使用C#打印网格视图数据 [英] print gird view data using c#

问题描述

嗨 我已经在网格中显示了数据类别和学生人数，
我想添加一个按钮，单击该按钮时，我想通过打印机从该数据中取出打印内容，

我已经看到许多将这些数据转换为图像的代码，但是我想要的数据就像在excell中打印的一样，包括单元格边框.

谁能帮助我

解决方案

我不是专家，但是...使用Crystal Report或Microsoft Report Viewer可能会帮助您.

您可以使用以下C#代码将任何SQL表数据(此处为班级和学生人数)导出到excel工作表中.在此之前，您必须添加MICROSOFT OFFICE EXCEL 12.0的COM参考. /> 这是用于将sql数据导出到excel的常规代码.

Hi...
You can export any of your SQL table data(here class and no. of students in ur case) into an excel sheet by using the following C# code.Before doing this, you have to add COM reference for MICROSOFT OFFICE EXCEL 12.0 .
This is a general code for exporting sql data to excel.

using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Data.Sql;
using System.Data.SqlClient;
using Microsoft.Office.Interop.Excel;

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{


}

// In your Button click event

protected void Button1_Click(object sender, EventArgs e)
{
try
{
string constr = "YOUR CONNECTION STRING";

SqlConnection conn = new SqlConnection(constr);
conn.Open();
SqlCommand command = new SqlCommand("select * from table_name", conn);
DataSet dataset = new DataSet();
SqlDataAdapter adapter = new SqlDataAdapter(command);
adapter.Fill(dataset);
Microsoft.Office.Interop.Excel.ApplicationClass excel = new ApplicationClass();
excel.Application.Workbooks.Add(true);
System.Data.DataTable table = dataset.Tables[0];
int ColumnIndex = 0;
foreach (System.Data.DataColumn col in table.Columns)
{
ColumnIndex++;
excel.Cells[1, ColumnIndex] = col.ColumnName;
}
int rowIndex = 0;
foreach (DataRow row in table.Rows)
{
rowIndex++;
ColumnIndex = 0;
foreach (DataColumn col in table.Columns)
{
ColumnIndex++;
excel.Cells[rowIndex + 1, ColumnIndex] = row[col.ColumnName];
}
}
excel.Visible = true;
Worksheet worksheet = (Worksheet)excel.ActiveSheet;
worksheet.Activate();
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
}
}
