Bind TextBox to Selected Item of ListBox

[OldNewbie]

Hello All

I have a textbox control. I would like this text box to automatically
update to contain the currently selected item located in a listbox
which is on the same form.

Do I need a CurrencyManager for this? Can this be done just by
manipulating the databindings properties of the textbox? If so, please
do give me some hints as to the syntax I would use to fill in that
field on the property panel - everything I try is rejected.

Disclaimer: No this is NOT my homework. I'm 45 years old, new to
CSharp and quite capable of digging most things up on the net for
myself. I just cannot seem to make this work. A few code snippets
would be much appreciated. Obviously I could code a manual procedure
for this - but hey CSharp is supposed to automate this sort of thing
(I think) and I wanna know how its done. I have seen all of the
dataset binding examples - nothing seems to work on the listbox to
textbox pair.

Cheers

From one old git to another

You could use the SelectedIndexChanged event on the listbox to update the
textbox:-
private void listBox1_SelectedIndexChanged(object sender, System.EventArgs
e)

{

this.textBox1.Text = this.listBox1.SelectedItem.ToString();

}

Ahh.... of course. So simple! Thank you.

Eventually I'm going to have to get to grips with the data binding and
CurrencyManager stuff but that can be put off to another day.

Cheers muchly
