如何将form2的mdiParent设置为form1 c＃winforms

Question

I'm using two forms one mainform called 'Form1' and a seperate form called 'Form2'. So want to achieve something like that:

Form2.mdIparent = Form1;

But that didn't work. Can somebody help me ? I'm using Windows, C# and WinForms.

Answer 1

Make sure that Form2 has the property IsMdiContainer set to true.

Then, to define the caller Form being the parent of Form2 , use this (the current instance of Form1) instead of the name of the form class :

Form2.mdIparent = this;

Answer 2

Try this:

from Form1

protected void Button_Click(object sender, System.EventArgs e){  
   Form2 newMDIChild = new Form2();  

   newMDIChild.MdiParent = this; //where this means Form1

   newMDIChild.Show(); //if need to open Form2 
}
