Super slow C# custom control

Question

I\'ve made a custom control, it\'s a FlowLayoutPanel, into which I put a bunch of other custom controls (just Buttons, each with three Labels and a PictureBox overlayed)

Answer 1

At 1000+ buttons your probably running perilously low on GDI resources and/or raw handles for your application.

Not sure what your application is supposed to do but a grid or a combo box may be the better option here.
