ReportViewer在C＃中按下「Enter」時打印

Question

我有一個reportviewer並啓用了打印按鈕，但沒有啓用toolbar.When用戶按下輸入reportviewer應該開始printing.It應該不顯示甚至printdialog also.What代碼我應該寫在KeyPres事件？

Answer 1

This是什麼爲我工作，當我想以編程方式從ReportViewer打印。

您需要將PrintController設置爲StandardPrintController以禁止打印對話框，例如

printDoc.PrintController = new System.Drawing.Printing.StandardPrintController(); 

Answer 2

這是我在報表查看器中進行手動打印的代碼。它在VB.NET中。 它通過處理PrintDocument對象的Print Event來工作。

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

我正在爲我的項目使用自定義報告。自定義是指使用e.Graphics.DrawString類型代碼構建的報表。

所以我在PrintDocument

默認打印事件所做的所有的報告（編碼），這裏是PrintDocument關聯的工具。將它拖放到屏幕上，然後雙擊它以創建事件處理程序。

的PrintDocoument事件處理程序背後的代碼是：

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); 
     } 

    } 

終於解答你的問題。在你的表格KeyDown事件中使用這個。

private void Form_KeyDown(object sender, KeyEventArgs e) 
    { 
     if (e.KeyCode == Keys.Enter) 
     { 
      printDocument1.Print(); 
     } 
    } 

它會直接從您的打印機打印您的收據。
