You get the index number of the row in the datagridview using northwind database employees tables as an example:

using System;
using System.Windows.Forms;

namespace WindowsFormsApplication5
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            // TODO: This line of code loads data into the 'nORTHWNDDataSet.Employees' table. You can move, or remove it, as needed.
            this.employeesTableAdapter.Fill(this.nORTHWNDDataSet.Employees);

        }

        private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
        {
            var dataIndexNo = dataGridView1.Rows[e.RowIndex].Index.ToString();
            string cellValue = dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString();

            MessageBox.Show("The row index = " + dataIndexNo.ToString() + " and the row data in second column is: "
                + cellValue.ToString());
        }
    }
}

the result will show you index number of record and the contents of the second table column in datagridview:

Don t manually edit the  designer files in visual studio that usually leads to headaches  Instead either specify it in the properties section of your DataGridRow which should be contained within a DataGrid element  Or if you just want VS to do it for you find the double click event within the properties page- events  little lightning bolt icon  and double click the text area where you would enter a function name for that event    This link should help  http   msdn microsoft com en-us library 6w2tb12s v vs 90  aspx

In CellContentDoubleClick event fires only when double clicking on cell s content  I used this and works        private void dgvUserList CellDoubleClick object sender  DataGridViewCellEventArgs e                MessageBox Show e RowIndex ToString

This will work  make sure your control Event is assigned to this code  it has probably been lost  I also noticed that Double click will only work if the cell is not empty  Try double clicking on a cell with content  don t mess with the designer      private void dgvReport CellContentDoubleClick object sender  DataGridViewCellEventArgs e           do something

I think you are looking for this  RowHeaderMouseDoubleClick event  private void DgwModificar RowHeaderMouseDoubleClick object sender  DataGridViewCellMouseEventArgs e            to get the row index   int indice   e RowIndex

User · Answer

For your purpose  there is a default event when the row header is double-clicked  Check the following code    private void dgvCustom RowHeaderMouseDoubleClick object sender  DataGridViewCellMouseEventArgs e             Your code goes here

User · Answer

you can do this by   CellDoubleClick Event  this is code    private void datagridview1 CellDoubleClick object sender  DataGridViewCellEventArgs e                MessageBox Show e RowIndex ToString
