Disable default cell selection in a datagridview after form load in WinForm Application

I have a dataGridView control in Window Form Application. Three columns are added to the dataGridView. I added 20 empty rows into dataGridView in order to show some blank cells.(Otherwise dataGridView just shows grey area).

On dataGridView control, I add three column "a","b", "c". In form load, I add this,

dataGridView1.Rows.Add(20);

after form initialize, datagridview shows some blank cell, but first cell in first row is selected(highlighted with blue color). Please note, there is no data in datagridview. I could not figure out how to clear the default selection.

I did some research. There are some discussion. I tried, ,and they were not working. I think it is because I don't have data in the control. But the method mentioned in the following link, is for a datagridview loaded with data.

Also there are some discussion regarding Windows store application. (I am using windows form application)

If anyone is still having troubles with this I have found this worked for me when all the above suggestions failed.

On the DataGridView create an event for DataBindingComplete then add this method datagridview1.ClearSelection();

In my case, i got it working using this piece of code:

dataGridView1.EndEdit();

Hope this helps someone.

I can't reproduce in a fresh test DGV but I have seen it before.

Here is what I found to work:

bool old = dataGridView1.MultiSelect;
dataGridView1.MultiSelect = false;
dataGridView1.Rows[1].Cells[0].Selected = true;
dataGridView1.Rows[1].Cells[0].Selected = false;
dataGridView1.MultiSelect = old;

I don't know what causes this sometimes.. (..but I will add it to the answer once I do.)
