我必须为流布局面板项目创建向上和向下按钮垂直滚动。我该怎么办？我会为POS做这个表格。 我这样做，但它不工作：我有很多按钮，他们有87尺寸高度：我添加了代码和图片。 private void btnScrollUp_Click(object sender, EventArgs e) { flowLayoutPanel1.VerticalScroll.Value = flowLayoutPanel1.VerticalScroll.LargeChange-1 ; flowLayoutPanel1.PerformLayout(); } private void btnScrollDown_Click(object sender, EventArgs e) { flowLayoutPanel1.VerticalScroll.Value = flowLayoutPanel1.VerticalScroll.LargeChange+ 1; flowLayoutPanel1.PerformLayout(); }

什么类型的滚动的，你想实现的，将这段代码是吗？ How to Programmatically Scroll a Panel 这可以让你每个控制滚动，而不是一个“平稳”的滚动，但我认为这会为你的应用程序。

或者你可能只是想设置“自动滚动”假下面的代码实现适当的编程滚动： public Form1() { InitializeComponent(); flowLayoutPanel1.AutoScroll = false; } public int scrollValue = 0; public int ScrollValue { get { return scrollValue; } set { scrollValue = value; if (scrollValue < flowLayoutPanel1.VerticalScroll.Minimum) { scrollValue = flowLayoutPanel1.VerticalScroll.Minimum; } if (scrollValue > flowLayoutPanel1.VerticalScroll.Maximum) { scrollValue = flowLayoutPanel1.VerticalScroll.Maximum; } flowLayoutPanel1.VerticalScroll.Value = scrollValue; flowLayoutPanel1.PerformLayout(); } } private void Add_Control(object sender, EventArgs e) { flowLayoutPanel1.Controls.Add(new Button(){Width = flowLayoutPanel1.Width, Height = 87}); } private void UpClick(object sender, EventArgs e) { ScrollValue -= flowLayoutPanel1.VerticalScroll.LargeChange; } private void DownClick(object sender, EventArgs e) { ScrollValue += flowLayoutPanel1.VerticalScroll.LargeChange; }
