I am currently trying to build two separate collection views on the same page in Xamarin. I keep getting the error that content is set more than once and also that I've set the content binding more than once. How do I add different bindings to two separate collection views on the same page?
ConsumerOrders.xaml page:

AddedServicesViewModel.cs :
using Shared.Models;
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Text;
namespace Shared.ViewModel
{
class AddedServicesViewModel
{
readonly IList<AddedServiceStatus> source;
public ObservableCollection<AddedServiceStatus> ViewAddedServices { get; private set; }
public AddedServicesViewModel()
{
source = new List<AddedServiceStatus>();
CreateAddedServicesCollection();
}
void CreateAddedServicesCollection()
{
source.Add(new AddedServiceStatus
{
BusinessName = "Duck's Duct Cleaning"
});
source.Add(new AddedServiceStatus
{
BusinessName = "Rodney's Home Repair"
});
ViewAddedServices = new ObservableCollection<AddedServiceStatus>(source);
}
}
}
PastOrderViewModel :
using Shared.Models;
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Text;
namespace Shared.ViewModel
{
class PastOrderViewModel
{
readonly IList<PastOrderStatus> source;
public ObservableCollection<PastOrderStatus> ViewPastOrders { get; private set; }
public PastOrderViewModel()
{
source = new List<PastOrderStatus>();
CreatePastOrderCollection();
}
void CreatePastOrderCollection()
{
source.Add(new PastOrderStatus
{
BusinessName = "Karen's Magnificent Dog Grooming"
});
source.Add(new PastOrderStatus
{
BusinessName = "Harry's In Home Haircuts"
});
source.Add(new PastOrderStatus
{
BusinessName = "Shelly's Floral Arrangements"
});
ViewPastOrders = new ObservableCollection<PastOrderStatus>(source);
}
}
}
You could also bind a ViewModel to each CollectionView separately.
like:
<CollectionView ItemsSource="{Binding ViewAddedServices}">
<CollectionView.BindingContext>
<viewmodels:AddedServicesViewModel/>
</CollectionView.BindingContext>
...
</CollectionView>
<CollectionView ItemsSource="{Binding ViewPastOrders}">
<CollectionView.BindingContext>
<viewmodels:PastOrderViewModel/>
</CollectionView.BindingContext>
...
</CollectionView>
You can't have two ViewModels binding to a SingleView. (as far a I know)
I see that the DataTemplate in both Collections are the same..... there are many ways to refactor....
You could create two CustomView one with the AddedServicesViewModel and the other with PastOrderViewModel
You can merge the two ViewModels into one, and create a CustomView that it's the collection.
Another thing that I see that It could not work is that you can't have a more than one View Nested in a ScrollView
<ScrollView>
<StackLayout> /* Or any other Layout, Grid, Absolute, Flex etc... */
</StackLayout>
</ScrollView>
Another thing is that a CollectionView with orientation vertical in a ScrollView maybe it won't behave as you expect, since the CollectionView with orientation vertical it has Scroll
Two CollectionViews with orientation vertical in the same View it should have a Height, I would do something like this
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="1*"/>
<RowDefinition Height="1*"/>
</Grid.RowDefinitions>
<CollectionView Grid.Row="0" ItemsSource="{Binding ViewQuoteStatus}"> ... </CollectionView>
<CollectionView Grid.Row="1" ItemsSource="{Binding ViewAddedServices}"> ... </CollectionView>
</Grid>
or if you create a custom view (custom control)
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="1*"/>
<RowDefinition Height="1*"/>
</Grid.RowDefinitions>
<MyCustomCollectionView Grid.Row="0" ItemsSource="{Binding ViewQuoteStatus}"> ... </MyCustomCollectionView>
<MyCustomCollectionView Grid.Row="1" ItemsSource="{Binding ViewAddedServices}"> ... </MyCustomCollectionView>
</Grid>

