I have an issue regarding printing multiple pages using the code below. It always prints only the last page. Can you guys please help me?
using (var rasterizer = new PdfRasterizer(pdfInputPdf))
{
// Create a JpegImageFormat object.
var jpegImageFormat = new JpegImageFormat(100);
// Create a FixedImageSize object with required width and height.
var imageSize = new PercentageImageSize(400);
// Save the image.
var imageData = rasterizer.Draw(jpegImageFormat, imageSize);
using (var pd = new PrintDocument())
{
var margins = new Margins(0, 40, 0, 40);
pd.DefaultPageSettings.Margins = margins;
pd.DefaultPageSettings.Color = true;
pd.DefaultPageSettings.Landscape = false;
pd.PrintPage += (sender, args) =>
{
PrintPage(text1, text2, imageData, pd, args);
};
pd.Print();
}
}
And this class:
private static int counter = 0;
private static void PrintPage(string text1, string text2, byte[][] imageData, PrintPageEventArgs args)
{
foreach (var b in imageData)
{
using (var stream = new MemoryStream(b))
{
var i = Image.FromStream(stream);
CreateNotApprovedWatermark(i, text1, text2);
if (args.PageSettings.PrinterSettings.CanDuplex)
{
args.PageSettings.PrinterSettings.Duplex = Duplex.Horizontal;
}
var m = args.MarginBounds;
if (i.Width / (double)i.Height > m.Width / (double)m.Height) // image is wider
{
m.Height = (int)(i.Height / (double)i.Width * m.Width);
}
else
{
m.Width = (int)(i.Width / (double)i.Height * m.Height);
}
args.Graphics.DrawImage(i, m);
if (counter <= 2)
{
counter++;
args.HasMorePages = true;
}
else
{
args.HasMorePages = false;
}
}
}
}
I found a easy solution to my problem after quit some trial and error:
using (var rasterizer = new PdfRasterizer(new Foxit.PDF.Rasterizer.InputPdf(pdfData)))
{
// Create a JpegImageFormat object.
var jpegImageFormat = new JpegImageFormat(100);
// Create a FixedImageSize object with required width and height.
var imageSize = new PercentageImageSize(400);
// Save the image.
var imagePages = rasterizer.Draw(jpegImageFormat, imageSize);
using (var pd = new PrintDocument())
{
var margins = new Margins(0, 40, 0, 40);
pd.DefaultPageSettings.Margins = margins;
pd.DefaultPageSettings.Color = true;
pd.DefaultPageSettings.Landscape = false;
var pageNumber = 0;
pd.PrintPage += (sender, args) =>
{
PrintPage(pageNumber, text1, text2, imagePages[pageNumber], args);
if (pageNumber < imagePages.Count())
{
pageNumber++;
args.HasMorePages = pageNumber != imagePages.Count();
}
};
pd.Print();
}
}
The problem was placement of the HasMorePages property.

I am making a software to help me at work. It reads two excel (xlsx) files and get some info from them. Then it put the info in one of the two datagridviews or in both datagridviews.
Then i have a number that i need to show when i print the datagridviews. In print preview all is exactly as i want but when printing on paper it removes (or doesn't remember) everything about first datagridview and anything i print with it and start from the 2nd datagridview.
Here how it shows in print preview:
but when i print it on paper i get like this
Why the first datagridview gone on paper but if i print it PDF from Microsoft print to PDF i get PDF that has exactly as the preview.
Problem only when printing on paper.
Here is my printing code https://pastebin.com/6ZF2FevZ

