Re: Why can't I set the listbox selectedIndex to -1?

this can only be done in javascript. in html if you render a select with no option set as selected, it defaults to the first. in javascript you can set the selectedIndex to -1 which will unselect.

you can subclass the listbox, and have it generate the required javascript.

I have a simple webform that has a listbox that I bind to a dataview

wanted to have no default value selected. So on the Page_Load event,
I set the selectedIndex to -1. However, when I run the page, the
default value is still 0, which forces the first item to be
automatically selected. I tried a bunch of things. I tried setting
it to 0, then -1. I tried to call ClearSelection() then set it to -1,
but no avail. This is a listbox, for crying out loud! This ought to
be simple, but is not.

Need help.
