How to reload a form after inserting new data

My problem has been solved myself, It just simply recalls the populate method.
Anyway thanks so much for caring my question. I wish you guys the best

can you give me more details :( sorry I'm newbie

Sorry because I really don't know what exactly the code in the Insert Button is, then I post this question, your answer didn't help

private void bttInsert_Click(object sender, EventArgs e)
{
string MSV, HoTen, MaLop;
MSV = textBoxMaSV.Text;
HoTen = textBoxHoTen.Text;
MaLop = comboBoxMaLop.Text;
new DBConnect().Insert(MSV, HoTen, MaLop);
//Code to bind the listview
}

here is the code in the InsertButton click event
private void bttInsert_Click(object sender, EventArgs e)
        {
            string MSV, HoTen, MaLop;
            MSV = textBoxMaSV.Text;
            HoTen = textBoxHoTen.Text;
            MaLop = comboBoxMaLop.Text;
            new DBConnect().Insert(MSV, HoTen, MaLop);
            //Application.Restart();
           
        }

just separate the bindmethod and call it after insert.

if any doubt share your code
