ShowhideToggle For Render Method ? - Ssrs 2000

Hi there.



I had been looking around for some info about this.

So far I understand that the showhidetoggle parameter determines which drilldowns are visible or hidden.



I am trying to use the render method, and try to show the drilldowns on my html page.



First question:

How does the showhidetoggle work in the URL or even show an example of how the drilldowns work through showhidetoggle ? In other words, how does the showhidetoggle knows which one to display if I have only one string value ? Maybe there is another way to do this or another way to define this syntax ?



Second question:

How do i determine the number or the string parameter without having to look through html ? is there a way to do this so that I can pass this string to the parameter in the ASMX ?



Thanks for reading this post !
