Here group binding is done and the products are listed under the corresponding dealers. I want to multiply the price and quantity of each products under one dealer and store it in a List_model-OrderModel when the View Order button is clicked. I am not able to access the quantity value in the custom stepper text in my cs file.
I tried var qty = stepper.Text. but the name stepper is not coming. CustomStepper and Stepper is coming the dropdown.
This is my custom stepper:
/*Created this class to make a custon stepper to add quantity */
public class CustomStepper : StackLayout
{
Button PlusBtn;
Button MinusBtn;
Label QtyLbl;
public static readonly BindableProperty TextProperty =
BindableProperty.Create(
propertyName: "Text",
returnType: typeof(int),
declaringType: typeof(CustomStepper),
defaultValue: 0,
defaultBindingMode: BindingMode.TwoWay);
public int Text
{
get { return (int)GetValue(TextProperty); }
set { SetValue(TextProperty, value); }
}
public CustomStepper()
{
PlusBtn = new Button { Text = "+", WidthRequest = 23, HeightRequest = 25, FontSize = 11, BackgroundColor = Color.LightGray, Padding = 0};
MinusBtn = new Button { Text = "-", WidthRequest = 23, HeightRequest = 25, FontSize = 11, BackgroundColor = Color.LightGray, Padding = 0};
Orientation = StackOrientation.Horizontal;
PlusBtn.Clicked += PlusBtn_Clicked;
MinusBtn.Clicked += MinusBtn_Clicked;
QtyLbl = new Label { FontSize = 11, VerticalTextAlignment = TextAlignment.Center, HorizontalTextAlignment = TextAlignment.Center, WidthRequest = 20 };
QtyLbl.SetBinding(Entry.TextProperty, new Binding(nameof(Text), BindingMode.TwoWay, source:this));
Children.Add(MinusBtn);
Children.Add(QtyLbl);
Children.Add(PlusBtn);
}
private void MinusBtn_Clicked(object sender, EventArgs e)
{
if (Text > 0)
Text--;
}
private void PlusBtn_Clicked(object sender, EventArgs e)
{
if (Text < 10)
Text++;
}
}
This is my Model class code:
public partial class AllProductListview
{
public decimal PK { get; set; }
public decimal VendorFK { get; set; }
public string Vendorname { get; set; }
public string distance { get; set; }
public string NameE { get; set; }
public string NameC { get; set; }
public float SalesPrice { get; set; }
public int Quantity { get; set; }
public decimal DChargeMode { get; set; }
public string VatForm { get; set; }
public float TotalAmount { get; set; }
public string DeliveryCharge { get; set; }
}
public class OrderModel
{
public int PK { get; set; }
public int VendorFK { get; set; }
public string NameE { get; set; }
public string NameC { get; set; }
public float SalesPrice { get; set; }
public int DChargeMode { get; set; }
public string VatForm { get; set; }
public string DeliveryCharge { get; set; }
public int Quantity { get; set; }
public float TotalAmount { get; set; }
public string Delete { get; set; }
}
I have this in my button click in the corresponding cs file:
private async void viewOrderBtn_Clicked(object sender, EventArgs e)
{
var item = (Button)sender;
/*item.BindingContext contains all the values [whn i did step by step debugging] as in AllProductListview..now I have to put it in a loop and calculate the total by multiplying the price and quantity and store it in OrderModel by adding the record into the Orderlist*/
var productList = item.BindingContext as AllProductListview;
List<OrderModel> Orderlist = new List<OrderModel>();
}
My xaml file :

Update : I have attached the pic of my debug window. Please walk me from here. I could bring the data from the xaml. I'm new to xamarin forms. No idea how to go from here.
private async void viewOrderBtn_Clicked(object sender, EventArgs e)
{
/*item.BindingContext contains all the values [whn i did step by step *debugging] as in AllProductListview..now I have to put it in a loop and *calculate the total by multiplying the price and quantity and store it in *OrderModel by adding the record into the Orderlist*/
var item = (Button)sender;
var itemobj = item?.BindingContext as AllProductListview;
List<OrderModel> Orderlist = new List<OrderModel>();
int ID = Convert.ToInt32(itemobj.PK); //showing no value assigned
int vendorfk = Convert.ToInt32(itemobj.VendorFK); //showing no value assigned
float price = itemobj.SalesPrice; //showing no value assigned
int quantity = itemobj.Quantity; //showing no value assigned
float total = price * quantity;
}
