        //theDataRowView.Row["Status"] == "Status";

        // Only look in data rows, ignore header and footer rows
        if (e.Item.ItemType == ListItemType.AlternatingItem ||
         e.Item.ItemType == ListItemType.Item)
         {
            // Get a data view row object so we can reference the data 
            // in the repeater by the bound field names      
            DataRowView theDataRowView = e.Item.DataItem as DataRowView;
            //theDataRowView.Row["Status"] == "Status";

            // Make sure we got the data row view before we try to use it
            if (theDataRowView != null)
            {
                // Get the value of status from the control that holds the value
                string theStatus = theDataRowView.Row["Status"].ToString();

                // Find the download link control
                LinkButton theLinkButtonDownload = e.Item.FindControl("LinkButton2")
             as LinkButton;

                if (theStatus.ToUpper() == "APPROVE")
                {
                    if (theLinkButtonDownload != null)
                    {
                        theLinkButtonDownload.Visible = true;
                    }
                }
                else
                {
                    if (theLinkButtonDownload != null)
                    {
                        theLinkButtonDownload.Visible = false;
                    }
                    }
                  }
                }


           }

因为您使用ToUpper ，请与大写字符串值进行比较，如下所示

Visible='<%#Convert.ToString(Eval("Status")).ToUpper() != "REJECT" %>'
