我有一个reportviewer并启用了打印按钮但没有启用工具栏。当用户按下enter reportviewer应该开始打印。它甚至不应该显示printdialog。我应该在KeyPres事件中写什么代码？

This对我有用。
您需要将PrintController设置为StandardPrintController以禁止打印对话框，例如
printDoc.PrintController = new System.Drawing.Printing.StandardPrintController();

以下是我在报告查看器中手动打印的代码。它在VB.NET中。 它的工作原理是处理PrintDocument对象的Print Event。
Dim m_pageSettings As PageSettings 'Stores page settings for printout
Dim m_currentPage As Integer 'Used for index of pages
Private m_pages As New List(Of Stream)() 'Stores a stream for each pages
'Event fires when printDocument starts printing - reset page index to zero
Private Sub PrintDocument1_BeginPrint(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintEventArgs) Handles PrintDocument1.BeginPrint
m_currentPage = 0
End Sub
'Function that prints all the pages included in the report
Private Sub PrintDocument1_PrintPage(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
Dim pageToPrint As Stream = m_pages(m_currentPage)
pageToPrint.Position = 0
Dim pageMetaFile As Metafile = New Metafile(pageToPrint) 'create an image(metafile) of the report page
Using (pageMetaFile)
'Create a rectangle the size of our report - include margins
' Dim adjustedRect As Rectangle = New Rectangle( _
' e.PageBounds.Left - CType(e.PageSettings.HardMarginX, Integer), _
' e.PageBounds.Top - CType(e.PageSettings.HardMarginY, Integer), _
' e.PageBounds.Width, _
' e.PageBounds.Height)
Dim adjustedRect As Rectangle = New Rectangle( _
e.PageBounds.Left, _
e.PageBounds.Top, _
e.PageBounds.Width, _
e.PageBounds.Height)
e.Graphics.FillRectangle(Brushes.White, adjustedRect) 'Fill rectangle with WHITE background
e.Graphics.DrawImage(pageMetaFile, adjustedRect) 'Draw report in rectangle - this will be printed
m_currentPage = m_currentPage + 1
e.HasMorePages = m_currentPage < m_pages.Count 'If more pages are left - keep processing
End Using
End Sub
'Event fires when PrintDocument queries for PageSettings. Return a copy of m_pagesettings.
Private Sub PrintDocument1_QueryPageSettings(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.QueryPageSettingsEventArgs) Handles PrintDocument1.QueryPageSettings
e.PageSettings = CType(m_pageSettings.Clone, PageSettings)
End Sub
'Render the report in a EMF - This function creates metafiles(images) of each page in the report
Private Sub RenderAllLocalReportPages(ByVal localReport As LocalReport)
Dim deviceInfo As String = CreateEMFDeviceInfo() 'Enhanced MetaFile
Dim warnings As Warning() = Nothing
localReport.Render("IMAGE", deviceInfo, AddressOf LocalReportCreateStreamCallback, warnings)
End Sub
'Callback function used with RenderAllLocalReportPages
Private Function LocalReportCreateStreamCallback(ByVal name As String, ByVal extension As String, ByVal encoding As Encoding, ByVal mimeType As String, ByVal willSeek As Boolean) As Stream
Dim stream As New MemoryStream()
m_pages.Add(stream)
Return stream
End Function
Private Function CreateEMFDeviceInfo() As String
Dim paperSize As PaperSize = m_pageSettings.PaperSize
Dim margins As Margins = m_pageSettings.Margins
'The device info string defines the page range to print as well as the size of the page.
'A start and end page of 0 means generate all pages.
Return String.Format(CultureInfo.InvariantCulture, "<DeviceInfo><OutputFormat>emf</OutputFormat><StartPage>0</StartPage><EndPage>0</EndPage><MarginTop>{0}</MarginTop><MarginLeft>{1}</MarginLeft><MarginRight>{2}</MarginRight><MarginBottom>{3}</MarginBottom><PageHeight>{4}</PageHeight><PageWidth>{5}</PageWidth></DeviceInfo>", ToInches(margins.Top), ToInches(margins.Left), ToInches(margins.Right), ToInches(margins.Bottom), ToInches(paperSize.Height), ToInches(paperSize.Width))
End Function
'Convert report printing size to inches
Private Shared Function ToInches(ByVal hundrethsOfInch As Integer) As String
Dim inches As Double = hundrethsOfInch / 100.0R
Return inches.ToString(CultureInfo.InvariantCulture) & "in"
End Function

