OnItemUpdate x OnChangingValues

IngridBrandao

Dear All,

I'm confused.

I need to know if an element has a new value. After this verification, I need to change its CSS class according to the new value.

How can I work with "OnItemUpdate" and "OnChangingValues" methods at the same time?

Is this possible?

Hi,

you can take a look to the sources of the StockListDemo to see how we handle the highlight color (green if the last_price is greater than the previous one, red otherwise)
Search for the following code lines:
[SYNTAX=JS]updateInfo.addField("#trend_color",redColor,true);

[...]

var backH = itemUpdate.getServerValue("#trend_color");
itemUpdate.setRowAttribute(backH,backC,"backgroundColor");
[/SYNTAX]

you can find the sources of the demo for the Lightstreamer version you're using here: http://www.lightstreamer.com/distros/Lightstreamer_Moderato_4_0_3_Duomo_20120406/Lightstreamer/pages/demos/StockListDemo

If you want to check out the same demo developed with the brand new version of Lightstreamer, you can see it here: http://www.lightstreamer.com/demo/StockListDemo/ note that the code is quite different; you should be able to recognize the important bits anyway

let me know if you have any doubt.
