Here is what I did wrong I started a new C# project and created a form
then I opened a VB.Net project and copied a DataGridView (DGV) that was on a
form and pasted it into my C# form.
Populated the DGV from the SQLite DB great it worked.
Proceeded to write code to capture the values in the DGV cells.
After more hours I care to admit to NOTHING was working.
Looking in the VS 2019 ToolBox I noticed two DGV one under All Windows Forms
and one under Data.
For anyone reading this POST I am guessing that you need to use the DGV
under All Windows Forms for VB.Net and for C# you need the DGV under Data.

So I am really asking is my guess CORRECT ?
How in the name of St. Novice do you know to use the one under Data?

What I have tried:

This is just the code I used to capture the values in the DGV by click on the cell. It is here because I am proud of it and it nice to contribute St.Novice

private void dgvPerson_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    int ID = 0;// Declare this top level
    ID = Convert.ToInt32(dgvPerson.Rows[e.RowIndex].Cells[0].Value.ToString());
    tbID.Text = ID.ToString();
    tbFName.Text = dgvPerson.Rows[e.RowIndex].Cells[1].Value.ToString();
    tbLName.Text = dgvPerson.Rows[e.RowIndex].Cells[2].Value.ToString();
}
