A printing class for the DataGridView.

Introduction

The DataGridView control in .NET 2.0 is an amazing data representation control, and contains many advanced features that we could benefit from. The only thing that is not supported by this control is the printing feature. I searched the web for such a feature, but did not find anything really good, and most of the printing classes that I found were for printing a DataTable object or for printing the traditional DataGrid control. Therefore, I decided to create my own code for this feature and share it with others.

The Class Features

  • The print style is almost the same as the style of the DataGridView control:
    • the same font style for the header and other rows,
    • the same foreground and background styles for the header and other rows,
    • the same alternating background style for the rows,
    • special font for certain rows will be considered,
    • special foreground and background styles for certain rows will be considered,
    • the same alignment for the columns.
  • Supports multiple pages.
  • The width of each column to be printed is calculated to fit all the cells (including the header cell).
  • The title at the top of the page can be specified.
  • The title font and color could be specified.
  • The title and the header row are repeated in each page.
  • The report could be top-centered (considering the top margin of the page) on the page or be aligned to the top-left margin.
  • The printing process ignores any invisible rows or columns (assuming that the user does not want them to appear).
  • If the DataGridView width is greater than the page width, then the columns with x coordinate greater than the page width will be printed into another page. This ensures that all columns will be printed (Thanks to Stephen Long).
  • Support page numbering.
  • The printing process uses Graphics.MeasureString to calculate the height and width for a certain text with a specified font. This ensures the preciseness of the printing.
  • The class supports Right-to-Left fonts.

The Class Constructor

public DataGridViewPrinter(DataGridView aDataGridView, PrintDocument aPrintDocument,
    bool CenterOnPage, bool WithTitle, string aTitleText, Font aTitleFont,
    Color aTitleColor, bool WithPaging)
  • aDataGridView: The DataGridView control which will be printed.
  • aPrintDocument: The PrintDocument to be used for printing.
  • CenterOnPage: Determines if the report will be printed in the top-center of the page.
  • WithTitle: Determines if the page contains a title text.
  • aTitleText: The title text to be printed in each page (if WithTitle is set to true).
  • aTitleFont: The font to be used with the title text (if WithTitle is set to true).
  • aTitleColor: The color to be used with the title text (if WithTitle is set to true).
  • WithPaging: Determine if the page number will be printed.

How to Use the Class

The project should have the following global objects:

// The DataGridView Control which will be printed.
DataGridView MyDataGridView;
// The PrintDocument to be used for printing.
PrintDocument MyPrintDocument;
// The class that will do the printing process.
DataGridViewPrinter MyDataGridViewPrinter;

Then, use the following code:

// The printing setup function
private bool SetupThePrinting()
{
    PrintDialog MyPrintDialog = new PrintDialog();
    MyPrintDialog.AllowCurrentPage = false;
    MyPrintDialog.AllowPrintToFile = false;
    MyPrintDialog.AllowSelection = false;
    MyPrintDialog.AllowSomePages = false;
    MyPrintDialog.PrintToFile = false;
    MyPrintDialog.ShowHelp = false;
    MyPrintDialog.ShowNetwork = false;

    if (MyPrintDialog.ShowDialog() != DialogResult.OK)
        return false;

    MyPrintDocument.DocumentName = "Customers Report";
    MyPrintDocument.PrinterSettings = 
                        MyPrintDialog.PrinterSettings;
    MyPrintDocument.DefaultPageSettings =
    MyPrintDialog.PrinterSettings.DefaultPageSettings;
    MyPrintDocument.DefaultPageSettings.Margins = 
                     new Margins(40, 40, 40, 40);

    if (MessageBox.Show("Do you want the report to be centered on the page",
        "InvoiceManager - Center on Page", MessageBoxButtons.YesNo,
        MessageBoxIcon.Question) == DialogResult.Yes)
        MyDataGridViewPrinter = new DataGridViewPrinter(MyDataGridView,
        MyPrintDocument, true, true, "Customers", new Font("Tahoma", 18,
        FontStyle.Bold, GraphicsUnit.Point), Color.Black, true);
    else
        MyDataGridViewPrinter = new DataGridViewPrinter(MyDataGridView,
        MyPrintDocument, false, true, "Customers", new Font("Tahoma", 18,
        FontStyle.Bold, GraphicsUnit.Point), Color.Black, true);

    return true;
}
// The Print Button
private void btnPrint_Click(object sender, EventArgs e)
{            
    if (SetupThePrinting())
        MyPrintDocument.Print();
}
// The PrintPage action for the PrintDocument control
private void MyPrintDocument_PrintPage(object sender,
    System.Drawing.Printing.PrintPageEventArgs e)
{
    bool more = MyDataGridViewPrinter.DrawDataGridView(e.Graphics);
    if (more == true)
        e.HasMorePages = true;
}
// The Print Preview Button
private void btnPrintPreview_Click(object sender, EventArgs e)
{
    if (SetupThePrinting())
    {
        PrintPreviewDialog MyPrintPreviewDialog = new PrintPreviewDialog();
        MyPrintPreviewDialog.Document = MyPrintDocument;
        MyPrintPreviewDialog.ShowDialog();
    }
}

Problems With the Class

  • If a certain column's width is greater than the page width, then the excluded text will not be wrapped or printed in another page.
  • The class does not support image cells.
