I am trying to use Printdocument to print the content of my Listview1. The first column is an image 16x16. The code recognize the .ImageIndex but the "Icon" column (first column) stays empty.
Code:Private Sub PrintDetails(ByRef e As System.Drawing.Printing.PrintPageEventArgs) If ListView1.Visible = True Then Static LastIndex As Integer = 0 Static CurrentPage As Integer = 0 'Getting the current dpi so the textleftpad 'will be the same on a different dpi than 'the 96 i'm using. Won't make much of a difference though. Dim DpiGraphics As Graphics = Me.CreateGraphics Dim DpiX As Integer = DpiGraphics.DpiX Dim DpiY As Integer = DpiGraphics.DpiY DpiGraphics.Dispose() Dim X, Y As Integer Dim ImageWidth As Integer Dim TextRect As Rectangle = Rectangle.Empty Dim TextLeftPad As Single = CSng(4 * (DpiX / 96)) '4 pixel pad on the left. Dim ColumnHeaderHeight As Single = CSng(ListView1.Font.Height + (10 * (DpiX / 96))) '5 pixel pad on the top an bottom Dim StringFormat As New StringFormat Dim PageNumberWidth As Single = e.Graphics.MeasureString(CStr(CurrentPage), ListView1.Font).Width 'Specify the text should be drawn in the center of the line and 'that the text should not be wrapped and the text should show 'ellipsis would cut off. StringFormat.FormatFlags = StringFormatFlags.NoWrap StringFormat.Trimming = StringTrimming.EllipsisCharacter StringFormat.LineAlignment = StringAlignment.Center CurrentPage += 1 'Start the x and y at the top left margin. X = CInt(e.MarginBounds.X) Y = CInt(e.MarginBounds.Y) 'Draw the column headers For ColumnIndex As Integer = 0 To ListView1.Columns.Count - 1 TextRect.X = X TextRect.Y = Y TextRect.Width = ListView1.Columns(ColumnIndex).Width TextRect.Height = ColumnHeaderHeight e.Graphics.FillRectangle(Brushes.LightGray, TextRect) e.Graphics.DrawRectangle(Pens.DarkGray, TextRect) 'TextLeftPad adds a little padding from the gridline. Add it to the left and subtract it from the right. TextRect.X += TextLeftPad TextRect.Width -= TextLeftPad e.Graphics.DrawString(ListView1.Columns(ColumnIndex).Text, ListView1.Font, Brushes.Black, TextRect, StringFormat) 'Move the x position over the width of the column width. Since I subtracted some padding add the padding back when offsetting. X += TextRect.Width + TextLeftPad Next 'Just drew the headers. Move the Y down the height of the column headers.

ImageWidth = 0 If ListView1.SmallImageList IsNot Nothing Then 'If the image key is set then draw the image with the key . If not draw the image with the index. A tiny bit of validation would be good. If Not String.IsNullOrEmpty(.ImageKey) Then e.Graphics.DrawImage(ListView1.SmallImageList.Images(.ImageKey), X, Y) ElseIf .ImageIndex >= 0 Then e.Graphics.DrawImage(ListView1.SmallImageList.Images(.ImageIndex), X, Y) End If ImageWidth = ListView1.SmallImageList.ImageSize.Width End If 'Now draw the subitems. using the columns count so the grid lines can be drawn.
