C# DataGridView how to programatically fire the selected event

I have a DataGridView in a form and I have the following code:

 //Scroll to the last row
            gridStore.FirstDisplayedScrollingRowIndex = gridStore.RowCount - 1;
            // select new row
            gridStore.Rows[gridStore.Rows.Count - 1].Selected = true;

I realize that .Selected doenst fire the SelectionChange event:

 private void gridStore_SelectionChanged(object sender, EventArgs e)
        {

        }

And I need to fire that event when the row is selected programatically.

Any clue?

As you rightly figured out, when the SelectMode set to FullRowSelect SelectionChanged event will not fire.

You have two workarounds to fix this issue.

Option 1

Separate the logic you would like to perform in common between gridStore_SelectionChanged and when you update the selection explicitly and call that method in both events.

private void DoSomething()
{

}

private void gridStore_SelectionChanged(object sender, EventArgs e)
{
     ...
     DoSomething();
}

and

gridStore.FirstDisplayedScrollingRowIndex = gridStore.RowCount - 1;
// select new row
gridStore.Rows[gridStore.Rows.Count - 1].Selected = true;

DoSomething();

Option 2:

Explicitly you trigger the event after making the selection (not preferable way, but works).

gridStore.FirstDisplayedScrollingRowIndex = gridStore.RowCount - 1;
// select new row
gridStore.Rows[gridStore.Rows.Count - 1].Selected = true;
gridStore_SelectionChanged(this, new EventArgs())