我正在为我的项目使用自定义报告。自定义表示使用e.Graphics.DrawString类型代码构建的报告。
所以我在PrintDocument
这是PrintDocument工具的。将其拖放到屏幕上，然后双击它以创建事件处理程序。
PrintDocoument的事件处理程序背后的代码是：
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
Image image = Properties.Resources.New_Header;
Font font = new Font("Arial", 7, FontStyle.Bold);
Font font2 = new Font("Arial", 7, FontStyle.Regular);
float fontHeight = font2.GetHeight();
e.Graphics.DrawImage(image, 20, 5, 260, 130);
e.Graphics.DrawString("Date:" + DateTime.Now.ToShortDateString(), new Font("Arial", 7, FontStyle.Bold), Brushes.Black, new Point(20, 160));
e.Graphics.DrawString("Invoice#: "+InvoiceNoTextBox.Text, new Font("Arial", 7, FontStyle.Bold), Brushes.Black, new Point(160, 160));
e.Graphics.DrawString("Client Name: " + ClientNameTextBox.Text.Trim(), new Font("Arial", 7, FontStyle.Bold), Brushes.Black, new Point(20, 180));
e.Graphics.DrawString("______________________________",
new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(20, 190));
e.Graphics.DrawString("Product", new Font("Arial", 7, FontStyle.Bold), Brushes.Black, new Point(23, 220));
e.Graphics.DrawString("U/Price", new Font("Arial", 7, FontStyle.Bold), Brushes.Black, new Point(170, 220));
e.Graphics.DrawString("Qty", new Font("Arial", 7, FontStyle.Bold), Brushes.Black, new Point(210, 220));
e.Graphics.DrawString("Total", new Font("Arial", 7, FontStyle.Bold), Brushes.Black, new Point(240, 220));
e.Graphics.DrawString("______________________________",
new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(20, 220));
int CurrentX = 25;
int CurrentY = 230;
int offset = 20;
foreach (var i in shoppingCart)
{
e.Graphics.DrawString(i.ItemName, new Font("Arial", 7, FontStyle.Regular), Brushes.Black, new Point(CurrentX, CurrentY+offset));
e.Graphics.DrawString(i.UnitPrice.ToString(), new Font("Arial", 7, FontStyle.Regular), Brushes.Black, new Point(180, CurrentY + offset));
e.Graphics.DrawString(i.Quantity.ToString(), new Font("Arial", 7, FontStyle.Regular), Brushes.Black, new Point(215, CurrentY + offset));
e.Graphics.DrawString(i.TotalPrice.ToString(), new Font("Arial", 7, FontStyle.Regular), Brushes.Black, new Point(240, CurrentY + offset));
offset = offset + (int)fontHeight + 5;
}
CurrentY = CurrentY+offset;
e.Graphics.DrawString("______________________________",
new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(20, CurrentY-5));
e.Graphics.DrawString("Total Amt: Rs." + TotalAmountTextBox.Text, new Font("Arial", 7, FontStyle.Regular), Brushes.Black, new Point(180, CurrentY + 35));
e.Graphics.DrawString("Discount%: " + DiscountTextBox.Text.Trim()+"%", new Font("Arial", 7, FontStyle.Regular), Brushes.Black, new Point(180, CurrentY + 50));
e.Graphics.DrawString("Discount: Rs." + JustDiscountTextBox.Text.Trim(), new Font("Arial", 7, FontStyle.Regular), Brushes.Black, new Point(180, CurrentY + 65));
e.Graphics.DrawString("Grand Total: Rs." + TotalToPayTextBox.Text, new Font("Arial", 7, FontStyle.Regular), Brushes.Black, new Point(180, CurrentY + 80));
e.Graphics.DrawString("Advance: Rs." + AdvancePaymentTextBox.Text.Trim(), new Font("Arial", 7, FontStyle.Regular), Brushes.Black, new Point(20, CurrentY + 95));
e.Graphics.DrawString("Cash: Rs." + givenCash.Text.Trim(), new Font("Arial", 7, FontStyle.Regular), Brushes.Black, new Point(180, CurrentY + 95));
e.Graphics.DrawString("Pending: Rs." + PendingPaymentTextBox.Text, new Font("Arial", 7, FontStyle.Regular), Brushes.Black, new Point(20, CurrentY + 110));
e.Graphics.DrawString("Return: Rs." + ReturnTextBox.Text, new Font("Arial", 7, FontStyle.Regular), Brushes.Black, new Point(180, CurrentY + 110));
e.Graphics.DrawString("Software Provided By Muhammad Abbas", new Font("Arial", 7, FontStyle.Regular), Brushes.Black, new Point(20, CurrentY + 125));
e.Graphics.DrawString("Mob:0304-9550308", new Font("Arial", 7, FontStyle.Regular), Brushes.Black, new Point(20, CurrentY + 140));
}
private void PrintPreviewButton_Click(object sender, EventArgs e)
{
try
{
printPreviewDialog1.Document = printDocument1;
printPreviewDialog1.ShowDialog();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
最后你的回答问题。在表单KeyDown活动中使用此功能。
private void Form_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
printDocument1.Print();
}
}
它将直接从您的打印机打印收据。
