Filter dropdownlist selection values on the client side

[Bob]

I wonder if it is possible to filter the selections of a drop down list on the client side. I need to do this dynamically since the DDL is used in a grid.

Basically, the idea is to remove hide items in the drop down that have been selected in the other rows of the grid. There is a small data set here, so I don't want to do a read each time.

I don't see any event that fires prior to dropdown either.

So, what event fires prior to dropdown? Also, can I prevent dropdown if some condition is meet?

thanks...

Hello Bob,

 
I will suggest you check this jsFiddle demo, which shows how to filter a dropdownlist on some condition.

Could you please clarify what "So, what event fires prior to dropdown?" and "can I prevent dropdown if some condition is meet?" means?

You can check the supported events of the DropDownList here.
