how can i make the mdi.Children raise a event on the mdi.Parent?!?!? to be more precise... i want to raise a event related with the dialogResult... cause u see my mdi children are edit dialogs... so... when the user press the "Confirm changes" i want to fire a event on the mdiParent... and if "cancel" is hit... do nothing... know what i mean?!?!

Your MDI child cannot be a dialog, the DialogResult property thus doesn't apply. Raising an event is otherwise not a problem. For example:

public partial class EditChildForm : Form {
public event EventHandler ApplyChanges;
public EditChildForm() {
InitializeComponent();
}
private void btnClose_Click(object sender, EventArgs e) {
if (ApplyChanges != null) ApplyChanges(this, EventArgs.Empty);
this.Close();
}
}

Usable from the MDI parent like this:

private void btnOpenEditor_Click(object sender, EventArgs e) {
EditChildForm frm = new EditChildForm();
frm.ApplyChanges += new EventHandler(frm_ApplyChanges);
frm.MdiParent = this;
frm.Show();
}

void frm_ApplyChanges(object sender, EventArgs e) {
EditChildForm frm = sender as EditChildForm;
// Do something...

}
