Hi Guys,
Need your help on the below situation.
I have a page which is showing "List of Cases" for my organisation.I have added a filter 'Status' so that it can refine the case list based on requirement.Status options are 'New' and 'Resolved' Cases and after choosing any one of the option if I hit the search button it will show the list of cases based on the status.If no option is selected by default it will show the all cases in the list.
Now the requirement is if I apply case filter status as 'new' and if it retuns 4 cases, after clciking any one of that case it should redirect to the case detail page and after clicking the 'back to cases' command link in case detail page it should redirect back to refined serach result (it should show all that 4 cases in the list not all the cases) .I am giving my code here .Please help .thanks!!!
