如何相对于彼此以及表单本身来组织表单上的控件？
我在 MDI Windows 窗体应用程序中有一个子窗体。它有两个控件：一个 ComboBox 和一个 TreeView，最后一个控件位于第一个控件下面。两个控件具有相同的宽度。如何设置它们和表单属性以实现以下目的：
- 更改表单大小时，两个控件的宽度必须等于表单的宽度。
- TreeView 的高度必须更改以填充表单的所有可用空间。
I have a child form in a MDI Windows Forms application. It has two controls: a ComboBox and a TreeView, with the last one under the first one. Both controls have the same width. How can I set up them and form properties to achieve the following:
- When changing the size of the form, a width of both controls must be equal to the width of the form.
- The height of the TreeView must be changing to fill all free space of the form.

您可以这样做：
Anchor属性设置为 Top、Left 和 RightAnchor属性到顶部、左侧、右侧和底部You can do like this:
Anchorproperty to Top, Left and RightAnchorproperty to Top, Left, Right, and Bottom基本上，您需要对接控件。使用Dock 您的两个控件的属性，以找到适合您的要求的“对接”。
下面是一个示例，演示了带有
Dock=Top的 Combobox 和带有Dock=Fill的 TreeView：如果调整表单大小，组合框宽度和TreeView宽度/高度将相应调整大小，以满足您的具体要求。
Basically, you would need to dock your controls. Play with the Dock property of your both controls to find the "docking" which suits your requirements.
Here is an example which demonstrates a Combobox with
Dock=Topand TreeView withDock=Fill:If you resize the form, the Combobox width and TreeView width/height will be resized accordingly, which suits your specific requirements.
这是通过
Anchor属性完成的。在所有控件（组合框、树视图和用户控件）上正确设置它，它会按照您喜欢的方式拉伸。Dock属性类似，但它也会影响位置，甚至在表单设计器中也会将控件“粘合”到其位置。This is done by the
Anchorproperty. Set it properly on all controls (combobox, treeview and usercontrol) and it will stretch however way you like.The
Dockproperty is similar, but it also affects location and kinda "glues" the control to its place even in the form designer.
