Question

I have a MDIform application, where a form named MainForm is set to parent. Every time I open a new form I’m closing the others and I do it with custom method that gets 3 arguments one of which is object representing the MDIparent. Mostly I open forms from my MainForm which is also a MDIparent but I have this situation where I have to open a child form form another child form. Let’s say that if I call my method for opening a new form like :

NewForm newForm = getMyForm(this, arg2, arg3)

when I’m in the MainForm which is also a parent it’s easy. But how to call my method or how to pass the object which is my MDIparent when I’m calling from other child form?

Answer 1

You can use Form.MdiParent property which will give you the MDI Parent for the current form.

MainForm frm = this.MdiParent as MainForm;
if(frm != null)
    //form found
