网格未打印内容

按钮位于第二个网格中。第一个网格包含我要打印的内容然而，当我打印第一个网格时，它没有显示任何内容，并且正在打印一个空白文档

按钮和网格代码：

        Button Print = new Button();
        Print.Content = "Print";
        Print.Click += new RoutedEventHandler(OnPrintClick);
        secondGrid.Children.Add(Print);
        Grid.SetColumn(Print, 2);
        Grid.SetRow(Print, 5);
        ColumnDefinition myColumsecondGrid = new ColumnDefinition();
            RowDefinition myRowsecondGrid = new RowDefinition();

           myRowsecondGrid.Height = new GridLength(300);
             myColumsecondGrid.Width = new GridLength(165);

             secondGrid.ColumnDefinitions.Add(new ColumnDefinition() { Width = myColumsecondGrid.Width });
             secondGrid.RowDefinitions.Add(new RowDefinition() { Height = myRow.Height });

按钮打印代码：

                 private void OnPrintClick(object sender, RoutedEventArgs e)
      {
        PrintDialog printDlg = new System.Windows.Controls.PrintDialog();


        if (printDlg.ShowDialog() == true)
        {
            //System.Printing
            //get selected printer capabilities
           System.Printing.PrintCapabilities capabilities = printDlg.PrintQueue.GetPrintCapabilities(printDlg.PrintTicket);

            //get the size of the printer page
            Size sz = new Size(capabilities.PageImageableArea.ExtentWidth, capabilities.PageImageableArea.ExtentHeight);
            // update the layout of the visual to the printer page size.
            myGrid.Measure(sz);
            myGrid.Arrange(new Rect(new Point(capabilities.PageImageableArea.OriginWidth, capabilities.PageImageableArea.OriginHeight), sz));
            //now print the visual to printer to fit on the one page.
            //printDlg.PageRangeSelection(printQty);
            //now print the visual to printer to fit on the one page.
            String printerName = "PDF reDirect v2";
            System.Printing.PrintQueue queue = new System.Printing.LocalPrintServer().GetPrintQueue(printerName);
            printDlg.PrintQueue = queue;


            printDlg.PrintVisual(myGrid, "");
        }

    }

也许这个问题会对你有所帮助。你可以看看Measure和Arrange方法，可能在里面。

打印在wpf 中动态生成的网格

这段代码为您打印了什么吗？如果是这样的话，那就说明测量结果有问题。另外，不要忘记，在您尝试使用PrintVisual方法打印网格时，必须对其进行渲染。

PrintDialog dialog = new PrintDialog();
if (dialog.ShowDialog() == true)
{
    dialog.PrintVisual(myGrid, "CustomDescription");
}
