b.title = Convert.ToString(g.Rows[e.RowIndex].FindControl("Title"));
b.price = Convert.ToDouble(g.Rows[e.RowIndex].FindControl("Price"));
// b.rec = Convert.ToString(g.Rows[e.RowIndex].FindControl("Date_of_reciept"));
b.ed = Convert.ToString(g.Rows[e.RowIndex].FindControl("Edition"));
b.bill = Convert.ToString(g.Rows[e.RowIndex].FindControl("Edition"));
b.cre_by = Convert.ToString(g.Rows[e.RowIndex].FindControl("Edition"));

I have also tried to do update by following way
protected void gv1_updating(object sender, GridViewUpdateEventArgs e)
{
GridView g = (GridView)sender;
abc a = new abc();
DataTable dt = new DataTable();
try
{
a.cd_Id = Convert.ToInt32(g.DataKeys[e.RowIndex].Values[0].ToString());
//TextBox b = (TextBox)g.Rows[e.RowIndex].Cells[0].FindControl("cd_id");
TextBox c = (TextBox)g.Rows[e.RowIndex].Cells[2].FindControl("cd_name");
TextBox d = (TextBox)g.Rows[e.RowIndex].Cells[3].FindControl("version");
TextBox f = (TextBox)g.Rows[e.RowIndex].Cells[4].FindControl("company");
TextBox h = (TextBox)g.Rows[e.RowIndex].Cells[6].FindControl("created_by");
TextBox i = (TextBox)g.Rows[e.RowIndex].Cells[8].FindControl("modified_by");
//a.cd_Id = Convert.ToInt32(b.Text);
a.cd_name = c.Text;
a.ver = d.Text;
a.comp = f.Text;
a.cre_by = h.Text;
a.mod_by = i.Text;
a.updateDigi(a);
g.EditIndex = -1;
dt = a.GetAllDigi();
g.DataSource = dt;
g.DataBind();
}
catch(Exception ex)
{
throw (ex);
}
finally
{
dt = null;
a = null;
g = null;
}
