SuspendLayout C# Forms

Question

I have written a Flowsheeting GUI, where the user can add, delete reposition UserControls on the screen at runtime and connect them with GDI+ Drawn Lines to represent connections. The only problem is that I can not figure out how to prevent the form redrawing each UserControl one at a time when the form is Zoomed in or out, is there any way to have reposition the usercontrols and resize them before they are redrawn to the screen. I have tried using the suspend and resume layout methods withut any success on the both the parent form and on each user control. In VBA and so on there was a function called ScrenUpdating=false which achieved what I wanted, but in C# I can not find an equivalent command.
