Question

I am trying to retrieve data from SQL Server into my form. I am trying with the below code. When I run this I get the first item or row but I am unable load the rest of the items into my listview . Can someone help to solve my issue?

Sub GetInvoiceDetails()
    Dim Inv As New petClass
    Dim dt As DataTable = Inv.GetInvoiceDetailsbyNo(txtInvoiceNo.Text)
    If dt.Rows.Count > 0 Then
        For Each row In dt.Rows
            srno += 1
            Dim lstitem = Lstview.Items.Add(srno)
            lstitem.SubItems.Add(dt.Rows(0).Item("ItemName").ToString)
            lstitem.SubItems.Add(dt.Rows(0).Item("SellingPrice".ToString)).ToString()
        Next
    End If
    'clearcontrols
End Sub

You’re always using the first row in the DataTable with dt.Rows(0).

Instead:

For Each row As DataRow In dt.Rows
    srno += 1
    Dim lstitem = Lstview.Items.Add(srno)
    lstitem.SubItems.Add(row.Field(of String)("ItemName"))
    lstitem.SubItems.Add(row.Field(Of String)("SellingPrice"))
Next
