DataGridView: Cell Value to Generic List

[Poab9200]

Hello all, I'll do my best to make this as simple as possible to explain.

1. I'm using a WinForm DataGridView.
2. I'm using an auto complete feature that I've coded and I'm trying to add the data that a user has entered in the first column to a generic list.

Here is some of my code:
dataGridView_EditingControlShowing

if (dgvCommands)
            {
                DataGridViewTextBoxEditingControl te = (DataGridViewTextBoxEditingControl)e.Control;
                te.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
                te.AutoCompleteSource = AutoCompleteSource.CustomSource;

                switch (dgv_Alias.CurrentCell.ColumnIndex)
                {
                    case 0:
                        te.AutoCompleteCustomSource.Clear();
                        break;
                    case 1:
                        te.AutoCompleteCustomSource.Clear();
                        te.AutoCompleteCustomSource.AddRange(sCommands);
                        break;
                }
            }
            else
            { }

This is the code that loads the commands to the sCommands Array List.

private List<string> Commands = new List<string>();
private string[] sCommands;
private bool dgvCommands;

private void AC_LoadCommands()
        {
            if (File.Exists(@"data/cmds.txt"))
            {
                StreamReader sr = new StreamReader(@"data/cmds.txt");
                string line;

                while ((line = sr.ReadLine()) != null)
                {
                    if (!line.Contains("//"))
                    {
                        Commands.Add(line);
                    }
                    else
                    { }
                }

                sr.Close();

                for (int i = 0; i != Commands.Count; i++)
                {
                    sCommands = Commands.ToArray();
                }

                dgvCommands = true;
            }
            else
            {
                MessageBox.Show("Missing File: 'data/cmds.txt'\nAuto Complete cannot function without this file.", "Missing File: 'data/cmds.txt'", MessageBoxButtons.OK, MessageBoxIcon.Error);
                dgvCommands = false;
            }

And that Method is loaded when the program starts under the Form_Loading Event.

Now I would like to gather the data from the first column and add it to the sCommands string array.

I need to know what events to use and a detailed example of how to go about doing so.

Any help would be greatly appreciated.

Thanks
