How to scale the size of textbox in Windows c# form

What I'm trying to do here is to have a textbox that'll grow in size as the tool is maximized. This is the default size:

This is when I increase the size of the form:

I have used 'Anchor' property for this. Under the 'Target Database' section, the server has Top Anchor property set. While for it's textbox, Top, Left, Right is used.

What exactly I want is for the textbox to grow in size to the right and also move to right.

Is it possible? Please suggest ways to do it. Thanks in advance.
