is it possible can default sort in datagrid with itemRender label?

We know already Datagrid default sorting, when we click on header of dategrid then automatically sorting records well. But how can we sort within inline itemreander linkfield label in 开发者_高级运维datagrid. In project default sorting properly work in datagrid but linked field column only not sorting? Is it any way to sort functionality? if u know please refer it.

You need to implement a sortCompareFunction for the column using the inline item renderer.

Check the FLEX API Reference
