    Hello Telerik Team.

    I've been having an issue with the example shown in

    I basically use pretty much the same example with a few changes, but when I want to modify anything from the list binded to the PageViewModel.Pages property, it simply doesn't work.  I've debugged my app, and the list is modified correctly, but the changes are not rendered in screen.

    I've tried so many things, but it simply doesn't work or raises an unhandled exception that says "the value does not fall within the expected range"

    If I try this... changes the list, but it's not rendered...

    this.listaPaginas.Where(c => == idPagina).First().nombre = tbNombre.Text;
    this.nPaginas.Pages = (IEnumerable<modeloPagina>)this.listaPaginas;

    Where "this.nPaginas" is the dataContext of Pager in your example.

    And, if I try this... it throws the unhandled error shown in the attached file.

    modeloNPaginas nuevoPages = new modeloNPaginas();
                    this.listaPaginas.Remove(this.listaPaginas.Where(c => == idPagina).First());
                    nuevoPages.Pages = (IEnumerable<modeloPagina>)this.listaPaginas;
                    this.nPaginas = nuevoPages;
                    this.Pager.DataContext = null;
                    this.Pager.DataContext = this.nPaginas;

    Could you guys please help me?

    Hi Miroslav,

    Ok.. the ticket will be opened asap, it's just that i can't do it because i didn't buy the bundle, so i'm trying to contact the people who bought it and send to you the project reproducing the error.

    I'll post asap the ticket number.
