]],
toolbar:[
],
Ondblclickrow:function () {
Selected = $ (' #tt '). DataGrid (' getselected ');
var index = $ (' #tt '). DataGrid (' Getrowindex ', selected);
$ (' #tt '). DataGrid (' BeginEdit ', index);
Progress ();
Taskpreempte (Selected.taskid);
}
});

$ (' #my_toolbar '). Appendto ('. Datagrid-toolbar ');

var dd = new Date ();
var D1 = dd.getfullyear () + "-" + (Dd.getmonth () +1) + "-1";
var d2 = dd.getfullyear () + "-" + (Dd.getmonth () +1) + "-" + dd.getdate ();
$ (' #qryStartDate '). Datebox (' SetValue ', D1); Set Datebox value
$ (' #qryEndDate '). Datebox (' SetValue ', D2); Set Datebox value
RefreshRpt2 ();

});

function RefreshRpt2 () {
var strstatcond = "B.region_name";
if ($ (' #qryCon '). attr ("value")!=100) {
param.sts = $ (' #qryCon '). attr ("value");
alert (param.sts);
}
Param.qrybegintime =$ (' #qryStartDate '). Datebox (' GetValue ');
alert (param.qrybegintime);
Param.qryendtime = $ (' #qryEndDate '). Datebox (' GetValue ');
alert (param.qryendtime);

if ($ (' #region ')!= null && $ (' #region '). attr ("checked") = = True) {

}
if ($ (' #county ')!= null && $ (' #county '). attr ("checked") = = True) {
Strstatcond + = ", c.county_name";
$ (' #tt '). DataGrid (' Showcolumn ', ' county_name ');

}else{
$ (' #tt '). DataGrid (' Hidecolumn ', ' county_name ');
}

if ($ (' #area ')!= null && $ (' #area '). attr ("checked") = = True) {
Strstatcond + = ", d.area_name";
$ (' #tt '). DataGrid (' Showcolumn ', ' area_name ');
}else{
$ (' #tt '). DataGrid (' Hidecolumn ', ' area_name ');
}
if ($ (' #org ')!= null && $ (' #org '). attr ("checked") = = True) {
Strstatcond + = ", e.org_name";
$ (' #tt '). DataGrid (' Showcolumn ', ' org_name ');
}else{
$ (' #tt '). DataGrid (' Hidecolumn ', ' org_name ');
}
alert (Strstatcond);
Param.statcond = Strstatcond;
Param.rptname = "Statbusirpt";
Jsbasecall.execute (PARAM,SHOWRESULT2);
}
Show recordset
function ShowResult2 (data) {
var strjson=data["defaultjsonstring"];
var result=eval (' + Strjson + ');
alert (Strjson);
if (result. Key_jscall_result) {
if (result. Key_service_res) {//success
Totalrec=result. Key_total_rec;
var d={"Total":p Ageshowrec,
"Rows": result.defaultalist
};
$ (' #tt '). DataGrid (' LoadData ', d);
}
}
}

For example, in the "Qu County" when there is no data, the table does not show empty columns, but directly to hide this column
