[flexcoders] Re: Datagrid itemrenderer for adding multiple linkbuttons in same gridcolumn

[aramsdell2000]

OK, that's the problem. I don't know how to add multiple link buttons through 
action script. And here goes my feeble attempt at explaining what I did so that 
it makes sense:

This is how I am now populating the column with multiple hyperlinks, using the 
itemrenderer approach from Alex's Flex Closet "HTML in an Item Renderer" on 
this website:
http://blogs.adobe.com/aharui/item_renderers/

var params:Array = (data[column.dataField]).split(", ");
var urls:String = "";
for (var i:Number=0; i < params.length; i++)
{ 
    ... 
    urls += "<a href='http://webaddress?charname="; 
                + params[i]
                + "&amp;someid=" 
                + station 
                + "&amp;anotherid=" 
                + org 
                + "' target='_blank'>" + params[i] + "</a>, ";
}
...
cdataTag = urls;
.....
htmlText = cdataTag;

but only a right click works to open a new window. I would like it to work with 
just clicking on the text like a normal HTML href.

So what I wanted to do was have each string be a link button (except i don't 
really like the fact that it looks like a button). I have been experimenting 
with using a single linkbutton in a datagridcolumn for something similar:

else if (column.dataField == "details"){
var linkItemRendererFactory:ClassFactory = new ClassFactory(LinkButton);

var someid:String = data["someid"];
var anotherid:String = data["anotherid"];

var queryExpr:String = "&SomeParameterId=" + someid           + 
"&AnotherParameterId=" + anotherid + "restofurl";
//this line isn't quite working either but I hope you get the idea..
//linkItemRendererFactory.properties = 
{label:data[column.dataField],click:"callGetDetailsWebService(" + queryExpr + 
");"};

linkItemRendererFactory.properties = {label:data[column.dataField]};
column.itemRenderer = linkItemRendererFactory;

I am not sure how to expand the above code to add multiple buttons. Instead of 
using an inline? renderer, do I have to make a new link button class and extend 
it or can I somehow write it into the custom CustomDataGridItemRenderer class I 
have now  that extends DataGridItemRenderer.

Hopefully that makes sense!

Thanks!
Amy
