the item param is row data, what is in that row of the array collection and the column is that column in the grid.
basically what happens in this particular labelFunction is that it looks at a specific field in the array collection and determine its value, then it sets a string to be returned and displayed in that column for that row. You could return a number, boolean etc just by changing the return type of the function. make sense? On 2/13/07, jryano001 <[EMAIL PROTECTED]> wrote:
Brilliant thanks for all your help. Can you do one more thing and explain exactly what the line below is doing please? checkData(item:Object,column:Object):String Is it converting the parsed XML data in my ArrayCollection to a String before searching the converted string for the number 2?