I found the problem.
If i print it by print dialog it prints good. But when i show the preview, this problem happens. Because i didn't set dgv1Finished to false on OnBeginPrint.
when it actually prints It runs the code again and dgv1Finished is already true after the preview so it get datagridview2 first and nothing about datagridvie1.
I only have to set dgv1Finished = false in OnBeginPrint and now it prints everything.
I have C# project already done but im having issue with printing it's charts when comes out with more pages of data points, i got the scroll bar work when start getting more pages so the user can review all data on all pages but i could not find how to make the print preview shows them or print them,
when click on print, it shows only the first page on the print preview and same thing when print it out.
her is the print code:
PrintPreviewDialog ppd = new PrintPreviewDialog();
ppd.Document = this.chart1.Printing.PrintDocument;
((Form)ppd).WindowState = FormWindowState.Maximized;
chart1.Printing.PrintDocument.DefaultPageSettings.Landscape = true;
chart1.Printing.PrintDocument.DefaultPageSettings.Margins.Left = 0;
chart1.Printing.PrintDocument.DefaultPageSettings.Margins.Right = 0;
chart1.Printing.PrintDocument.DefaultPageSettings.Margins.Top = 0;
chart1.Printing.PrintDocument.DefaultPageSettings.Margins.Bottom = 0;
ppd.ShowDialog();
and here is the chart load code:
public void loadChart(string sqlvalue)//load chart method
{
chart1.ChartAreas[0].AxisY.Maximum = 55;
chart1.ChartAreas[0].AxisY.Minimum = 35;
chart1.ChartAreas[0].AxisY.Interval = 5;//control how many lines/Interval
chart1.ChartAreas[0].AxisY.ScrollBar.Enabled = true;
chart1.ChartAreas[0].AxisY.ScaleView.Zoomable = true;
chart1.ChartAreas[0].AxisX.Minimum = 0;
// chart1.ChartAreas[0].AxisX.Maximum = 10;
chart1.ChartAreas[0].AxisX.Interval = 1;
//X AXES label angle
chart1.ChartAreas[0].AxisX.LabelStyle.Angle = 60;
da = new SqlDataAdapter(sqlvalue, cn.connect());
da.Fill(dt);
this.chart1.DataSource = dt;
this.chart1.Series["left"].XValueMember = dt.Columns[3].ToString();//date data
this.chart1.Series["left"].YValueMembers = dt.Columns[1].ToString();//spindle 1 data
this.chart1.Series["Right"].YValueMembers = dt.Columns[2].ToString();//spindle 2 data
//label the series lines, Backcolor and forcolor
chart1.Series[0].LabelBackColor = Color.Red;

//datapoint marker's color, bordercolor,style and size
chart1.Series[0].MarkerColor = Color.White;
chart1.Series[0].MarkerBorderColor = Color.Black;
chart1.Series[0].MarkerStyle = MarkerStyle.Circle;
chart1.Series[0].MarkerSize = 8;
//datapoint marker's color, style and size
chart1.Series[1].MarkerColor = Color.White;
chart1.Series[1].MarkerBorderColor = Color.Black;
chart1.Series[1].MarkerStyle = MarkerStyle.Circle;
chart1.Series[1].MarkerSize = 8;
chart1.Series[1].LabelBackColor = Color.Blue;
chart1.Series[1].LabelForeColor = Color.White;
//Chart background lines color
chart1.ChartAreas[0].AxisX.MajorGrid.LineColor = Color.Silver;
chart1.ChartAreas[0].AxisY.MajorGrid.LineColor = Color.Silver;
this.chart1.DataBind();
cn.disconnect();
// enable autoscroll
chart1.ChartAreas[0].CursorX.AutoScroll = true;//------------
chart1.ChartAreas[0].AxisX.ScaleView.Zoomable = true;
chart1.ChartAreas[0].AxisX.ScaleView.Zoom(0, 15);
chart1.ChartAreas[0].AxisX.ScrollBar.ButtonStyle = ScrollBarButtonStyles.SmallScroll;
// set scrollbar small change to the target size
chart1.ChartAreas[0].AxisX.ScaleView.SmallScrollSize = 15;
Legend left = new Legend();
Legend LC = CustomCloneLegend(chart1, left);
chart1.Legends.Add(LC);
chart1.Padding = Padding.Empty;
ChartArea CA = chart1.ChartAreas[0];
CA.Position = new ElementPosition(4,6, 100, 90);
}
Thank you for your time and help, here is the chart code update:
private static Image MergeImages(List<Image> imageList)
{
var finalSize = new Size();
foreach (var image in imageList)
{
if (image.Width > finalSize.Width)
{
finalSize.Width = image.Width;
}
finalSize.Height += image.Height;
}
var outputImage = new Bitmap(finalSize.Width, finalSize.Height);
using (var gfx = Graphics.FromImage(outputImage))
{
var y = 0;
foreach (var image in imageList)
{
gfx.DrawImage(image, 0, y);
y += image.Height;
}
}
return outputImage;
}
The second method:
List<Image> ChartsToImages(List<Chart> charts)
{
var imageList = new List<Image>();
foreach (var c in charts)
{
using (var ms = new MemoryStream())
{
c.SaveImage(ms, ChartImageFormat.Png);
var bmp = System.Drawing.Bitmap.FromStream(ms);
imageList.Add(bmp);
}
}
return imageList;
}
and this code
var chartList = new List<Chart> { chart1 };
var imageList = ChartsToImages(chartList);
var finalImage = MergeImages(imageList);
finalImage.Save("D:\\Junk.png", ImageFormat.Png);
Im not sure is that what you mean by your first comment, but i found this code here under Converting chart to image questions. this code convert and saves the chart in the same amount of pages but i need to show them in the printpreviewcontrol and print them.
Below code refers to the as per page count starting point and ending point based printing. And Grid view value chars are row loop based counting the page.
private int numberOfItemsPerPage = 0;
private int numberOfItemsPrintedSoFar = 0;
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{

