Redirect or capture keydown event from a child form

[Frank T. Clark]

How do I redirect or capture keydown events in a parent form from a child
form?

I have a main form which displays another informational form marked
"SizableToolWin dow".

Form child = new ChildForm();

this.AddOwnedFo rm (child);

child.Show();

I don't want the child form to be active just to show information. I do want
the user to be able to move the form and change the size. How do I make sure
that the information from any keydown events goes to the parent form?

I have programmed extensively in C using the Win32 API but I am only
starting with C#.

You could create an event in the child. The parent
subscribes to it.
Whenever the keydown is fired on the child, you should
fire your event. Since the main form will be subcribing to
it, it will also get the events.

Re: Redirect or capture keydown event from a child form

Try adding a KeyEventHandler when you create the child form:

//Create child
private void mnuFileNew_Clic k(object sender, System.EventArg s e)
{
frmChild child = new frmChild();
frmChild.MdiPar ent = this;
frmChild.Show() ;
//Raise keydown events to this form
frmChild.KeyDow n +=new KeyEventHandler (frmChild_KeyDo wn);
}
//Child form KeyDown event raised to parent
private void frmChild_KeyDow n(object sender, KeyEventArgs e)
{
//process key here
}
