Is it possible with the standard asp: dropdownlist to have the list expand up rather than down, or do I need to create a custom control?
Until now, I know that the standard drop-down list expands down if there is enough space for this, otherwise it will expand up
So the answer is: you need a custom control :-)
You will need a custom control. The ASP.Net drop-down list is just a wrapper for the main HTML select list.
If you list some details about what / why you need this functionality, we can provide additional suggestions.
