GridView RowUpdating is not returning all items in the NewValues.Item array

I have a gridview with about 15 or so columns, all of which are template fields. Most of the cells contain a single textbox, but some of them have multiple textboxes. During the gridview's RowUpdating event I am using e.NewValues.Item(n) to loop through all the values returned from the gridview. The problem is, I'm only receiving the values that are coming from the single-element cells, and I can't find the values from the textboxes in the multiple-element cells.

I'm receiving this error:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

That tells me they're not even in the array. In the code below, the streets are all coming from the same cell, but they are being skipped (which I can tell when I print out the values in the lblTemp at the end).
Private Sub gvCompanies_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles gvCompanies.RowUpdating

    Dim intID As Integer = e.Keys(0)

    Dim strName As String = e.NewValues.Item(0)

    Dim strTicker As String = e.NewValues.Item(1)

    Dim strLocation As String = e.NewValues.Item(2)

    Dim strType As String = e.NewValues.Item(3)

    Dim strStreet1 As String = e.NewValues.Item(4)

    Dim strStreet2 As String = e.NewValues.Item(5)

    Dim strStreet3 As String = e.NewValues.Item(6)

    Dim strStreet4 As String = e.NewValues.Item(7)

    Dim strCity As String = e.NewValues.Item(8)

    Dim strState As String = e.NewValues.Item(9)

    Dim strZip As String = e.NewValues.Item(10)

    Dim strCountry As String = e.NewValues.Item(11)

    Dim strPhone As String = e.NewValues.Item(12)

    Dim strFax As String = e.NewValues.Item(13)

    Dim strClass As String = e.NewValues.Item(14)

    Dim strExecutives As String = e.NewValues.Item(15)

    Dim strIndustry1 As String = e.NewValues.Item(16)

    Dim ...
 

    lblTemp.Text = "ID = " & intID & _

    "<br />Name = " & strName & _

    "<br />Ticker = " & strTicker & _

    "<br />Location = " & strLocation & _

    "<br />Type = " & strType & _

    "<br />Street1 = " & strStreet1 & _

    "<br />Street2 = " & strStreet2 & _

    "<br />Street3 = " & strStreet3 & _

    "<br />Street4 = " & strStreet4 & _

    "<br />City = " & strCity & _

    "<br />State = " & strState & _

    "<br />Zip = " & strZip & _

    "<br />Country = " & strCountry & _

    "<br />Phone = " & strPhone & _

    "<br />Fax = " & strFax & _

    "<br />Class = " & strClass & _

    "<br />Executives = " & strExecutives & _

    "<br />Industry1 = " & strIndustry1

    ...
 

End Sub

How many elements in e.NewValues?  What is the type for each of the e.NewValues.Item(index)?

There are 16 template field columns in my gridview, 3 of which have multiple textboxes, and 13 of which contain a single textbox.

There are 13 elements in e.NewValues, because it is throwing the error on e.NewValues(13) which is the 14th element. As for the types, they are all <asp:textbox> elements except State which is <asp:dropdownlist>.

Here are all the textboxes in the row that I need returned:

        Dim strName As String = e.NewValues.Item(0)
        Dim strTicker As String = e.NewValues.Item(1)
        Dim strLocation As String = e.NewValues.Item(2)
        Dim strType As String = e.NewValues.Item(3)
        Dim strStreet1 As String = e.NewValues.Item(4)
        Dim strStreet2 As String = e.NewValues.Item(5)
        Dim strStreet3 As String = e.NewValues.Item(6)
        Dim strStreet4 As String = e.NewValues.Item(7)
        Dim strCity As String = e.NewValues.Item(8)
        Dim strState As String = e.NewValues.Item(9)
        Dim strZip As String = e.NewValues.Item(10)
        Dim strCountry As String = e.NewValues.Item(11)
        Dim strPhone As String = e.NewValues.Item(12)
        Dim strFax As String = e.NewValues.Item(13)
        Dim strClass As String = e.NewValues.Item(14)
        Dim strExecutives As String = e.NewValues.Item(15)
        Dim strIndustry1 As String = e.NewValues.Item(16)
        Dim strIndustry2 As String = e.NewValues.Item(17)
        Dim strIndustry3 As String = e.NewValues.Item(18)
        Dim strIndustry4 As String = e.NewValues.Item(19)
        Dim strIndustry5 As String = e.NewValues.Item(20)
        Dim strIndustry6 As String = e.NewValues.Item(21)
        Dim strIndustry7 As String = e.NewValues.Item(22)
        Dim strIndustry8 As String = e.NewValues.Item(23)
        Dim strIndustry9 As String = e.NewValues.Item(24)
        Dim strIndustry10 As String = e.NewValues.Item(25)
        Dim strRevenue As String = e.NewValues.Item(26)
        Dim strEBITDA As String = e.NewValues.Item(27)
        Dim strDescription As String = e.NewValues.Item(28)

The Streets are all in the same cell, the Phone and Fax are in the same cell, and the Industries are all in the same cell.

Let me know if I'm not making this clear enough.

I just noticed in the Gridview I'm using Eval instead of Bind on the values that are not being returned in the NewValues collection. Could this have something to do with it?

Good thing that you found it, because my crystal ball is in the shop getting fixed, and I wouldn't have known about Eval instead of Bind.   *BIG GRIN*
