FormStartPosition.CenterParent does not work

Question

In the following code, only the second method works for me (.NET 4.0). FormStartPosition.CenterParent does not center the child form over its parent. Why?

Answer 1

I found setting the location manually is the only reliable option in some more complex cases when form is auto-sized and dynamically modified.

However rather than computing the coordinates manually, I'd suggest using existing method:

this.CenterToParent();
