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

[Mone]

What you've done is to add a cell to your table, but any cell you add should have a correspondant field.

field="16"
In the case of the HTML demo the field number 16 is a field added in a callback and contains the html of the img (eg: <img src="arrow.gif" />).

if (updateInfo.isValueChanged(3)) {<br /> var val = updateInfo.getNewValue(3);<br /> if (val.indexOf("-") > -1) {<br /> updateInfo.addField(16,imgDown);<br /> } else {<br /> updateInfo.addField(16,imgUp);<br /> }<br /> }


item="'+i+'"
Moreover in that demo the html of the cells is made with a for statement so the i is used to set at any cycle a different item number. The ASP.NET demo does not have such logic.



I advice you to read the "Web Client Dev.pdf" and "Web Client Tutorial.pdf" files located in the distribution under LS_HOME/DOCS-SDKs/sdk_client_web/doc/ and this post: http://www.lightstreamer.com/vb/showthread.php?t=49

Hope that helps.
