are adding column in constructor?

i've had problem in past items added in constructor added twice, because (i think) constructor gets called make control appear in designer view, (which gets added instance) , again when run program.

if what's happening you, need check aren't in design mode.

there few different ways check this, depending on context - see how tell if .net code being run visual studio designer
