如何在treeview中进行垂直和水平滚动？

Question

我有一个固定大小的树形视图。我怎样才能让它滚动到水平和垂直？当我将Scrollable设置为true时，它只添加垂直滚动条，当滚动条到达表单底部时，剩下的文本不会滚动。请帮助我。

P.S对不起英文不好

Answer 1

你可以试试这个方法

private const int WM_SCROLL = 276; // Horizontal scroll 
private const int WM_VSCROLL = 277; // Vertical scroll 
private const int SB_LINEUP = 0; // Scrolls one line up 
private const int SB_LINELEFT = 0;// Scrolls one cell left 
private const int SB_LINEDOWN = 1; // Scrolls one line down 
private const int SB_LINERIGHT = 1;// Scrolls one cell right 
private const int SB_PAGEUP = 2; // Scrolls one page up 
private const int SB_PAGELEFT = 2;// Scrolls one page left 
private const int SB_PAGEDOWN = 3; // Scrolls one page down 
private const int SB_PAGERIGTH = 3; // Scrolls one page right 
private const int SB_PAGETOP = 6; // Scrolls to the upper left 
private const int SB_LEFT = 6; // Scrolls to the left 
private const int SB_PAGEBOTTOM = 7; // Scrolls to the upper right 
private const int SB_RIGHT = 7; // Scrolls to the right 
private const int SB_ENDSCROLL = 8; // Ends scroll 

[DllImport("user32.dll",CharSet=CharSet.Auto)] 
private static extern int SendMessage(IntPtr hWnd, int wMsg,IntPtr wParam, IntPtr lParam); 

SendMessage(treeView.Handle, WM Scroll Message, (IntPtr) Scroll Command ,IntPtr.Zero); 

向上滚动一页

SendMessage(treeView.Handle, WM_VSCROLL,(IntPtr)SB_PAGEUP,IntPtr.Zero); 

滚动翻页

SendMessage(treeView.Handle, WM_VSCROLL,(IntPtr)SB_PAGEDOWN,IntPtr.Zero);

什么结束了实效F或者我正在修理[keyboardP]的代码片段：

myTreeView.Nodes[myTreeView.Nodes.Count - 1].EnsureVisible(); 

presto。单杠。
