Im getting a NullReferenceException when I goto add a product to my cart, i get the error when i come to this part
cart.AddProduct(productnumber, name, price, prodQty, knobColor, finishColor)
I use extremely similar code in another one of my projects and do not come across this problem, I have also researched it for a while and still came across no soltuion.
Protected Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
Dim cart As New Cart
cart = Session("Cart")
Dim flag As Integer = 1
Dim finishColor As String = ""
Dim knobColor As String = ""
Dim prodQty As Integer = 0
Dim price As Decimal = 0
Dim name As String = ""
Dim productnumber As Integer = 0
If txtQty.Text <> "" And IsNumeric(txtQty.Text) Then
prodQty = txtQty.Text
flag = 0
Else
lblError.Text = "Please enter a numeric quantity."
Return
End If
productnumber = prodID
name = lblName.Text
price = lblPrice.Text
prodQty = txtQty.Text
finishColor = DDFinish.SelectedItem.Text
knobColor = DDKnob.SelectedItem.Text
cart.AddProduct(productnumber, name, price, prodQty, knobColor, finishColor)
Session("Cart") = cart
Any help is appreciated!
