How to replace a Inline object to another Inline inside a Paragraph (Windows.Document)?
I'm menaging a Paragraph to replace a line (Inline) of a RichTextBox.
But Paragraph.Inlines that is a InlineCollection don't have a index selector like
Paragraph.Inlines[0] and I need to replace a item inside this collection. How can I do that? Resuming: How can I replace a item inside a collection that does not have the index selector.
I tried this, but he throws this "'InlineCollection' element cannot be inserted in a tree because it is already a child of a tree.":
public List<ControlMessages> ControlMessages = new List<ControlMessages>();
public Paragraph PTrace = new Paragraph();
public void WriteControlMessage(string _id, string _message) {
ControlMessage cm = new ControlMessage(_id, _message);
ControlMessages.Add(cm);
PTrace.Inlines.Add(cm.Line);
}
public void UpdateControlMessage(string _id, string _message) {
ControlMessage cm = ControlMessages.Where(wh => wh.Id == _id).FirstOrDefault();
cm.SetMessage(_message);
PTrace.Inlines.InsertAfter(cm.OldLine, cm.Line);
PTrace.Inlines.Remove(cm.OldLine);
}
public class ControlMessage {
public string Id { get; set; }
public Inline Line { get; set; }
public Inline OldLine { get; set; }
public ControlMessage(string _id, string _message) {
Id = _id;
SetMessage(_message);
}
public void SetMessage(string _message) {
OldLine = Line;
Paragraph p = new Paragraph();
p.Inlines.Add(_message);
Line = p.Inlines.LastInline;
}
}
