Label convert findcontrol

I am not very experienced and perhaps I am asking a stupid question. I'm trying to delete a row inside this gridview. To do this, I call a method deleteDettagliDocument(id_row) to perform a DELETE from my DB. This method takes an integer as parameter but the control is a Label and I can't cast it properly. Here's my code. 

protected void grdContact_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
    bool result;
    DboDocument objdbo = new DboDocument();
    InvoiceDetails ID = new InvoiceDetails();
    List<InvoiceDetails> app = (List<InvoiceDetails>)Session["lst_details"];
    int id_row = (Label)grdContact.Rows[e.RowIndex].FindControl("lblId_Row"); // Error!
    app.RemoveAt(e.RowIndex);
    Session["lst_details"] = app;
    FillGrid();
    CalculateTotal();
    result = objdbo.deleteDocumentDetails(id_row);
}

You are trying to assign Label to int,

Label lbl = grdContact.Rows[e.RowIndex].FindControl("lblId_Row") as Label;
if(lbl != null)
{
   int id_row = int.Parse(lbl.Text);
}
