Listbox items in WPF: strange behaviour

Question

Hi I need a little help with listboxes. I have created a listbox in WPF and added items with the listbox1.items.Add(...) method from the c# code. The items appear alright but I can't select them one-by-one selection is all messed up. Seems that these items have the same index. How can I get listbox.items.add to work correctly? Thank you in advance V

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.
