I've been trying to explain to someone why having a large itemed dropdownlist is bad - performance issues. They are binding around 2500 items to that dropdownlist and IE takes around 25-35 seconds before it makes the page usable.
Other browsers however takes a maximum of 5 seconds... which is unfortunate since they want to use IE as their main browser (and I do too!)
Now, I cannot disable viewstate here because they need a postback to occur when the item in the dropdownlist changes.
What options do I have here? They cannot filter the list anymore to reduce the items - the list is ALREADY filtered.
How can I speed up the rendering of the dropdownlist for IE to render the page quickly compared to the other browsers?
