- by Aviatrix
my listview will display only the item that its added by the constructor and it wont add the items that i add dynamically
public class PostList : ObservableCollection<PostData>
{
public PostList()
: base()
{
Add(new PostData("Isak", "Dinesen"));
// Add(new PostData("Victor", "Hugo"));
// Add(new PostData("Jules", "Verne"));
}
public void AddToList (string[] data){
string username2, msg;
msg = data[0];
username2 = data[1];
Add(new PostData(msg, username2));
}
}
public class PostData
{
private string Username;
private string Msg;
private string Avatar;
private string LinkAttached;
private string PicAttached;
private string VideoAttached;
public PostData(string msg ,string username, string avatar=null, string link=null,string pic=null ,string video=null)
{
this.Username = username;
this.Msg = msg;
this.Avatar = avatar;
this.LinkAttached = link;
this.PicAttached = pic;
this.VideoAttached = video;
}
public string pMsg
{
get { return Msg; }
set { Msg = value; }
}
public string pUsername
