c＃中的数据网格视图 [英] data grid view in c#

问题描述

我编写代码以在datagridview中打印数据作为报告，这是代码：

i write code to print the data in datagridview as a report ,this is the code:

 private void timer1_Tick(object sender, EventArgs e)
        {
            string time = DateTime.Now.Hour + ":" + DateTime.Now.Minute
                                        + ":" + DateTime.Now.Second;

            if (time == "23:18:10")
            {
PrintDocument document = new PrintDocument();
                document.PrintPage += this.PrintPage;

         
                    document.Print();
            }}
        
            private void PrintPage(object sender, PrintPageEventArgs e) {
            using(Font font = new Font("Lucida Console",30)){
                e.Graphics.DrawString(@@@ how can i call the data from datagridview@@, 
                    font, 
                    Brushes.Blue,
                    e.PageBounds.Left, 
                    e.PageBounds.Top);
            }
        }

问题是如何在该代码中调用datagridview？在该代码中看到此标记@@@

the problem is how can i call the datagridview in that code? see this mark @@@ in that code

推荐答案

以下是一种方法。



通过选择列和行来打印DataGridView [ ^ ]

Below is one way of doing it.

DataGridView Printing by Selecting Columns and Rows[^]

您应该使用DataGrid的源打印报告，而不是从DataGrid中提取数据。请参阅类似的文章：使用C＃< Crystal Report with DataSet and DataTable [ ^ ]

Instead of extracting data from DataGrid, you should use the source of DataGrid print the report. See a similar article : Crystal Report with DataSet and DataTable using C#[^]
