The exception is thrown only when I use the show() method, here's the code:
public partial class DetailOS : ContentPage
{
SfPopupLayout Popup { get; set; }
public string MotivoCancel { get; set; }
Models.Manutencao.Pedido Pedido { get; set; }
public DetailOS (Models.Manutencao.Pedido obj)
{
InitializeComponent ();
Pedido = obj;
Popup = new SfPopupLayout();
Popup.PopupView.AppearanceMode = AppearanceMode.TwoButton;
Popup.PopupView.HeaderTitle = "Cancelar OS";
Popup.PopupView.PopupStyle = new PopupStyle {
AcceptButtonBackgroundColor = Color.FromHex("#009530"),
AcceptButtonTextColor = Color.White,
DeclineButtonBackgroundColor = Color.FromHex("#009530"),
DeclineButtonTextColor = Color.White
};
Popup.PopupView.ContentTemplate = new DataTemplate(() => {
var txt = new Entry { Placeholder = "Informe o motivo" };
txt.BindingContext = this;
txt.SetBinding(Entry.TextProperty, "MotivoCancel");
return txt;
});
Popup.PopupView.DeclineButtonText = "VOLTAR";
Popup.PopupView.AcceptButtonText = "CANCELAR";
Popup.PopupView.AcceptCommand = new Command(Cancelar);
BindingContext = new ViewModels.Manutencao.DetailOS () { Pedido = obj, Navigation = Navigation };
}
async void CancelarPopUp(object sender, EventArgs e)
{
try {
if (Pedido.Status == "aberto") {
Popup.Show();
} else {
await DisplayAlert("Acesso Restrito", "Essa OS não pode ser cancelada em seu atual estágio do processo", "OK");
}
} catch (Exception ex) {
await DisplayAlert("Exceção : Contate o administrador", ex.Message, "dismiss");
}
}
}
Didn't include the whole class here, just the methods that have some interaction with the Popup.
I made sure to include the xmlns:syncfusion="clr-namespace:Syncfusion.XForms.PopupLayout;assembly=Syncfusion.SfPopupLayout.XForms" in the xaml.
The stack trace is the following:
