There must be missing an easy way to double-click on a DataGridViewCell and be able to get it in edit mode so you can type into the cell and change the value.
here is my project code if you need the full source (Form1.cs, line 4533) and the DataGridView is on the "Settings" tab .
I have read some things but I would like to avoid as many event handlers as possible.

DataGridViewCell cell = dataGridViewSettings.Rows[e.RowIndex].Cells[e.ColumnIndex + 1];
cell.InitializeEditingControl(e.RowIndex, dataGridViewSettings.Rows[e.RowIndex].Cells[e.ColumnIndex + 1].Value, dataGridViewSettings.Rows[e.RowIndex].DefaultCellStyle);

//   dataGridViewSettings.Rows[e.RowIndex].Cells[e.ColumnIndex + 1].InitializeEditingControl(e.RowIndex, dataGridViewSettings.Rows[e.RowIndex].Cells[e.ColumnIndex + 1].Value, dataGridViewSettings.Rows[e.RowIndex].DefaultCellStyle);
//   dataGridViewSettings.EditMode = DataGridViewEditMode.EditOnEnter;

dataGridViewSettings.EditMode = DataGridViewEditMode.EditOnEnter;
dataGridViewSettings.ReadOnly = false;
