In the canvas i have a chart component.so when i select the link data on the datagrid the focus should be in the chart component in the canvas.

You can attach an event listener to listen for a click on the datagrid and then fire off the setFocus method on the chart to set the focus on the chart.

dataGrid.addEventListener(MouseEvent.CLICK, function():void { chart.setFocus() });
