This code is already written in the help file under the Leadtools.Winforms.RasterImageListItem.Page Property section.  Here is a modified version of that code which provides enhanced resizing quality.

RasterCodecs.Startup()
Dim codecs as RasterCodecs = new RasterCodecs()
Dim info As CodecsImageInfo = codecs.GetInformation("c:\file.pdf", True)

Dim thumbnailRect As Rectangle = New Rectangle(0,0,rasterImageList.ItemImageSize.Width, rasterImageList.ItemImageSize.Height)
thumbnailRect = RasterImageList.GetFixedAspectRatioImageRectangle(info.Width, info.Height, thumbnailRect)

Dim rasterImage As RasterImage = codecs.Load("c:\file.pdf", thumbnailRect.Width, thumbnailRect.Height, info.BitsPerPixel, RasterSizeFlags.Bicubic, CodecsLoadByteOrder.Bgr)

Dim i As Integer=1
Do While i<=info.TotalPages
   Dim item As RasterImageListItem = New RasterImageListItem(rasterImage, i, "Page " & i)
   rasterImageList.Items.Add(item)
    i += 1
Loop
