GridView - Index was out of range.

I've got a GridView that's sorted by a stored procedure with
ROW_NUMBER:

PROCEDURE dbo.GetCalendar sByStatusIDPage d
(
@startRowIndex int,
@maximumRows int,
@statusID int
)
AS
SELECT pk_calendarID, fk_statusID, filename, barcode, received,
atpress, athandfinishing , shipped, reprint, status
FROM
(
SELECT pk_calendarID, fk_statusID, filename, barcode,
received, atpress, athandfinishing , shipped, reprint,
(SELECT status FROM Statuses WHERE Statuses.pk_sta tusID =
Calendars.fk_st atusID) as status,
ROW_NUMBER() OVER (ORDER BY received) AS RowRank
FROM Calendars
) AS CalendarsWithRo wNumbers
WHERE RowRank @startRowIndex AND RowRank <= (@startRowIndex +
@maximumRows) AND fk_statusID = @statusID

Here's the GridView:

<asp:GridView ID="GridView1" runat="server"
DataSourceID="C alendarsDataSou rce" AutoGenerateCol umns="False"
DataKeyNames="p k_calendarID" AllowPaging="Tr ue" PageSize="100">
<Columns>
<asp:BoundFie ld DataField="barc ode"
HeaderText="Bar code" SortExpression= "barcode" />
<asp:BoundFie ld DataField="rece ived"
HeaderText="Rec eived" SortExpression= "received" />
<asp:BoundFie ld DataField="atpr ess"
HeaderText="At Press" SortExpression= "atpress" />
<asp:TemplateFi eld>
<ItemTemplate >
<asp:CheckBox
ID="SelectCalen darCheckbox" runat="server" />
</ItemTemplate>
<HeaderTemplate >
<input id="chkAll"
onclick="javasc ript:SelectAllC heckboxes(this) ;" runat="server"
type="checkbox" />
</HeaderTemplate>
</asp:TemplateFie ld>
</Columns>
</asp:GridView>
<br />
<asp:Button ID="btnToHandFi nishing" runat="server"
Text="Move To 'At Hand Finishing' Status"
OnClick="btnToH andFinishing_Cl ick" /><br />
<asp:ObjectData Source ID="CalendarsDa taSource"
runat="server" SelectMethod="G etCalendarsBySt atusIDPaged"
TypeName="Calen darsBLL" EnablePaging="T rue"
SelectCountMeth od="TotalNumber OfCalendarsBySt atusID">
<SelectParamete rs>
<asp:Paramete r DefaultValue="2 "
Name="statusID" Type="byte" />
</SelectParameter s>
</asp:ObjectDataS ource>

Then, I've got a button to take selected rows (via checkboxes in a
TemplateField) and do something with them in the database:

protected void btnToHandFinish ing_Click(objec t sender, EventArgs e)
{
// Copy the items in the Rows collection into an array.
GridView gv1 = (GridView)Login View1.FindContr ol("GridView1") ;
GridViewRow[] rowArray = new GridViewRow[gv1.Rows.Count];
gv1.Rows.CopyTo (rowArray, 0);

// Iterate though the array and display the value in the first
cell of the row.
foreach (GridViewRow row in rowArray)
{
bool result =
((CheckBox)row. FindControl("Se lectCalendarChe ckbox")).Checke d;
if (result)
{
byte fk_statusID = 3;
DateTime athandfinishing = DateTime.Now;
int pk_calendarID =
(int)gv1.DataKe ys[row.RowIndex].Value;
Label1.Text += gv1.DataKeys[row.RowIndex].Value + " " +
row.Cells[1].Text + "<br />";
// Get filename
string filename =
methods.GetCale ndarFilename(pk _calendarID);
methods.UpdateC alendarAtHandFi nishing(fk_stat usID,
athandfinishing , pk_calendarID);
// Move Files to "READY_TO_PRINT " folder
string from = @"C:\HTTPPush\R EADY_TO_PRINT\" +
filename;
string to = @"C:\HTTPPush\P ROCESSED\" + filename;
// File.Move(from, to);
}
gv1.DataBind();
}
}

If I run it without the 'int pk_calendarID =
(int)gv1.DataKe ys[row.RowIndex].Value;' line, it runs fine, and
displays the appropriate values. But if I run it with the
pk_calendarID line it fails with :

the collection.

I have a gridview that is populated via page_load. I can get the delete to work but get an error after it deletes. The error is below the index value that is returned is the one that is deleted so that is why I think I get an error. Any help would be great. I am in the process of moving from classic ASP to .NET so i am not well versed yet. Index was out of range. Must be non-negative and less than the size of the collection....
