c# winforms - how to access ParentForm from ChildForm

Question

I readed manu articles about this but - still confused. from Form1 I open Form2: new Form2().Show(); On Form2.ClosingEvent I need: Form1.TextBox1.Visible = false; What code and exactly where should I put - to achieve this ?

In form1 set TextBox1 Modifiers property to internal if form1 and form2 are in same assembly else set it Public Also you should not create form1 reference using new keyword You can pass form1 reference to a parameterized constructor of form2 and then use the same See similar post http://www.c-sharpcorner.com/Forums/Thread/172402/calling-button-object-from-another-winform.aspx

Finally I succeed. Ugh! - and - Thanks! I remember in some other langugages it's so simple: Form1.TextBox1.Visible = False. Why is c# so complicated without any reason ? And in the same time - so pupular ?
