hello there, my name is ade and i need help on a task, am working on project in vb.net. i have a listview on a form, the listview has 4 fixed columns and as many rows as possible based on user entries at the click several buttons. if a user clicks a garment button a row is inserted and it looks like this:

Desc,        Amount      Quantity    No. Piece
-----------------------------------------------
2pc suit      500           2           2

(inserting a garment with its cost, the quantity of garments brought and how many pieces makes that garment type)

when he clicks a color button another row is inserted now making the list view look like this:

Desc,            Amount          Quantity        No. Pieces
-----------------------------------------------------------
2pc suit          500               2               2
black

when he clicks a fabric button another row is inserted now making the list view look like this:

Desc,        Amount      Quantity    No. Pieces
------------------------------------------------
2pc suit      500           2           2
black
wool

The above mentioned tasks i can achieve, but now at the click of a button i need to generate a ticket or invoice along with some tags(short descriptive/details) report . Generating these tag is the issue, from the above you can see that two 2piece suit has been entered (inserted) and 2 items make up a 2pc suit( 2 piece suit) this implies 4 tags (that is 2piece times quantity 2).

these tags will carry name of item, color, fabric, amount and total quantity (listing it as 1of4,2of4,3of4 and 4of4).

something like this:

===================================================
= (1/4)  Due date 23/05/2017 User:2               =
= customer name: Tom Jones Contact No: 08023345677=
= 2pc Suit 500/blue/cotton                        =
===================================================

It gets more complicated when you now have something like this,

Desc,        Amount      Quantity    No. Pieces
-------------------------------------------------
2pc suit      500           2           2
black
wool
-------------------------------------------------
Shirt        200            1           1
blue
cotton
-------------------------------------------------
Shirt        200            1           1
white
cotton
-------------------------------------------------
Shirt        200            1           1
pink
cotton
-------------------------------------------------

Well... You're keeping a focus on a ListView control instead of data. I'm sorry, but this is wrong approach.

To spare you trouble i'd suggest to think about invoice as a set of objects:

invoice
    (
    invoice no.,
    date of sale,
    item on invoice
        (
          selled object /a garment in your case/,
          amount,
          price,
          etc.
        )
    ),
seller (seller no., name, etc.),
buyer (buyer no., name, etc.)

Every single object should be represented as a Class[^], which contains several properties. For example, Customer may be defined as:

VB.NET

Public Class Customer
	Private sName As String = String.Empty
	Private sContactNo As String = String.Empty
	
	Public Sub New()
		'default - empty constructor
	End Sub

	Public Sub New(ByVal _Name As String, ByVal _ContactNo As String)
		sName = _Name
		sContactNo = _ContactNo
	End Sub
	
	Public Property Name As String
		Get
			Return sName
		End Get
		Set (value As String)
			sName = value
		End Set
	End Property

	Public Property ContactNo As String
		Get
			Return sContactNo
		End Get
		Set (value As String)
			sContactNo = value
		End Set
	End Property
End Class

So, to create Customer object:

VB.NET

Dim cust As Customer = New Customer("Maciej Los", "0123654789")

I wan't to provide complete code, because it's your job. Conclusion is: you should start from basics:
Objects and classes in Visual Basic | Microsoft Docs[^]
Defining Classes (Visual Basic) | Microsoft Docs[^]

Good luck!
