WPF - print datagrid contents

I Have looked around and I have not found a solid answeer to this question. I am trying to print my datagrid content when I press a button, the main problem is that my datagrid has too much data and only whatever is shown in the screen is printing. I need It to print all data and if the data does not fit in current page create a mew page and print the rest.

Here is my solution printing Data Grid View using System.Drawing.Printing
using System.Drawing.Printing;
private int PageCounter { get; set; } = 1;
private int RowCounter { get; set; }
Print Button
private void BtnPrint_Click(object sender, EventArgs e)
{
PrintDocument printDoc = new PrintDocument();
IQueryable<PaperSize> paperSizes = printDoc.PrinterSettings.PaperSizes.Cast<PaperSize>().AsQueryable();
printDoc.DefaultPageSettings.PaperSize = paperSizes.First(ps => ps.Kind == PaperKind.A4);
printDoc.DefaultPageSettings.Margins = new Margins(0, 0, 0, 0);
pageCounter = 1;
printDoc.PrintPage += PrintDoc_PrintPage;
printDoc.Print();
}

Print on specific coordinates

I have a card that has10cm height and 15cm width. I am trying to print a string on the following coordinates: 1,5cm from top to bottom and 3,5cm from the left to right. Until now i tried to use the bellow code that i found on msdn but with no luck. The code that i am using is :

How to Print images on paper using PrintDocument

My problem is that is that my code prints the images overlapping each other. I do not know how to change the x and y positions. The printer should print 3 images per row and then move to the next row.

Desired output :
I am getting :
As you can see the last digit is overlapping. I want to draw it next to the previous one

I have observed the code and found the issue.. in panel1_print u are not incrementing the values properly..
I have made the required changes now u will get the 4 bar in a line and 5th one in another line - check the attached image.
just replace ur panel1_Paint with this new code thats it you can find the changes..
I have marked them as
//start changes by Deepak
..
..
..
//end changes by Deepak
and also declare two variables loopValX and loopValY as int
here is the code..

You Should do it with the help of a DataGridView (That Contains Images in a Column).
The Images Will Then Print in each new row or column (by modifying as your desire)
The Following Class will do your work by passing it the whole DataGridView And Header in its constructor.

Your position variables are being declared inside the loop, meaning that they are reset for each pass through the loop. Keep position variables for X and Y outside of the loop over serial and adjust it for the total width (and height, if you start a new row of barcodes) of each barcode.

Getting exception "Parameter is not valid" when minimizing the form to the taskbar

It happen only when I resize the form when the program is running.
I click the "-" and the program is minimised to the taskbar, then I see the error/exception message.

I had the same problem, with a huge list of errors in the Just-In-Time-Debugger. After several hours of searching I found my own way. Try this, no more exceptions!!

//check if form is minimized, and you know that this method is only called if and only if the form get a change in size, meaning somebody clicked in the taskbar on your application

Thumb up!
