How to get scrollbar in Panel in VB.Net?
提问by Brijesh Patel
I am developing a Windows Application in VB.Net. In that, there is one case where there is one form, and in that form there is a Panel, and within the Panel there is a rich text box.
我正在 VB.Net 中开发 Windows 应用程序。在这种情况下，有一种情况，只有一个表单，并且在该表单中有一个面板，并且面板内有一个富文本框。
So my requirement is to get a scrollbar in the Panel. So when the user does scroll on the panel, the rich text box can scroll accordingly like MS Office functionality..
所以我的要求是在面板中获得一个滚动条。因此，当用户在面板上滚动时，富文本框可以像 MS Office 功能一样相应地滚动。
Can any one give me an idea how to do it?

Set the .Dock property to FILL and the .WordWrap property to FALSE for the richtextbox.
对于富文本框，将 .Dock 属性设置为 FILL，将 .WordWrap 属性设置为 FALSE。
Also set the Panel's .Dock property to FILL.
还将面板的 .Dock 属性设置为 FILL。

Set Panel.AutoScroll = Trueand scrollbars will automatically appear whenever any controls in the panel fall outside its boundaries.
Panel.AutoScroll = True只要面板中的任何控件超出其边界，设置和滚动条就会自动出现。

In order to use panel autoscroll property I do that:
为了使用面板自动滚动属性，我这样做：
panel.AutoScroll = true
panel.VerticalScroll.Visible = False or panel.HorizontalScroll.Visible = False
In order to know the dimensions of the scroolbars use
为了知道滚动条的尺寸使用
SystemInformation.HorizontalScrollBarHeight
SystemInformation.VerticalScrollBarWidth
So you can change the dimension of the panel when the scroolbar is shown.
因此，您可以在显示滚动条时更改面板的尺寸。
