list box no selection

[Guest]

if(listBox.SelectedItem.Text != null)
{
// test
}

This code gives exception if no item is selected in the list box, how can I
check if any item is selected or not?

try testing SelectedItem for null instead, before using the property.

if(listBox.SelectedIndex == -1)
{
// no items selected
