Enabling / Disabling ToolStripMenuItem when clicked

I've two forms (called form1 as mdi container and form2) with an opentoolstripmenuitem in form1, when opentoolstripmenuitem clicked form2 called and opentoolstripmenuitem become disable, but when i click closebox in the top right of form2 the opentoolstripmenu still disable, i want it to enable again when closebox clicked.

Here my code in form1 :

private void openToolStripMenuItem_Click(object sender, EventArgs e)
{
    openToolStripMenuItem.Enabled = false;
    Form2 newMDIChild = new Form2();
    newMDIChild.MdiParent = this;
    newMDIChild.Show();            
}

any advice??

Solution

  • In the click handler, create a handler for the Closing or Closed event for Form2:

    newMDIChild.FormClosed += new FormClosedEventHandler(newMDIChild_FormClosed);

    and

    void newMDIChild_FormClosed(object sender, FormClosedEventArgs e)
{
        openToolStripMenuItem.Enabled = true;
}
