面板自动滚动最大值 [英] Panel Autoscroll Maximum Value

问题描述

我创建窗体并添加具有自动滚动功能的面板为true；

I create Form and I add Panel with Autoscroll is true;

之后，我添加此代码；

After than , I Add this code;

Int32 _y =0;
progressBarX1.Maximum = 600;


for (int i = 0; i <= 600;i++ )
{
    progressBarX1.Value = i;
    ButtonX _btn = new ButtonX();
    _btn.Click += new EventHandler(_btn_Click);
    _btn.Width = 100;
    _btn.Visible = true;
    _btn.Height = 70;
    _btn.Text = i.ToString();
    _btn.Left = 0;
    _btn.Top = _y;
    _y += 80;
    panel1.Controls.Add(_btn);
}

我运行了该项目，但是在面板中我只看到407按钮，我无法使用vscroll向下移动.面板上未显示所有其余按钮.但是代码是在面板上添加按钮.我检查Tab和按钮是否在那里.我认为问题是面板滚动.最大高度是32500 aproxilamte.因此，Vscroll最多可以将此32500值降低.

I run the project, but in Panel I see just 407 button, I can not move down with vscroll. All rest buttons doesnt show in panel. But the code is add button to panel. And I check with Tab and buttons are there. The problem Panel Scrolling are I think. Max Height is 32500 aproxilamte. So Vscroll down max this 32500 value.

如何增加自动滚动高度"区域?

How Can I increase the Autoscroll Height area ?

推荐答案

自动滚动不是问题.

不幸的是，对于x或y，控件的最大位置是32767. 因此，面板在最高位置将所有按钮相互绘制.

Unfortunately the maximum location for a control is 32767 for either x or y. So the panel is drawing all the buttons on top of each other at the highest location.

如果在最后一个按钮上调用BringToFront，它将变为可见.

If you call BringToFront on the last button, it will become visible.
