Issue
I am new to xamarin forms and I am trying to make a project similar to what you can see in the next picture. photo
The thing I want to achieve is when I press an item from listView (which I already have with the items displayed) where I have all items I want to pass somehow the entire object to the tabPage so that I can see the description in one part and the opinions in the other page. I did some research but all the examples I saw uses MVVM and mine is more simple than that. Here you have the code.
--->Model
public class Item
{
public String name;
public String description;
public Double price;
public int stock;
public List<String> opinions;
public Item(String name, String description ,Double price, int stock, List<String> opinions)
{
this.name = name;
this.description = description;
this.price = price;
this.stock = stock;
this.opinions = opinions;
}
public override string ToString()
{
return this.name + " " + this.price + " $" + this.stock + " ud";
}
}
---> The event that takes me to the TabPage.
private async void parent_listView_ItemSelected(object sender, SelectedItemChangedEventArgs e)
{
//here maybe I should pass the object...
await Navigation.PushAsync(new TabPage());
}
---> Here you have both classes that are used inside the tabPage
public partial class Datos : ContentPage
{
//private string descriptionList;
public Datos()
{
InitializeComponent();
}
}
public partial class Opinions : ContentPage
{
public Opinions()
{
InitializeComponent();
}
}
The thing is that I don't know how to pass the object in a specific position from listView to both pages from tabPage in a easy way. I tried to pass both classes(Datos and Opinions) using TabPage constructor but it doesn't work. Here you have the code...
private async void parent_listView_ItemSelected(object sender, SelectedItemChangedEventArgs e)
{
await Navigation.PushAsync(new TabPage(new Datos(itemList[e.SelectedItemIndex] ), new Opinions(itemList[e.SelectedItemIndex] )));
}
Solution
SelectedItemChangedEventArgs
contains a reference to the selected object
private async void parent_listView_ItemSelected(object sender, SelectedItemChangedEventArgs e)
{
var item = (Item)e.SelectedItem;
await Navigation.PushAsync(new TabPage(item));
}
