c# datagridview doubleclick on row with FullRowSelect

I have a datagridview in my C# application and the user should only be able to click on full rows. So I set the SelectionMode to FullRowSelect.

But now I want to have an Event which is fired when the user double clicks on a row. I want to have the row number in a MessageBox.

I tried the following:

 this.roomDataGridView.CellContentDoubleClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.roomDataGridView_CellCont‌ ​entDoubleClick); 

 private void roomDataGridView_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
 {
      MessageBox.Show(e.RowIndex.ToString());
 }

Unforunately nothing happens. What am I doing wrong?

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

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
 }

you can do this by : CellDoubleClick Event this is code. 

private void datagridview1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
    {
        MessageBox.Show(e.RowIndex.ToString());
    }

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:

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());
    }

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 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


 }
