FlowLayout 控制事件

Question

FlowLayout 中有很多按钮。当我单击按钮时，我希望正常颜色发生变化。当我第一次单击时，按钮的颜色会发生变化。这里没有问题，但是当我第二次点击另一个按钮时，我之前点击的按钮没有恢复。我能怎么做 ？

 int j =1;

    foreach (...)

                 {

                     BunifuFlatButton newButton = new BunifuFlatButton();

                     {

                         newButton.Name = string.Format("Button{0}", j);

                         flowLayoutPanel1.Controls.Add(newButton);

                         newButton.Click += NewButtonOnClick;

                         j++;

                     }

                 }

  private void NewButtonOnClick(object sender, EventArgs eventArgs)

        {

            BunifuFlatButton btn = (BunifuFlatButton)sender;

            btn.Normalcolor = Color.FromArgb(37, 66, 80);

        }
