accessing keys in hash table ...........

[gurmeet07]

hi guys

if i m navigating among the records saved in hash table...........i.e. first record , previous record , next record and last record as navigating buttons can be there on a form..................
if i want to access the first key , previous key , next key and last key from the hash table how to access that ??????

and then accordingly record will be displayed....................

i have tried like : ICollection key = (ICollection)ht.Keys;
it's not working

is there any way so that i can store all the keys in an array or array list so that i can acess it thru indexes.............then my work will be done........as i want the key which is id of the employees to be diplayed in the textbox

but i dnt know how to do that????


thnx in advance
