C＃的WinForms：让面板滚动条看不见的 [英] C# WinForms: Make panel scrollbar invisible

问题描述

我有一个 PANEL1 与自动滚屏= TRUE 。我必须让 PANEL1 与 btnUp 和 btnDown 滚动。到目前为止，我做了什么，我问

I have a panel1 with AutoScroll = true.I have to make panel1 scroll with btnUp and btnDown. So far I've made what I was asked for

private void btnUpClicked(Object sender, EventArgs e)
{
    if (panel1.VerticalScroll.Value - 55 > 0)
        panel1.VerticalScroll.Value -= 55;
    else  panel1.VerticalScroll.Value = 0;
}

private void btnDownClicked(Object sender, EventArgs e)
{
    panel1.VerticalScroll.Value += 55;
}

但现在我需要隐藏滚动条或使其不可见。我试过

But now I need to hide Scrollbar or make it invisible. I tried

panel1.VerticalScroll.Visible = false;

，但它不工作。任何想法家伙？

but it doesn't work. Any ideas guys?

推荐答案

好吧，我已经做了这对你的工作示例。所有你所要做的就是改变这取决于您的面板中的所有项目的总大小的最大值。

Ok, I've done the working example of this for you. All you have to do is to change the max value depending on the total size of all the items inside your panel.

表单代码：

public partial class Form1 : Form
{
    private int location = 0;

    public Form1()
    {
        InitializeComponent();

        // Set position on top of your panel
        pnlPanel.AutoScrollPosition = new Point(0, 0);

        // Set maximum position of your panel beyond the point your panel items reach.
        // You'll have to change this size depending on the total size of items for your case.
        pnlPanel.VerticalScroll.Maximum = 280;
    }

    private void btnUp_Click(object sender, EventArgs e)
    {
        if (location - 20 > 0)
        {
            location -= 20;
            pnlPanel.VerticalScroll.Value = location;
        }
        else
        {
            // If scroll position is below 0 set the position to 0 (MIN)
            location = 0;
            pnlPanel.AutoScrollPosition = new Point(0, location);
        }
    }

    private void btnDown_Click(object sender, EventArgs e)
    {
        if (location + 20 < pnlPanel.VerticalScroll.Maximum)
        {
            location += 20;
            pnlPanel.VerticalScroll.Value = location;
        }
        else
        {
            // If scroll position is above 280 set the position to 280 (MAX)
            location = pnlPanel.VerticalScroll.Maximum;
            pnlPanel.AutoScrollPosition = new Point(0, location);
        }
    }
}

图片例如：

您必须自动滚屏选项的面板上设置为假。我希望你明白我做了什么，并会得到你的面板上运行你想要的方式。随意问你是否有任何问题。

You have to set AutoScroll option to False on your panel. I hope you understand what I've done and will get your panel running the way you want. Feel free to ask if you have any questions.
