DRAWFRAME | 

         SetWindowPositionFlags.NOACTIVATE | 

         SetWindowPositionFlags.NOMOVE | 

         SetWindowPositionFlags.NOSIZE);

    } else {

      int longFlags = GetWindowLong(this.Handle, GetWindowLongType.EXSTYLE);

      // try set two times because of SetWindowLong CE bugs

      SetWindowLong(this.Handle, GetWindowLongType.EXSTYLE, longFlags & ~WS_EX_RTLREADING);

      SetWindowLong(this.Handle, GetWindowLongType.EXSTYLE, longFlags & ~WS_EX_RTLREADING);

      // update control

      SetWindowPos(hwnd, HWND.TOPMOST, 0, 0, 0, 0, 

         SetWindowPositionFlags.DRAWFRAME | 

         SetWindowPositionFlags.NOACTIVATE | 

         SetWindowPositionFlags.NOMOVE | 

         SetWindowPositionFlags.NOSIZE);

    }

  }

}

Oh, if that works don't forget to check is control created in design time or not. Because in design time we can't access native functions from coredll.dll. You should do something like this:

if ( Site == null || (Site != null && !Site.IsDesignTime) || !IsDesignTime()) {

  // call native methods

} else {

  // try to implement native methods by yourself (or use same native methods but from normal Windows not CE)

}

...

public static bool IsDesignTime()

{

        Assembly assembly = typeof(int).Assembly;

        return ((assembly != null) && assembly.FullName.ToUpper().EndsWith("B77A5C561934E089"));

}
