Enabled/Desabled Main Item Menu when I click on mdi Child form

[vladam]

Plesa help me !

How can I enable/disable Menu Item (Menu is MainMenu for App.) on mdi
parent form when I click on some control in activ child form?

vladam,

There are a few ways you can do this. The first would be to pass a
reference for the main form to the child form, and then have the child
modify the enabled/disabled state of the menu item when needed. Of course,
this means that you have to publically expose the menu items on the main
form.

The second option you have is to have an event that the child form
fires, that the parent form hooks up to. When the event is fired,
enable/disable the menu item.

Hope this helps.

public System.Windows.Forms.MenuItem mnuItem1;
.....
.....
private void mnuItem1_Click(object sender, System.EventArgs e)
{
MenuExample.frmChild newForm = new
frmChild(this);
newForm.Show();
}



childForm
.....
public frmChild(MenuExample.frmMain parent)
{
//
// Required for Windows Form Designer support
//
InitializeComponent();

// Veza sa roditeljem
this.MdiParent=parent;
.....

private void btnItem1_Click(object sender, System.EventArgs e)
