Forms Data Controls :: Get Two Values Of A Gridview For Separate Operations?

i am displaying a gridview from db(SQL2005), which display leave table where employee apply leave and submit to admin. Viewing the leave table in gridview the admin sanction or rejected their leave request, by clicking the check box displays on each gridview rows and click on sanction or rejected button.

here i am sending SMS to the employee number displaying in the gridview (taking the employee phone number and send SMS).. this i have done using bulk SMS services, i have taken the number using the following
if check conditions...

but now what the problem is i have to delete the gridview rows.. i am using the same employee phonenumber to delete the corresponding gridview, but if suppose the single employee applied for two or more leave, the gridview display all leave for the single employee, the admin have sanction only one leave for that employee.. so if he checks the check box and click on OK button.. it have to delete the corresponding row as well as send SMS to the phonenumber of the employee.. Other leaves of the same employee display in the gridview.. i used the following coding

Protected Sub bttnsanction_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles bttnsanction.Click
Dim row As GridViewRow
Dim selection As New ArrayList()
For i As Integer = 0 To GridView1.Rows.Count - 1.........

I am using the Sno as primary key in leave table.. where i want to delete the corresponding row which sends SMS to employee number also the delete the row of corresponding Sno.. i have to get the corresponding gridview row sno in the delete store procedure..
