I am building a C# WPF app. My app Contains ListView with Multiple Column. I added column and binding in Listview with XAML

XML

<ListView x:Name="receiptList" HorizontalAlignment="Left" Height="209.987" VerticalAlignment="Top" Width="645" Margin="111,135.748,0,0" IsEnabled="False"  >
                           <ListView.View>
                               <GridView>
                                   <GridViewColumn Header="ReceiptID" Width="60" DisplayMemberBinding="{Binding ReceiptID}"/>
                                   <GridViewColumn Header="ItemNo" Width="50" DisplayMemberBinding="{Binding ItemNo}"/>
                                   <GridViewColumn Header="ItemName" Width="240" DisplayMemberBinding="{Binding ItemName}"/>
                                   <GridViewColumn Header="PackingSize" Width="100" DisplayMemberBinding="{Binding PackingSize}"/>
                                   <GridViewColumn Header="Quantity"  Width="50" DisplayMemberBinding="{Binding Quantity}"/>
                                   <GridViewColumn Header="Price"  Width="50" DisplayMemberBinding="{Binding Price}"/>
                                   <GridViewColumn Header="ExpiryDate"  Width="100" DisplayMemberBinding="{Binding ExpiryDate}"/>
                               </GridView>
                           </ListView.View>
                       </ListView>

Now with help of button i add rows in Listview:

C#

private void addItems_Click(object sender, RoutedEventArgs e)
        {
            
            AddItems addItems = new AddItems(hhk,2,"ABC","36X63",3,opop,"22-11-2014");
            receiptList.Items.Add(addItems);
        }

AddItems Class:

C#

class AddItems
    {



        public int ReceiptID { get; set; }
        public int ItemNo { get; set; }

        public String ItemName { get; set; }
        public String PackingSize { get; set; }
        public int Quantity { get; set; }
        public float Price { get; set; }
        public String ExpiryDate { get; set; }

        public AddItems()
        {

        }

        public AddItems(int oid, int itNo, string itName, string itSize, int qua, float pri, String eDate)
        {
            this.ReceiptID = oid;
            this.ItemNo = itNo;
            this.ItemName = itName;
            this.PackingSize = itSize;
            this.Quantity = qua;
            this.Price = pri;
            this.ExpiryDate = eDate;
        }



    }

Now i want to add a method which counts how many items are added in AddItems and also i want to retrieve items from AddItems with the help of loop

I don't understand. AddItems is just one item in the list. You are adding the items to receiptList.Items - this is your collection. To get the count query receiptList.Items.Count. BTW I would encourage you to study MVVM pattern, it goes very well with WPF.

Solution 1

Try this

C#

//For Item Count
       public int ItemAdd()
       {
           return listView1.Items.Count;
       }

       //Get Item
       public void  GetItem()
       {
           foreach(ListViewItem lst in  listView1.Items)
               {
                   var x = lst.Content;
               }
       }

Solution 2

how about you count in reCieptList like:

C#

private int Count()
 {
    var item = (from i in recieptList select i).ToList();
    return item.Count();
 }

hope that is what you want, if not then sorry.

I'd suggest to read it: ListView, data binding and ItemTemplate[^]
There you'll find a sample code which uses List of custom class. You need exactly the same!

Here is similar question: http://stackoverflow.com/questions/13647704/listview-binding-to-list-of-custom-class-containing-dictionnary[^]
