need advice - binding listview with poppup window in wpf c#.

Question

Hello everyone,

 

I have Listview with checkboxes.

 

 

After loaded listview, and check checkbox item then click on above button and want show a another window.xaml page like popup. 

 

 

 

 

 

 

After showing this poppup, then fill textbox again click on 'Save' button. Then I want to the remove listview checked items. How can I do this programmatically? I have tried...

 

Inside 1st class, I have get checked item's id and documentname (these are the stored procedure parameters) 

 private void Img_ArchiveSe_MouseLeftButtonDown1(object sender, MouseButtonEventArgs e)
        {
            foreach (DocumentsUser item in listView1.SelectedItems)
            {
                UserIdArc.Add(item.UserId.ToString());
                ImgNameArc.Add(item.Parent_File_Name);
            }
            AddArchiveNamexaml SP = new AddArchiveNamexaml();
            SP.ShowDialog();
}

public static ObservableCollection<string> ImgNameArc = new ObservableCollection<string>();
        public static ObservableCollection<string> UserIdArc = new ObservableCollection<string>();

 

 Then, 2nd class (ie; code behind of popup window.xaml) insted Save button click event, I have get list of items (List data = service.GetUserDocumentsArc(objUserIdArc, objImgNameArc); ) and want to bind listview from 1st class.

  private void btnAddUser_Click(object sender, RoutedEventArgs e)
        {
            DMSBusinessLayer service = new DMSBusinessLayer();
            string objImgNameArc = string.Join(",", UC_FileMgmt.ImgNameArc.ToArray());
            string objUserIdArc = string.Join(",", UC_FileMgmt.UserIdArc.ToArray());
            List data = service.GetUserDocumentsArc(objUserIdArc, objImgNameArc);
}

 I have done, is this correct or not ? Please advice me.
