RowUpdating in gridview

Question

Hii frnds thnx for reply on my last post. i sort out the issue, while using datakeys.
but now facing problem in row updating.

cant able to assign values which will be updated.
i using layers (BusinessEntity,Logic nd dataaccess)
so here is my code

 binding data in gridview
 private void BindGrid()
    {
        UserInfoBE objUserBE = new UserInfoBE();
       
        objUserBE.EmailId = lblID.Text;
        UserInfoBL objUserBL = new UserInfoBL();
        GridView1.DataSource = objUserBL.SelectAllUserInfo(objUserBE);
        GridView1.DataBind();
    }
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        UserInfoBE objUserBE = new UserInfoBE();
           
        objUserBE.EmailId =((TextBox)GridView1.Rows[e.RowIndex].Cells[2]).Text;
        objUserBE.FirstName = ((TextBox)GridView1.Rows[e.RowIndex].Cells[2]).Text;
        objUserBE.LastName = ((TextBox)GridView1.Rows[e.RowIndex].Cells[2]).Text;
        objUserBE.Mobile = ((TextBox)GridView1.Rows[e.RowIndex].Cells[2]).Text;
        objUserBE.Address =((TextBox)GridView1.Rows[e.RowIndex].Cells[2]).Text;
      


        UserInfoBL objUserBL = new UserInfoBL();
      
            if (objUserBL.InsertUpdateUserInfo(objUserBE) > 0)
            {
                GridView1.EditIndex = -1;
                BindGrid();
                lblmsg.Text = "Update";
            }
      
    }
    protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        GridView1.EditIndex = e.NewEditIndex;
        BindGrid();
    }
