C＃的WinForms TreeView控件删除水平滚动条 [英] C# WinForms TreeView remove Horizontal Scrollbar

问题描述

我需要只垂直滚动条一个TreeView。

I need to have a TreeView with only vertical scrollbar.

我试过的这个，但它不工作，所产生的滚动条没有做任何事情。

I tried this but it doesnt work, the resulting scrollbar doesnt do anything at all.

我试过相反（与user32.dll中的功能滚动为true，禁用水平滚动条） - 它不工作，当我足够长的东西添加到TreeView滚动条再次表明...

I tried the opposite (scrollable to true and disable horizontal scrollbar with that user32.dll function) - it doesnt work, when i add long enough stuff to the TreeView the scrollbar shows again...

推荐答案

您可以尝试在TreeView控件打开在 TVS_NOHSCROLL 窗口样式。要做到这一点，你必须像这样一个自定义的树视图扩展标准TreeView控件：

You can try turning on the TVS_NOHSCROLL window style on the treeview control. To do so you have to extend the standard TreeView control with a custom TreeView like this one :

public class NoHScrollTree : TreeView {
protected override CreateParams CreateParams {
get {
    CreateParams cp = base.CreateParams;
    cp.Style |= 0x8000; // TVS_NOHSCROLL
    return cp;
}
} }
