how to change session value every time

[vrsf]

I have a splitter.In the left pane of the splitter I have a grid and in the right pane I have tabs.I put selected record in the grid ID value in the session like \[code\]sessionStorage.setItem("ID",id)\[/code\]. passing this id value to the right side tabs and displaying tab content depending upon ID.For the first selected record,it is displaying with that particular id value,If I select different record in the grid then also the Id value is not passing to the tabs and displaying the content with first selected record id.
