Hello Everyone,

I want to add a print function to print everything( few graphs) that is displayed on tabpage.

I found this code, that supposed to convert the panel to bitmap and then print it.

however it just prints a blank sheet.

What is wrong with what im doing?

C#

Bitmap MyChartPanel = new Bitmap(panel1.Width, panel1.Height);
panel1.DrawToBitmap(MyChartPanel, new Rectangle(0, 0, panel1.Width, panel1.Height));
PrintDialog MyPrintDialog = new PrintDialog();
if (MyPrintDialog.ShowDialog() == DialogResult.OK)
    {
         System.Drawing.Printing.PrinterSettings values;
         values = MyPrintDialog.PrinterSettings;
         MyPrintDocument.PrintController = new System.Drawing.Printing.StandardPrintController();
         MyPrintDocument.Print();
    }
 MyPrintDocument.Dispose();

All you are doing is calling the Print event of the PrintDocument, without defining what method should handle the Print event. You should add something like this to your code in the if block:-

C#

MyPrintDocument.PrintPage += new PrintPageEventHandler(PrintPage);

then you define a method PrintPage which actually does the printing

C#

void PrintPage(object sender, PrintPageEventArgs e)
{
     Bitmap MyChartPanel = new Bitmap(panel1.Width, panel1.Height);  
     panel1.DrawToBitmap(MyChartPanel, new Rectangle(0, 0, panel1.Width, panel1.Height));  
     e.Graphics.DrawImage(MyChartPanel, newPoint(0,0));
}

Hope this helps