for (int l = numberOfItemsPrintedSoFar; l < dataGridView2.Rows.Count; l++)
{
numberOfItemsPerPage = numberOfItemsPerPage + 1;
if (numberOfItemsPerPage <= 25) // 25 is Page Line Item
{
numberOfItemsPrintedSoFar++;
if (numberOfItemsPrintedSoFar <= dataGridView2.Rows.Count)
{
height += dataGridView2.Rows[0].Height;

We have started a project for printing, however we are completely stuck when it comes to telling the printer what paper size is selected.
Everytime we select the paper size and hit print, the printer preview is showing A4 everytime and not our selected size although if we open the print preferences the correct size is selected.

I expect if we select A5, it tells the print driver to print A5,
If we select a custom "user defined" paper size, it tells the printer which size is selected. And not fixing this at A4 everytime
We cant seem to set the paper size outside the print dialog.
I believe; following this and this MSDN article; you are going to want to do something along the lines of:
System.Drawing.Printing.PaperSize paperSize = new System.Drawing.Printing.PaperSize("custom", width, height);
PrintDocument printDoc = new PrintDocument();
printDoc.DefaultPageSettings.PaperSize = paperSize;
I have walk through your code,
I think some event raise by front end (XAML) on specific use cases that is the overriding the actual value in "Properties.Settings.Default."
It would be better to resolve if you provide a XAML code for this issue.
I can look into it and will give you better solution.
You can share me code here is my skype : shsakariya

If I invoke the first method(use real file on the disk), it's ok, I can insert my picture into excel file. But if I read the file into memorystream and invoke method2, I can see the picture rectangle with error message.
So my question is how can I insert picture into excel via memorystream? Because I won't create too many files on disk.
I believe you need to create bitmap image data from stream first
There's a solution already for that here on Stack Overflow: Byte Array to Bitmap Image
I copy-paste the code from the solution:
int w= 100;
int h = 200;
int ch = 3; //number of channels (ie. assuming 24 bit RGB in this case)
byte[] imageData = new byte[w*h*ch]; //you image data here
Bitmap bitmap = new Bitmap(w,h,PixelFormat.Format24bppRgb);
BitmapData bmData = bitmap.LockBits(new System.Drawing.Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadWrite, bitmap.PixelFormat);
IntPtr pNative = bmData.Scan0;
Marshal.Copy(imageData,0,pNative,w*h*ch);
bitmap.UnlockBits(bmData);
OK, I think I have found solution.
I change memorystream parameter to string, and convert it to memorystream like below:
MemoryStream ms = new System.IO.MemoryStream(System.Convert.FromBase64String(str))
Now, it works.
I learn it from open xml sdk 2.5 productivity tool.
In tableview cell I am dynamically showing some messages and images,If i am having more images
showing in horizontal scroll. now what my task is Clicking on particular image need to show that image in full page view, i have done the code, but my problem is clicking on any image showing last image in full view.
