推荐答案

Label MyTextBox = gvNotes.Rows[e.NewEditIndex].FindControl("lblID") as Label;

protected void gvNotes_RowEditing(object sender, GridViewEditEventArgs e)
    {
        try
        {
            if (gvNotes.EditIndex == -1)
            {
                gvNotes.EditIndex = e.NewEditIndex;

                Label lblID = (Label)gvNotes.Rows[e.NewEditIndex].FindControl("lblID");
                BindNotesGrid();

            }
            // this.EnableViewState = true;
        }
        catch (Exception ex)
        {
            //Page.ClientScript.RegisterStartupScript(base.GetType(), "My startupscript", cs.message("Problem loading page,please try again after sometime"));
            Page.ClientScript.RegisterStartupScript(base.GetType(), "My startupscript", cs.message(ex.Message.ToString()));
        }

}

还是同样的问题.
