c# datagridview doubleclick on row with FullRowSelect

Question

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?

In the designer I write this.roomDataGridView.CellContentDoubleClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.roomDataGridView_CellContentDoubleClick); — Metalhead89, Dec 04 '12 at 15:25
I just deleted my event and did it again and now it works. I really dont know what was going on but it works now — Metalhead89, Dec 04 '12 at 15:28
@Metalhead89: There was a space in `(this.roomDataGridView_CellContentDoubleClick);` — gaynorvader, Dec 04 '12 at 15:30

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());
    }

Be sure to either handle the CellContentsDoubleClick or CellDoubleClick, not both, as they will cancel each other out (assuming you are doing the same thing). Basically they both get fired. – Rob Mar 13 '18 at 13:40

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.

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:

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

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

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

Your answer is incomplete, you don't explain how to add an event listener, etc... – Cid May 31 '18 at 12:23

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
 }