I have a Content Page in which I want to show an invoice, for that I have two listviews.
The first one contains the name of the customer, the date and the total cost.
The thing is to get the total cost I have used Shell navigation with parameters and it works fine just not in the listview.
So here is my ViewModel
[QueryProperty(nameof(Total), "total")]
public class InvoiceViewModel : BindableObject
{
string _total;
public string Total
{
get => _total;
set
{
_total = Uri.UnescapeDataString(value ?? string.Empty);
OnPropertyChanged();
}
}
public InvoiceViewModel()
{
_oListOrders = new ObservableCollection<CrOrder>();
GetListCart();
}
private ApiService _apiService = new ApiService();
public List<Invoice> _oListCart = new List<Invoice>();
public ObservableCollection<CrOrder> _oListOrders;
public List<Invoice> ListCart
{
get => _oListCart;
set
{
_oListCart = value;
OnPropertyChanged();
}
}
private async void GetListCart()
{
// call database here
var customerId = Convert.ToInt32(CurrentPropertiesService.GetCustomer());
var customer = await _apiService.GetCustomerById(customerId, CurrentPropertiesService.GetToken());
_oListCart.Add(new Invoice
{
Name = customer.Data.Name,
Date = DateTime.UtcNow,
Total = Convert.ToDecimal(_total),
ListOrders = await GetListOrders()
});
}
private async Task<ObservableCollection<CrOrder>> GetListOrders()
{
// call database here
var cartId = Convert.ToInt32(CurrentPropertiesService.GetCart());
var orders = await _apiService.GetOrdersByCart(cartId, CurrentPropertiesService.GetToken());
ObservableCollection<CrOrder> collection = new ObservableCollection<CrOrder>(orders.Data);
return collection;
}
}
Here is what I have in my View
<ContentPage.Content>
<StackLayout BackgroundColor="#A7A7A7">

And on my ContentPage I don't have anything
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class InvoicePage : ContentPage
{
public InvoicePage()
{
InitializeComponent();
//BindingContext = new InvoiceViewModel();
}
}
So on my View I have put a label to check what I thought was happening. So the label shows right the total but when I use the ListView binging it doesn't work I don't know why it is null there.
As you can see the label works fine but where it sais "Monto Total" it shows nothing. Please help I don't know what is going on. Thanks.
EDIT
I tried naming the Total property different and then when I add my Invoice entity to my list I do this
Total = Convert.ToDecimal(TotalCart),
But it isn't working eitherway. I don't know why the first time it returns the value fine but the second it doesn't.
After debbuging I have realized when getting the total property that the first time when GetListCart is being called the value is null and the second time, when the label text is set it returns the correct value. Why is this happening?
I'm creating a Wizard to export DB tables into CSV.
I'm using Xceed Wizard and I need an Event in Next button. I want to validate the parameters before going to the next page when I click "Next", but I only can set CanSelectNextPage.

</Grid>
</xctk:WizardPage>
C# code:
private void tbBD1_TextChanged(object sender, TextChangedEventArgs e)
{
if (tbBDServer1.Text != "" && tbBDName1.Text != "" && tbBDUser1.Text != "")
{
PageBD1.CanSelectNextPage = true;
}
else
PageBD1.CanSelectNextPage = false;
}
Thanks.
Goal: When I enter a value in the textbox for Technician Name: I want it to update inside the DataModel and when I click to the NewCallView it will display inside the newcall View and when I click back to the DefaultViewModel it will appear still entered.
Problem: When i change between views the data resets.
I am going to provide my full code in an effort to figure out why my data keeps resetting. - I am still learning MVVM this is my first crack at it. I would normally make a 1 page application using code-behind. I am finding it hard to link up my Model to my ViewModels, and maybe I am calling (getting/setting) the properties incorrectly.
With regards to the code behind for each of my Views I did not alter it at all from its creation, I only worked in the Xaml.

