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

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

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

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
