Question

I placed an MDI form in my application . If i select an option from file menu as New i will have a child form loaded.

My code is as follows to show the child form

  private void ShowNewForm(object sender, EventArgs e)
    {
        foreach (Form frm in Application.OpenForms)
        {
            if (frm.Text == "Main")
            {
                IsOpen = true;
                frm.Focus();
                break;
            }
        }
        if (IsOpen == false)
        {
            Form childForm = new FrmMain();
            childForm.MdiParent = this;
            childForm.Show();
        }
     }

Now what i need is when the child form is in active state i would like to have my MDI inactive until and unless the user closes the child form.

Generally for forms we will write

        frm.showDialog()

So how to resolve this

Answer 1

give like this

if (IsOpen == false)
        {

    Form childForm = new FrmMain();
         childForm.TopLevel=true;
         childForm.ShowInTaskbar=false;
         childForm.ShowDialog();
        }
