childForm.MdiParent = this;<br />
so the <b>this.MdiParent</b> in your child should give you what you want

C#2010 winforms referencing the mdi parent form from a class

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
