Flowlayout面板禁用鼠标中轮滚动

Question

我想阻止Middle Mouse Wheel滚动FlowlayoutPanel

我尝试了但没有（为什么不知道）

flowLayoutPanel.MouseWheel += (sender, args) => 
    ((HandledMouseEventArgs)args).Handled = true;

Answer 1

我认为你必须自己继承控制并注释掉基本调用：

public class FlowPanel : FlowLayoutPanel {
  protected override void OnMouseWheel(MouseEventArgs e) {
    // base.OnMouseWheel(e);
  }
}
