For the first portion -

First off, I'd recommend using the Anchor property on UserControl instead of trying to size this yourself. It works very simply, and very reliably, for handling window resizing.

If you want to do this, you should probably look at chaining off this.ClientSize instead of this.Height and this.Width. You're probably setting your control too large, and that's unachoring the panel or other thing you're sitting on, which causes all sorts of issues.

The second part is due to the fact that gridNameValue Properties.Size.Width is a member of a struct.

When you call gridNameValueProperties.Size, you're returning a Size struct, then trying to set the Width on the returned struct (not the original). This is why you need to set the entire Size valuetype in one shot. Creating a new Size() and setting it to gridNameValueProperties.Size is the only way to make that work.
