I have a MDI Parent Form that activates Child form where it contains a ListView. However, whatever settings I am doing and filling the items in the listView1 it doesn't display any whether in LargeIcon, SmallIcon, Detail or List. Doing it in MDI Parent form works but not in the Child Form. Is there anything I need to set before displaying listView? Note that both in the MDI Parent form and Child Form I am filling items programatically. But, defining ITEMS manually at design time (setting views, imagelists, etc) works. But I need to do FILL ITEMS at run time. Why it doesn't work in my Child Form?
