I recently found that dropdownlist events are not shown in properties window.
I was disappointed.
I already hate asp.net designer in visual studio. its slow and full with ugly things like this.
please help me. I need to generate events automatically not to write it by hand.

If you want to create
OnSelectedIndexChangedEvent you can double click yourDropDownListin design view.if not try writing this :
and then press tab 2 times. so it will create event handler for you. then you need to copy your handler name and paste it in your control markup.
