1st dropdown box is main category
when 1st dropdown box is clicked, 2nd dropdown box list the sub category
when 2nd dropdown box is clicked, the datagrib show the data according it
2nd dropdown box
it works to some extent by "human clicks".
however, when i click 1st dropdown box, 2nd dropdown changed but datagrib
not changed.
If i click 1st dropdown, so that 2nd dropdown will be triggered to change
"by code".
How can i do? Then datagrib can be changed!
Thanks a lot.

Hi Tony,
It is as simple as you did with 2 dropdownlists.
You must have written a code in "dropdownlist1_ selectedindexch anged" 2
change 2nd dropdownlist. Like that you can call the datagrid bind
function in "dropdownlist2_ selectedindexch anged".

Hi Mansi
Thanks for your reply
i did not write any code on the dropdownlist. i just bind them to data
source objects.
The datagrid can be refreshed by "MANUAL click" on 2nd dropdownlist
my problem is
when i click 1st dropdownlist, then it fires to 2nd dropdownlist, but the
datagrid is not updated
what should i do? grateful for any hints?

Hi,
As per my knowledge, if you want to refresh the datagrid as per some
value(like dropdownlist in your case), you have to write some condition
or code for that. And you have to bind the datagrid by datasource in
your .cs or .vb file.
It would be gr8 if you can send me your code, where you have bind the
lists and grid.

Mansi Shah.

Hi,
Consider a window with 2 linked dropdownboxes, dynamically
fed from a dbase.
One technique to implement this would be to use an onchange
event on the first box, then have the script call itself again,
this time with a GET variable, calling the db for a 2nd time to
populate the 2nd dropdownbox. (using PHP)
