Printing in C# (wpf)

Printing in WPF is both simple and not so simple.

It starts with basically with one or two lines of code you are printing already.

private void PrintBtn_Click(object sender, RoutedEventArgs e)
{
    PrintDialog printDialog = new PrintDialog();
    if (printDialog.ShowDialog() == true)
    {
    printDialog.PrintVisual(grid, "My First Print Job");
    }
}

However, pagination in WPF is not done with a single line of code. Then you get into FlowDocuments and similar more advanced topics.

If you are making a non-commercial tool for yourself, consider iTextSharp which is very good too.

If you want to print all records from datagrid in WPF.In which I have create flow document using code you can understand logic and make it according to own requirement.After a lot of working.I have done code recently.It is tested code.It will print every datagrid with all records.It is easy and simple code.You would add a class.If you want to decorate a datagrid then go to PrintDG class then decorate it acording to own requirement.
Follow these steps.
Step1:Add these references on top.

 using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Media;

Step2: Add class PrintDG.cs.

  public  class PrintDG
{
         public void printDG(DataGrid dataGrid, string title)
    {



        PrintDialog printDialog = new PrintDialog();
        if (printDialog.ShowDialog() == true)
        {
            FlowDocument fd = new FlowDocument();

            Paragraph p = new Paragraph(new Run(title));
            p.FontStyle = dataGrid.FontStyle;
            p.FontFamily = dataGrid.FontFamily;
            p.FontSize = 18;
            fd.Blocks.Add(p);

            Table table = new Table();
            TableRowGroup tableRowGroup = new TableRowGroup();
            TableRow r = new TableRow();
            fd.PageWidth = printDialog.PrintableAreaWidth;
            fd.PageHeight = printDialog.PrintableAreaHeight;
            fd.BringIntoView();

            fd.TextAlignment = TextAlignment.Center;
            fd.ColumnWidth = 500;
            table.CellSpacing = 0;

            var headerList = dataGrid.Columns.Select(e => e.Header.ToString()).ToList();


            for (int j = 0; j < headerList.Count; j++)
            {

                r.Cells.Add(new TableCell(new Paragraph(new Run(headerList[j]))));
                r.Cells[j].ColumnSpan = 4;
                r.Cells[j].Padding = new Thickness(4);

                r.Cells[j].BorderBrush = Brushes.Black;
                r.Cells[j].FontWeight = FontWeights.Bold;
                r.Cells[j].Background = Brushes.DarkGray;
                r.Cells[j].Foreground = Brushes.White;
                r.Cells[j].BorderThickness = new Thickness(1, 1, 1, 1);
            }
            tableRowGroup.Rows.Add(r);
            table.RowGroups.Add(tableRowGroup);
            for (int i = 0; i < dataGrid.Items.Count; i++)
            {

                DataRowView row = (DataRowView)dataGrid.Items.GetItemAt(i);

                table.BorderBrush = Brushes.Gray;
                table.BorderThickness = new Thickness(1, 1, 0, 0);
                table.FontStyle = dataGrid.FontStyle;
                table.FontFamily = dataGrid.FontFamily;
                table.FontSize = 13;
                tableRowGroup = new TableRowGroup();
                r = new TableRow();
                for (int j = 0; j < row.Row.ItemArray.Count(); j++)
                {

                    r.Cells.Add(new TableCell(new Paragraph(new Run(row.Row.ItemArray[j].ToString()))));
                    r.Cells[j].ColumnSpan = 4;
                    r.Cells[j].Padding = new Thickness(4);

                    r.Cells[j].BorderBrush = Brushes.DarkGray;
                    r.Cells[j].BorderThickness = new Thickness(0, 0, 1, 1);
                }

                tableRowGroup.Rows.Add(r);
                table.RowGroups.Add(tableRowGroup);

            }
            fd.Blocks.Add(table);

            printDialog.PrintDocument(((IDocumentPaginatorSource)fd).DocumentPaginator, "");

        }
    }

}

Step2: Then go to print button click event and create object of PrintDG class then call printDG pass to It two parameters datagridname and title.
Like :

private void print_button_Click(object sender, RoutedEventArgs e)
    {
            PrintDG print = new PrintDG();

 print.printDG(datagridName, "Title");
}

If any erorr occure during execution tell me I will solve It.The is running code only you copy and past.
