Use
dataGridView2.CurrentCell = dataGridView2[2, 1];
I got the multiple cell selection to work by using:
dataGridView2.MultiSelect = true;
dataGridView2.SelectionMode = DataGridViewSelectionMode.CellSelect;
dataGridView2.CurrentCell = cableGrid[2, 1];
dataGridView2[2, 1].Selected = true;
dataGridView2[3, 1].Selected = true;
I found that without first setting
CurrentCell
then
Selected = true
did not work.
After adding this line though I was able to select as many cells as I wanted.
Not entirely sure why it works this way, I am curious if anyone knows the answer though.
