Take note: The answer marked as the solution addresses the issues presented in the Title. However, I was able to resolve my underlying issue with type ahead dropdowns by switching to IE8.
I am looking to trigger a postback ("this.form.submit()") when a new selection is CLICKED in a dropdown list, but only if the click actually changed the selection.
The OnChange event will not suffice as I do not want to trigger a postback when the selection is changed using the keyboard in a type ahead dropdown list.
One possible solution might be to use OnChange and then verify if the change was due to a mouse click.
If we can explore both options, I can determine which one works best?
Thank you for your assistance!!!!!
EDIT: More details:
Setting AutoPostback to true will not be effective (do not want to post back when selection is changed using keyboard).
Using onBlur = doPostBack; was attempted, but the outcome was suboptimal. User had to click off the dropdown list after making a selection with the mouse.
To simplify, I want to trigger a postback when both the OnChange and OnClick events occur simultaneously.
