listebox selecteditem at runtime in WPF

Listbox’s selected item property used to get/set values at runtime. In WPF you can used ViewModel to get selected item automatically to the ViewModel, that is for another article. Let’s learn how to set selected item at runtime,

• First we need to identify the element in List Item collection
• Set the property value

Getting the Item

var itt = (ListBoxItem)lstb_base.Items.Cast<ListBoxItem>().Where((s, b) => s.Content.Equals(r.M_Base)).SingleOrDefault();
                             

Set property of SelectedItem

lstb_base.SelectedItem = itt;
