UserControl - Paint in Design Mode

[Guest]

I have a usercontrol that requires I draw some lines on it which depend on
the size of the control. In the Design Mode I add the control to a form in
my application and change the size of the control. How do I show the new
lines which will be drawn while in the design mode. I tried overriding paint
but this doesn't show up until runtime.

Hi,

Try setting the resize redraw style in the control. Add
this to the new procedure of the control

me.setstyle(controlstyles.resizeredraw,true)

Then which event do I put my line drawing routines in? I tried adding the
line to the new sub of the control and drawing the lines in the paint event
but there were no lines in the control until I ran the application.
