change the color of fields and display images(up,down)

[hungn]

thanks Mone.
I could add images(up,down). because i dont remember some of the code lines :
lsTable.setPushedHtmlEnabled(true) so images didnt appear(url is false).
thanks you for detail info.

I dont understand the code fully.

For the images to work properly, does the field need to be pushed from the server?

[Mone]

no, it is not necessary that the image field is pushed by the server:

all you need to do is to prepare a cell for your extra field (ie a cell with a field name/index that differs from fields sent by the server; note the # in the name of the field, it can be useful if you create you table "fetching" the schema from the html fields, see table constructors for details, eg OverwriteTable)

<span source="lightstreamer" table="yourTable" item="yourItem" field="#image">-</span>

set your table to push html values through the setPushedHtmlEnabled method (please read carefully the documentation of such method)

yourTable.setPushedHtmlEnabled(true);

and finally put the html for your image in the table

yourTable.onItemUpdate = function(pos,obj,name) {<br /> //some code<br /> obj.addField("#image","<img src='yourimage.gif' />");<br /> //more code<br /> }<br />

this is just a basic example, you could obviously use other approaches to show your image
