HOW TO EXPORT DATA FROM GRIDVIEW TO EXCEL FILE USING C# WINDOWS APPLICATION
In this post, I am going to explain and demonstrate how to export data from DataGridView to Excel file using C# Windows application.
1. Design your form by placing a DataGridView control on it. Here I have designed it like this:
2. Next we will load the data into dataGridView1 using the method:
public void LoadGridData()
{
DataTable dt = new DataTable();
dt.Columns.Add("Name");
dt.Columns.Add("Address");
dt.Columns.Add("Mobile");
dt.Rows.Add("Ravi Kumar Soni", "Transport Department", "82690884xx");
dt.Rows.Add("Vikash Singh Chandel", "NIC", "82690482xx");
dataGridView1.DataSource = dt;
}
3. And finally assign values in data table values looks like this:
4. Next we add a reference to the Microsoft.Office.Interop DLL to our project from "Project" -> "Add Reference".
5. Double click on Export to excel button and write this code
if (dataGridView1.Rows.Count > 0)
{
Microsoft.Office.Interop.Excel.ApplicationClass XcelApp = new Microsoft.Office.Interop.Excel.ApplicationClass();
XcelApp.Application.Workbooks.Add(Type.Missing);
for (int i = 1; i < dataGridView1.Columns.Count + 1; i++)
{
XcelApp.Cells[1, i] = dataGridView1.Columns[i - 1].HeaderText;
}
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
for (int j = 0; j < dataGridView1.Columns.Count; j++)
{
XcelApp.Cells[i + 2, j + 1] = dataGridView1.Rows[i].Cells[j].Value.ToString();
}
}
XcelApp.Columns.AutoFit();
XcelApp.Visible = true;
Final Complete Code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace ExportDateFromGridViewToExcel
{
public partial class Form1 : Form
{
DataTable dt = new DataTable();
public static string FileName = "";
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
LoadGridData();
}
public void LoadGridData()
{
DataTable dt = new DataTable();
dt.Columns.Add("Name");
dt.Columns.Add("Address");
dt.Columns.Add("Mobile");
dt.Rows.Add("Ravi Kumar Soni", "Transport Department", "82690884xx");
dt.Rows.Add("Vikash Singh Chandel", "NIC", "82690482xx");
dataGridView1.DataSource = dt;
}
private void button1_Click(object sender, EventArgs e)
{
if (dataGridView1.Rows.Count > 0)
{
Microsoft.Office.Interop.Excel.ApplicationClass XcelApp = new Microsoft.Office.Interop.Excel.ApplicationClass();
XcelApp.Application.Workbooks.Add(Type.Missing);
for (int i = 1; i < dataGridView1.Columns.Count + 1; i++)
{
XcelApp.Cells[1, i] = dataGridView1.Columns[i - 1].HeaderText;
}
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
for (int j = 0; j < dataGridView1.Columns.Count; j++)
{
XcelApp.Cells[i + 2, j + 1] = dataGridView1.Rows[i].Cells[j].Value.ToString();
}
}
XcelApp.Columns.AutoFit();
XcelApp.Visible = true;
}
}
}
}
6. Run Code and click on Export to button.
