Can not print on Single Page dgvprinter c#
If you're facing issues with printing a DataGridView (dgv) in C# and the content is not fitting onto a single page, you can adjust the print settings and page layout to ensure everything is properly displayed. Here are a few steps you can follow:
Set the PrintDocument's DefaultPageSettings:
csharpPrintDocument printDocument = new PrintDocument();
printDocument.DefaultPageSettings.Landscape = false; // Set to true if you want a landscape layout
This step sets the page orientation to either portrait (default) or landscape mode based on your requirement.
Handle the PrintDocument's PrintPage event:
csharpprivate void printDocument_PrintPage(object sender, PrintPageEventArgs e)
{
DataGridView dgv = dataGridView1; // Replace with your DataGridView object
DataGridViewPrinter printer = new DataGridViewPrinter(dgv, e.Graphics, e.MarginBounds, e.PageBounds);
bool morePages = printer.DrawDataGridView();
if (morePages)
e.HasMorePages = true;
}
Here,
dataGridView1
should be replaced with the name of your DataGridView object. The code uses a custom DataGridViewPrinter class (explained in the next step) to draw the contents of the DataGridView onto the PrintPage event's Graphics object. It also handles the possibility of multiple pages, setting theHasMorePages
property accordingly.Implement the DataGridViewPrinter class:
csharppublic class DataGridViewPrinter
{
// Define the required constructor and methods to handle printing the DataGridView
// Refer to the following link for an example implementation:
// https://docs.microsoft.com/en-us/dotnet/desktop/winforms/advanced/how-to-print-a-windows-forms-datagridview-control?view=netframeworkdesktop-4.8
}
You'll need to implement the DataGridViewPrinter class to handle the printing logic. Microsoft provides an example implementation in their official documentation, which you can refer to for a detailed guide on how to print a DataGridView: How to: Print a Windows Forms DataGridView Control
By adjusting the print settings and using a custom DataGridViewPrinter class, you can ensure that the contents of the DataGridView are properly printed on a single page or across multiple pages as needed.
