[RESOLVED] itemdatabound doubles total

The framework using is 3.5.

Situation: I have a page which I call a stored procedure that returns two results. I create a dataset and then from that create two dataviews which one can have multiple records.

Issue: During the rptInvoice_ItemDataBound of the repeater I am adding the amount value. The problem is it's always double what it should be. If I have one result with a total of $100 it shows $200. If I have two records each with $150 the total shown is $600. It's like its looping twice per row but only showing the row once.

Any thoughts on why my total is double?

Here is my code.

Code:

---

    Dim cFn As clsFunctions = New clsFunctions
    Dim cEncDec As clsEncryptDecrypt = New clsEncryptDecrypt

    Private m_Total As Decimal

    Public Property Total() As Decimal
        Get
            Return m_Total
        End Get
        Set(ByVal Value As Decimal)
            m_Total = Value
        End Set
    End Property

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not IsPostBack Then
              '......
                sbFillPage(ID)
                lblTotal.Text = Total
        End If
    End Sub

    Private Sub sbFillPage(ByVal iPaypalTransactionID As Integer)
        'Get information for receipt page
        Dim dsReceiptInfo As DataSet = cFn.fnGetReceiptInfo(iPaypalTransactionID)
        Dim dvPaypalInfo As DataView = New DataView(dsReceiptInfo.Tables(0))
        Dim dvInvoiceInfo As DataView = New DataView(dsReceiptInfo.Tables(1))

        If dvPaypalInfo.Count > 0 Then
            lblOrderNum.Text = iPaypalTransactionID
            lblOrderDateTime.Text = dvPaypalInfo(0)("xxx")
            lblFirstName.Text = dvPaypalInfo(0)("xxx")
            lblLastName.Text = dvPaypalInfo(0)("xxx")
        End If

        lblInvoiceCount.Text = dvInvoiceInfo.Count

        rptInvoice.DataSource = dvInvoiceInfo
        rptInvoice.DataBind()

    End Sub

    Protected Sub rptInvoice_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rptInvoice.ItemDataBound
        If e.Item.ItemType = ListItemType.Header Then
            Total = 0
        End If

        If ((e.Item.ItemType = ListItemType.Item) _
                    OrElse (e.Item.ItemType = ListItemType.AlternatingItem)) Then
            Total += CType(e.Item.DataItem, DataRowView)("invoice_amt")
        End If
    End Sub

---

HTML Code:

---

<asp:Repeater ID="rptInvoice" runat="server" OnItemDataBound="rptInvoice_ItemDataBound">
            <HeaderTemplate><table>
            <tr>
                <th>Invoice</th>
                <th>Total</th>
            </tr></HeaderTemplate>
            <ItemTemplate>
                <tr>
                    <td><%# DataBinder.Eval(Container.DataItem, "invoice_id")%></td>
                    <td><%# Eval("invoice_amt", "{0:C}")%></td>
                </tr>
            </ItemTemplate>
            <FooterTemplate>
            </table>
            </FooterTemplate>
        </asp:Repeater>

Try 2 things.

1: Try deleting OnItemDataBound from your repeater.
2: If first doesn't help try deleting Handles rptInvoice.ItemDataBound From your procedure.


I'm not sure but it could be that both onItemDataBound in html and Handler event in vb is calling the function resulting in 2 call.

n3xus - Thanks. #2 did the trick.

Thanks for thanking me :D

Hello,

I have seen this issue a couple times, and in all honesty, it is a little annoying, I would have thought that Visual Studio should have been able to pick this up for you?!?
