How to make Usercontrol fill all Tabpage

Question

I am placing a Usercontrol inside a Tabpage. When not Maximized, the Usercontrol fills all Tabcontrol

However, if I maximize the screen, there is a space on the right.

I used usercontrol winforms "Anchor" or "Dock" property. So I tried the following

control.Dock = DockStyle.Fill
control.Dock = AutoScaleMode.None

I’ve tried too, but he only centralizes Usercontrol.

control.Anchor = AnchorStyles.None
control.Left = (tab.Width - control.Width) / 2
control.Top = (tab.Height - control.Height) / 2

Answer 1

If you edit some property like Control.Top or Control.Anchor the property Dock will be discarded. Only edit property Dock control, nothing more.

control.Dock = DockStyle.Fill

If you touch the property Anchor after the Dock, the glue will be discarded.
