Default atlas and web shop

I created a page to edit products. for some reason it is not seeing that i have an item in the fileupload control box. IT just says cannot insert null item into picturesurlsmall. If i remove atlas and the update panel from my page it works fine.

I used more of the code that was already in the add products vb file

here is my vb code i can get you my ASP.net code if you need it.
Protected Sub DetailsView_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewUpdateEventArgs) _
    Handles DetailsView1.ItemUpdating
        Dim dv As DetailsView = DetailsView1

        '        '        ' Find the Selected Category Name ID Value

        Dim CatIDup As Integer = CType(dv.FindControl("ddlCat"), DropDownList).SelectedValue

        '        ' sdsevents.UpdateParameters.Clear()
        sdsGetProduct.UpdateParameters.Add("categoryId", CatIDup)
            ' First. try to save the images
            Dim theFileUpload As FileUpload = CType( _
                  DetailsView1.FindControl("FileUpload1"), FileUpload)
            If theFileUpload.HasFile Then
                Dim fileNameSmall As String = "~/Images/Products/" & Guid.NewGuid.ToString()
                Dim fileNameMedium As String = "~/Images/Products/" & Guid.NewGuid.ToString()
                Dim fileNameLarge As String = "~/Images/Products/" & Guid.NewGuid.ToString()

                Dim theExtension As String = Path.GetExtension(theFileUpload.FileName)

                fileNameSmall &= theExtension
                fileNameMedium &= theExtension
                fileNameLarge &= theExtension
                ' Now resize the images
                Helpers.ResizeImage(Server.MapPath(fileNameLarge), _
                    Server.MapPath(fileNameSmall), 40)
                Helpers.ResizeImage(Server.MapPath(fileNameLarge), _
                    Server.MapPath(fileNameMedium), 100)
                Helpers.ResizeImage(Server.MapPath(fileNameLarge), _
                    Server.MapPath(fileNameLarge), 250)

                e.NewValues("PictureUrlSmall") = fileNameSmall
                e.NewValues("PictureUrlMedium") = fileNameMedium
                e.NewValues("PictureUrlLarge") = fileNameLarge
            End If

                   Catch ex As Exception
        End Try

    End Sub

Hi gtjr92,

I think this is a problem with Atlas and the UpdatePanel where the uploaded file isn't handled correctly.

Take a look here: http://www.nikhilk.net/AtlasM1Refresh.aspx

It discusses the problem and offers some work arounds (haven't tested them yet). If that doesn't help, searching Google for atlas upload file should give you some useful results.

Hope this helps,

Imar Spaanjaars
