Flex - Sending a parameter to a custom ItemRenderer?

Question

What I am trying to accomplish to to get financial data in my Flex Datagrid to be color-coded--green if it\'s positive; red if it\'s negative. This would be fairly straight

Answer 1

You may want to look into ClassFactory from the Flex APIs:

This allows you to set a prototype Object with arbitrary types / values each of which will be passed to the item renderer. From the sample:

var productRenderer:ClassFactory = new ClassFactory(ProductRenderer);
productRenderer.properties = { showProductImage: true };
myList.itemRenderer = productRenderer;

The above code assumed that "ProductRenderer" has a public property called "showProductImage" which will be set with a value of "true."
