Get Data from Repeater Control

[jcas1411]

Okay, I have found a suggested C# solution that syntatically ported to VB.NET seemed to look right however getting a Null pointer exception when i try to get data from the control..

Dim details As New objFilingDetails
Dim item As RepeaterItem
        
For Each item In Repeater1.Items
        'the repeater contains datarow views, each row 3 textboxes, 1 label

       Dim dtrow As Data.DataRowView = CType(item.DataItem, Data.DataRowView)

'gets to here....mouse over in debug shows item.DataItem is Nothing
'however does show two items in Repeater1.Items

            details.Description = (CType(dtrow.Item("txtbx_Documents"), TextBox)).Text
            details.FAA_Advance = Decimal.FromOACurrency((CType(dtrow.Item("txtbx_FAAFee"), TextBox)).Text)
            details.Aero_Fee = Decimal.FromOACurrency((CType(dtrow.Item("txtbx_AeroFee"), TextBox)).Text)
            details.FAA_Number = (CType(dtrow.Item("lbl_FAANo"), Label)).Text

            objFiling.Details.Add(details)

Next

Using a user control as basically 1 label 1 multiline textbox and 2 textboxes
wrote a ItemBound function in the forms codebehind and a setData in the code behind for the control...

 Private Sub Repeater1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles Repeater1.ItemDataBound
        If (e.Item.ItemType = ListItemType.Item) Then
            CType(e.Item.FindControl("filing"), _
               filingControl).SetData(CType(e.Item.DataItem, _
               Data.DataRowView), False)
        End If
        If (e.Item.ItemType = ListItemType.AlternatingItem) Then
            CType(e.Item.FindControl("filing"), _
               filingControl).SetData(CType(e.Item.DataItem, _
               Data.DataRowView), True)
        End If

    End Sub


 Public Sub SetData(ByVal dr As Data.DataRowView, ByVal IsAlternating As Boolean)

        Me.lbl_FAANo.Text = dr("FAA_Number")
        Me.txtbx_Documents.Text = dr("Description")
        Me.txtbx_FAAFee.Text = FormatCurrency(dr("FAA_Advance"), 2)
        Me.txtbx_AeroFee.Text = FormatCurrency(dr("Aero_Fee"), 2)

        If IsAlternating Then
            Panel1.BackColor = Drawing.Color.LightGoldenrodYellow
        End If


    End Sub

............... ..sets great.......... ..just can't seem to figure out how to get the data back from the textboxes (user edits) or label without this Null Pointer Exception

Sweet, figured out my own problem after a little sleep. Basically my repeater didn't contain a datarowview object, it contained a UserControl that contained the datarowview object.... so my solution, add a getData() function in my user control and return the object it contains. In the codebehind for the form find user control and assign it to an object...workes and is clean.

  Function GetData() As objFilingDetails
        Dim adetail As New objFilingDetails
        adetail.FAA_Number = Me.lbl_FAANo.Text
        adetail.Description = Me.txtbx_Documents.Text
        adetail.FAA_Advance = Convert.ToDecimal(Me.txtbx_FAAFee.Text.Trim("(", "$", ")"))
        adetail.Aero_Fee = Convert.ToDecimal(Me.txtbx_AeroFee.Text.Trim("(", "$", ")"))

        Return adetail
    End Function

'and in the codebehind
     Dim details As New objFilingDetails
        Dim item As RepeaterItem
        For Each item In Repeater1.Items

            details = CType(item.FindControl("filing"), filingControl).GetData()
            objFiling.Details.Add(details)

        Next
