Form’s AutoSize: False.
Form’s AutoSizeMode: Grow and Shrink.
Issue: I cant resize my form by dragging its borders, I can only do that by dragging that grip thing on the bottom right side of the form.
Is there any other property on the form that I sohlud change to fix this problem?
Here is also a screen shot of the hierarchy of controls on the form…maybe setting on lower level controls on the form is causing this?

Make sure the FormBorderStyle is set to Sizable, and that the SizeGripStyle property is set to Auto or Hide.
