foreach (GridViewRow chkrow in gdvReceivedLetter.Rows)
            {
                CheckBox chk = (CheckBox)chkrow.FindControl("chkDelete");
                if (chk != null && chk.Checked)
                {
                    Page.ClientScript.RegisterStartupScript(this.GetType(), "", "alert('CHECKEDDDDD');", true);   
                }
            }

Answer 1

你在哪里

DataGridView1.EndEdit();

因为曾经，用户检查过它，在发出 EndEdit() 之后，它会保存到数据源中......
