I want to design the same grid as shown above..but I am unable to get the exact design..I used a datagrid but unable to customise it accordingly..
Try following the below steps
1. extend AdvancedDataGridColumnGroup class to add the radiobuttons and other components in header. U can refer below link to see how column grouping works
2. Use verticalSeparatorSkin property to customize the vertical column seperator to hide the vertical lines seperating the columns.
