Show a child form in the centre of Parent form in C#

Asked 2009-06-03T13:54:49.507

I create a new form and call from the parent form as follows:

loginForm = new SubLogin();   
loginForm.Show();

I need to display the child form at the centre of the parent. So,in the child form load I do the foll:`

Point p = new Point(this.ParentForm.Width / 2 - this.Width / 2, this.ParentForm.Height / 2 - this.Height / 2);
this.Location = p;

But this is throwing error as parent form is null. I tried setting the Parent property as well, but didn't help. Any inputs on this?

The parent probably isn't yet set when you are trying to access it.

Try this:

loginForm = new SubLogin();
loginForm.Show(this);
loginForm.CenterToParent()

Why not use this?

LoginForm.WindowStartupLocation = Windows.WindowStartupLocation.CenterOwner
