Reply thank moderator, GotFocus Settings, if form the current focus in DataGridView, user Alt + TAB to switch to other program, switch will trigger GotFocus incident when I come back again, this will get rid of the user selected before line,
GotFocus other events can trigger in the user clicks the Datagridview

Record before the user choose the index of the line, again enters gotfocus judge whether the index is equal to zero, not equal to zero for selected=false Settings,
Or consider the tabindex directly set to 1, do not accept the TAB key events,

Enter GotFocus event, select rows in fact has been on the first line, automatic judgment choose line at that time is the first row, so can't distinguish user to select the first line of the automatically placed in the first row,
Tabstop set to False, the user can't use the keyboard operation,