I'm currently developing a plugin for Revit (BIM software) and I'm, trying to use WPF and Caliburn.Micro to show a window/dialog when I press a button of the plugin.
So like in the documentation, I have a bootstrapper:
public class Bootstrapper : BootstrapperBase
{
public Bootstrapper()
{
Initialize();
}
protected override void OnStartup(object sender, StartupEventArgs e)
{
DisplayRootViewFor<LocationPopupViewModel>();
}
}
}
A simple testing ViewModel:
namespace ExternalForms.ViewModels
{
public class LocationPopupViewModel : Screen
{
private int _horizontalLength;
private int _verticalLength;
public int HorizontalLength
{
get
{
return _horizontalLength;
}
set
{
_horizontalLength = value;
NotifyOfPropertyChange(() => HorizontalLength);
}
}
public int VerticalLength
{
get
{
return _verticalLength;
}
set
{
_verticalLength = value;
NotifyOfPropertyChange(() => VerticalLength);
}
}

And of course the window that I want to show:

The function that is trying to show the window:
private void SetBoundingBox()
{
IWindowManager windowManager = new WindowManager();
LocationPopupView locationPopup = new LocationPopupView();
windowManager.ShowWindow(locationPopup, null, null);
}
But when I try to open the dialog in Revit, a window with an error pops up:
UPDATE:
My current project structure looks like this:
Assembly "UI" takes care of all the internal UI elements in Revit (so the buttons in Revit, even though there is currently only one).
The current button in Revit calls the "Get3DBAG" assembly, who does some tasks and eventually calls the "Location" assembly, which calls the Windowmanager.showwindow() method for the WPF views, which are in the "ExternalForms" assembly.
You problem lies in the following line.
LocationPopupView locationPopup = new LocationPopupView();
You are attemping to initialize an instance of View, instead of ViewModel. You should replace this with following.
LocationPopupViewModel locationPopup = new LocationPopupViewModel();
Caliburn Micro would resolve the corresponding View by itself using the naming convention.
Update : Based on Comment
From your comment, it looks like your View/ViewModels are in a different assembly. In that scenario, you need to ensure the assembly is included while Caliburn Micro searches for Views. You can do so by overriding SelectAssemblies method in Bootstrapper.
protected override IEnumerable<Assembly> SelectAssemblies()
{
return new[]
{
Assembly.GetExecutingAssembly()
// Ensure your external assembly is included.
};
}

I'm trying to add a Clickable ListView-Cell, but I'm probably getting conflicts with the binding.
Each cell should be like a button navigating to a new Page including a given Object.
I already tried with "TapGestureRecognizer".
<ListView x:Name="ListView" HasUnevenRows="True" SelectionMode="Single" >
<ListView.ItemsSource>
<x:Array Type="{x:Type clients:MinRepresentation}">
<clients:MinRepresentation Id="123456789" PlannedStartTime="01-01-2019" PlannedEndTime="01-12-2019" />
<clients:MinRepresentation Id="555555555" PlannedStartTime="12-12-2019" PlannedEndTime="12-12-2019" />
</x:Array>
</ListView.ItemsSource>
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid Padding="5">
<Grid.GestureRecognizers>
<TapGestureRecognizer Command="{Binding OrderDetailsCommand}"/>
</Grid.GestureRecognizers>

[Cell-Template]
</Grid>
</ViewCell>

Got the easy solution...
XAML:
<ListView HasUnevenRows="True" SelectionMode="Single" ItemsSource="{Binding VisibleOrders}" ItemSelected="OnListViewItemSelected" ItemTapped="OnListViewItemTapped"/>
ViewModel:
public IList<MinRepresentation> VisibleOrders { get; private set; }
void OnListViewItemSelected(object sender, SelectedItemChangedEventArgs e)
{
MinRepresentation selectedItem = e.SelectedItem as MinRepresentation;
}
void OnListViewItemTapped(object sender, ItemTappedEventArgs e)
{
MinRepresentation tappedItem = e.Item as MinRepresentation;
}
