@Bradley: thanks for pointing me in the right direction

You will need to write a ControlDesigner class, then use it in a [Designer( ... )] attribute on your UserControl.

See the example here: http://msdn.microsoft.com/en-us/library/sycctd1z(v=VS.90).aspx

For the actual click:

http://msdn.microsoft.com/en-us/library/system.windows.forms.design.controldesigner.gethittest(v=VS.90).aspx

The ControlDesigner has a protected bool GetHitTest(Point point) method - you can implement this in your ControlDesigner and return true when you want your control to handle a click, based on the click‘s location on the screen.

禁止调整自定义控件的尺寸

有时我们在自定义控件时,出于某种原因的考虑(比如:防止在设计时误操作),想禁止调整自定义控件的尺寸(Height 或 Width).最初我是这样实现的,这也是较简单的方法: public class MyButton : System.Windows.Forms.Button { ... ... protected override voidOnResize(EventArgs e) { this.Height = 23; this.Width = 75; } } 但是我对这样的效果不太满意,要
