Hi,
I'm developing a WPF app, in which i have a main wpf form with List View and a button to open a Popup which intern having two text fields with Add button. Once I click the Add button, thew two txts will be added to a xml file on my local system and the popup will be closed after that. Now my requirement is that once the popup is closed, its parent main form ListView should be updated with the txt names which have been written to xml file.

Whenever I'm clicking the Add button the txt names have been added to the xml file and popup is closed automatically. But when the control goes back to the main form, the listView is not updates automatically. Please anyone help me on this.

Thanks in advance.

HI, try using ObservableCollection instead of list. normaly the view should update automatically once youuse this type instead of old list.

Solution 1

Use ObservableCollection instead of generic list and implement INotifyPropertyChange.

Solution 2

i think you could also manually refresh your items with: listView.Items.Refresh()
