An MDI child can always get a reference to its parent using its MdiParent property.

As long as the variable on the parent form is declared to be internal or public, you can then access it as follows:

Elegant_Shop frmMain = (Elegant_Shop)this.MdiParent; // get reference to parent
textBox1.Text = frmain.eboname.ToString();

What you were doing wrong before, is to create a new instance of the parent form rather than referencing the existing instance.

If you send the variable from MDI PArent to Child, then you should create a public property/variable in the Child form.
While create the instance for the child form, the assign the value into the public variable or property.

Hope this helps you.
