recommend using an itemEditor since you are modifying value and want to store it.
Also, would advice you to store the value of the selected item on the original array. You can still achieve this functionality using itemRenderer.. but can be a tricky functionality. Search for itemEditor on Flex help and read about it. read some details on modifying itemRenderers out here. http://blogs.adobe.com/aharui/2007/03/thinking_about_item_renderers_1.html I am curious, how others would treat this... would like to see a sample working code from people. regards, Varun Shetty On Tue, Oct 7, 2008 at 3:25 PM, malavika <[EMAIL PROTECTED]> wrote: > > Hi Venkat, > Thanks for the reply.You didnot get my problem....actually... i > have a datagrid for which i have been adding ComboBox using > ItemRenderer.The dataprovider for the ComboBox is static one(as you > can see in the above code).
