Listbox items in WPF: strange behaviour

Viktor P17y ago

I think I've found the problem. It was not that I used the same string over again - but that I added strings instead of objects called "listboxitems" with the appropriate "content" properties.
Thanks, anyways!

hi there ..

i is happening as you are trying to add the same object again and again.

just try to add different one to the list box like

decalre one variable i and increment in each click. then add the variable along with the name and check

i++;

listBox1.Items.Add("Amit"+i);

Thanks. It's set to single, but still the same.
I've also found that all the items added from c# have the same index property.

Make sure the SelectionMode is set to One.

private void button1_Click(object sender, RoutedEventArgs e)
        {
            listBox1.Items.Add("item")
        }
I press the button several times, and then try to select the items.

Can you post your code please?
