UX DATA SERIES, where data is being populated from List Control

[Ken Tjia]

I am familiar with populating a data series in UX with data from Sql or dbf.

However, my need to have "data Series" populated from an existing List Control on a typical mobile device Wrapped with Phonegap.

I know there is option to use Javascript as source of data.

Can someone share a sample of getting the latitude/longitude values out of a simple list control
where it has these fields in it :

city/latitude/longitude

Why ?

I found that perform an ajax call back to populate my array while running from a mobile device is not too reliable/slow
since such data already residence within a mobile device, i would like to use them to plot multiple markers on a map.

appreciate your assistance.

Thanks

Hi Ken search for this video series

List Control - Methods - Populating List, Moving Data from One List to Another - Moving Rows Up and Down
They are in version 12.

Selwyn includes the data. In the example he populates with static data.

Here is a code snippet

function populateList() {
var lObj = {dialog.object}.getControl('LISTSOURCE');
var _d = [
{Firstname: 'John', Lastname: 'Smith',City: 'Boston'},
{Firstname: 'Freeda',Lastname: 'Frankel',City: 'Capetown'},
{Firstname: 'Francis',Lastname: 'Higgins',City: 'Durban'},
{Firstname: 'Ken',Lastname: 'King',City: 'London'},
{Firstname: 'Don',Lastname: 'Draper',City: 'Moscow'},
{Firstname: 'Frank',Lastname: 'Maloney',City: 'Paris'},
{Firstname: 'Nancy',Lastname: 'Parker',City: 'Washington'}
];
lObj.appendRows(_d);
//set focus to first row
lObj.setValue(0);
}

function insertData(listId,_d) {
var lObj = {dialog.object}.getControl(listId);
var flagAppend = false;
var row = 0;
//if there is no data in the list, or the last record is selected, do an append
if(lObj._rData.length == 0) {
flagAppend = true;
} else {
var row = [].concat(lObj.selection);
row.sort();
//get last value in array
row = row.pop();
row++;
if(row >= lObj._rData.length) flagAppend = true;
}
if(flagAppend) {
lObj.appendRows(_d);
} else {
lObj.insertRows(row,_d);
}
var target = row + (_d.length -1);
lObj.setValue(target);
}

More good stuff from Selwyn is available here. http://www.ajaxvideotutorials.com/V1...ux_rawdata.swf
Raw data has Html stripped out. I watched another video recently where he shows this in use.

Thanks Michael for your reply/post

I have since received assistant from Mr. Slewyn

Quote :

if you have an existing List control then you can easily populate the data series from data in the list control.

just set the data series data source to 'Javascript'

to get the data in the List you can use this

var _d = {dialog.object}.getControl('listcontrolname')._data;

_d will be an array with all of the data in the List.



All make sense and I have also added the

SUBSERIES NAMES : to match the field name in my list control.

unfortunately when I click preview within the DATA SERIES builder
i only see blank ...

I know it is closer .... Pretty sure the array is being generated.

Hi Ken,

I have a similar setup. Were you able to get the list data into the data series array?

Thanks,
