How do I add a data entry control inside of the ListView.

Question

I am trying to add a data entry control called Entry Cell inside of a ListView so that the user can enter data that I can save to the Database. I get the error... A value of type 'EntryCell' cannot be added to a collection or dictionary of type 'IList`1'.

 <ListView ItemsSource="{Binding sfDataGridModelCollection}">
                            <ListView.ItemTemplate>
                                <DataTemplate>

                                    <ViewCell>
                                        <HorizontalStackLayout>
 <EntryCell Label="Name"Placeholder="Enter name" Text="{Binding LocalName}" />
                                          
                                        </HorizontalStackLayout>
                                    </ViewCell>

                                </DataTemplate>
                            </ListView.ItemTemplate>
 </ListView>

Hello,

If you want to use EntryCell in the listview, you need to remove ViewCell, add EntryCell directly. You cannot nested use ViewCell and EntryCell.

  <ListView ItemsSource="{Binding sfDataGridModelCollection}">
                <ListView.ItemTemplate>
                    <DataTemplate>
                        <EntryCell Label="Name" Placeholder="Enter name" Text="{Binding LocalName}" />
                    </DataTemplate>
                </ListView.ItemTemplate>
            </ListView>

Here is a document about Data binding and MVVM, you can refer to it.

Best Regards,

The DataTemplate will have a grid as its top level a grid. Then define grid columns for each property of the object you are binding to. Then each control can be whatever you want ex. for a property that cannot be editted a Lable and for others an Entry or a ComboBox depending on what the property is.
