// Summary:
// In the single line visualized on dataGridView, check first if the first element of line
// is equal to 1 (the side on the right of dot in the name property),
// if it's not it asks to user if wants to add the first element. Then asks to the user
// if the last element is the correct one. And the finally adds all missing elements
// inside the line based on succesive numbers from first element to the last.
// Parameters:
// dataGridView that represents the current visualization on the application
// boolean variable that allows to switch the operation whether the line is in ascending order
// or in descending order
// Returns:
// None
