C# datagridview doubleclick on row with FullRowSelect

cdatagridviewdouble-clickevents

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 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());
    }

I figured out a better way of doing this, using the CellFormatting event:

Private Sub uxContacts_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles uxContacts.CellFormatting
    If uxContacts.CurrentCell IsNot Nothing Then
        If e.RowIndex = uxContacts.CurrentCell.RowIndex And e.ColumnIndex = uxContacts.CurrentCell.ColumnIndex Then
            e.CellStyle.SelectionBackColor = Color.SteelBlue
        Else
            e.CellStyle.SelectionBackColor = uxContacts.DefaultCellStyle.SelectionBackColor
        End If
    End If
End Sub

C# – Getting data from selected datagridview row and which event

You can use SelectionChanged event since you are using FullRowSelect selection mode. Than inside the handler you can access SelectedRows property and get data from it. Example:

private void dataGridView_SelectionChanged(object sender, EventArgs e) 
{
    foreach (DataGridViewRow row in dataGridView.SelectedRows) 
    {
        string value1 = row.Cells[0].Value.ToString();
        string value2 = row.Cells[1].Value.ToString();
        //...
    }
}

You can also walk through the column collection instead of typing indexes...
