Question

User chose a folder containing files. I’m making a listview displaying the files in the chosen folder. I want to display what each file contains, but i want to display it when the user checks a file from listviewitem. I’m using the following code:

if (listView1.Items[0].Checked == true)
{
   //....
}

Why doesn’t it work? What should i want to use data from for example:

button1.Click(...) to button2.Click(...)?

Answer 1

Which event are you capturing? Remember if it’s the ItemCheck, that you cannot use the listView1.Item[0].Checked if that item was what was checked/unchecked. You need to take the ItemCheckEventArgs parameter, and using the e.Index, exclude that element when checking the entire listview elements. Use e.NewValue to separately evaluate the item that raised the ItemCheck event.
