Get value of cell in select row in nested gridview

Question

HI here is my problem

in my gridview1 I have template field with another gridview(gridview2).

in gridview2 I insert commandfield with delete button and I don't now how to write code for delete row.

My gridview1 I populate by objectdatasource and I write my DataAccessLayer in separate class. I also have  DeleteScanLogRow function but  need value from gridview2 cell . I try something like:

GridView grv2 = (GridView)GridView1.FindControl("GridView2");

string id =grv2.SelectedRow.Cells[0].Text;

            but this dosent work!!!

Here is my code from  DataAccessLayer class 

public class ScanLog

{

public int ScLogID { get; set; }

public int NalogID { get; set; }

public string tip{get;set;}

public string KatBR{get;set;}

public string FormatFrm{get;set;}

public string NazivFilma{get;set;}

public string Napomene{get;set;}

public string Bckp{get;set;}

//public string FilmID{get;set;}

public string ScanFor{get;set;}

public bool SkenTon{get;set;}

public List<ScanLogRow>ScanLogRow

{

get { return ScanLogDataAccessLayerRow.GetAllScanLogRow(this.ScLogID); }

}

}

public class ScanLogRow

{

public int ScLogRowID { get; set; }

public int ScLogID { get; set; }

public string datum { get; set; }

public int metraza { get; set; }

public int sfrm { get; set; }

public int efrm { get; set; }

public int cfrm { get; set; }

public decimal size { get; set; }

public string brrol { get; set; }

public string path { get; set; }
