Binding question (newbie)

Question

Hi

My UpcomingJobsPage is bound to UpcomingJobsViewModel and has the xaml as below at the end.

The RefreshView is bound to UpcomingJobsViewModel and calls command LoadDataCommand to load data into the ObservableCollection UpcomingJobsList. The listview is bound to UpcomingJobsList. Pretty standard stuff.

My question is how in general can I choose to bind my UpcomingJobsPage view elements to either UpcomingJobsViewModel properties or UpcomingJobsList properties? For instance in below code I need the 'From' to be coming from UpcomingJobsList but it says;

Thanks

Regards

 <ContentPage.Content>  
        <Grid>  
            <RefreshView x:DataType="viewmodels:UpcomingJobsViewModel" Command="{Binding LoadDataCommand}" IsRefreshing="{Binding IsBusy, Mode=TwoWay}">  
                <ListView x:Name="listView" ItemsSource="{Binding UpcomingJobsList}" >  
                    <ListView.ItemTemplate>  
                        <DataTemplate >  
                            <ViewCell>  
                                <ViewCell.View>  
                                    <Grid >  
                                        <Label Text="{Binding From}" />  
                                    </Grid>  
                                </ViewCell.View>  
                            </ViewCell>  
                        </DataTemplate>  
                    </ListView.ItemTemplate>  
                </ListView>  
            </RefreshView>  
        </Grid>  
    </ContentPage.Content>  

Answer 1

"From" is a member of UpcomingJobsList model, so you should set the ListView "x:DataType" to UpcomingJobsList model.

Answer 2

Hello,
Welcome to our Microsoft Q&A platform!

As alessandrocaliaro said, you could set the ListView "x:DataType" to UpcomingJobsList model, like the code following:

<DataTemplate x:DataType=" the model you used in UpcomingJobsList">  

For more information, you can refer to https://learn.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/data-binding/compiled-bindings
