                    OpenCustomDialog(strPageURL, 1050, 500, "Edit");
                    return false;
                }


                function OpenCustomDialog(dialogUrl, dialogWidth, 
dialogHeight, dialogTitle, 
dialogAllowMaximize, dialogShowClose) {

                    var options =
                     {
                         url: dialogUrl,
                         allowMaximize: dialogAllowMaximize,
                         showClose: dialogShowClose,
                         width: dialogWidth,
                         height: dialogHeight,
                         title: dialogTitle,
                         dialogReturnValueCallback: function (dialogResult) {
                             SP.UI.ModalDialog.RefreshPage(dialogResult)
                         }
                     } 
                    SP.UI.ModalDialog.showModalDialog(options);
                }
