Checking Listbox selected

[chezealot9]

Hey Guys, for a listbox component, how can I check that the user has selected a row from it? I have a button and need to make sure a row is chosen before trying to process one.

Thanks for any help!!

If no item(s) is selected in a list box, the SelectedIndex property is -1. So this logic should work:

if(MyListBox.SelectedIndex > 0)
{
// process selected value(s)
}
else
{
// do something else
}
