winforms - c# tabcontrol - tabpage -

i trying add tab page programmatically tabcontrol.

i can no problem, seems when add it, automatically sized 200px in width, , cannot work out how resize it. tabpage created in dll, , returned main client whereby added tabcontrol, when added 200px wide, , further controls add onto tabpage not show if positioned more 200px wide.

any ideas?

thanks.

either change size property

mytabcontrol.size = new system.drawing.size(400, 400); 

or height / width properties

mytabcontrol.height = 400; mytabcontrol.width = 400; 

or dock property

// size tab control take available space in parent container mytabcontrol.dock = dockstyle.fill;
