您是否尝试在gridview上使用预渲染来确定它是什么日期并在RowEditing之前锁定所有内容？

Have you tried using a pre-render on the gridview to determine what day it is and lock everything prior to the RowEditing?

protected void GridView2_PreRender(object sender, EventArgs e)
       {
           if (this.GridView2.EditIndex != -1)
           {
               GridViewRow row = GridView2.Rows[GridView2.EditIndex];
               string date=DateTime.Now.ToString();
               string uploadeddate = Session["UploadedDate"].ToString();

               // everything starts as READ ONLY except for Comments. Then determine what the user can edit based on access rights

               if (row.RowType == DataControlRowType.DataRow)
               {
                   ImageButton button= (ImageButton)row.FindControl("imgbtnEdit"); button.Enabled = false;

                 if (uploadeddate == date)
                 {
                   button.Enabled = true;
                   BtnExport.Visible = true;
                   GridView2.EditIndex = e.NewEditIndex;
                   BindData();
                 }
               }
           }
       }
