As you know by question that what I want. I was using listbox. In ListBox we can get selected item by a simple line of code:
listbox1.SelectedItem.
ListView returns collections of selected items and indices through the SelectedItems and SelectedIndices properties. Note that these collections are empty, if no item is currently selected (lst.SelectedItems.Count = 0). The first item that is selected is lst.SelectedItems(0). The index of this item in the Items collection is lst.SelectedIndices(0). So basically
lst.SelectedItems(0)
is the same as
lst.Items(lst.SelectedIndices(0))
You can also use check boxes. Set CheckBoxes to True for this. Through the CheckedItems and CheckedIndices properties you can see which items are checked.
