Question

I want to customize the following Listbox-display property of border with CornerRadius=5..can anyone help me to achieve it without changing the existing datatemplate code in

Answer 1

If you want the Border within the ListBoxItems to have another CornerRadius value, you can either re-template ListBoxItem where the Border is defined, or set it implicitly in the ItemContainerStyle Resources

Edit: If you want to set CornerRadius for the ListBox, you can do the same but in Resources instead
