DropDownList not allowing SelectedIndex = -1

[MrSmoofy]

Ok I'll start out with I found:

http://support.microsoft.com/kb/327244/
BUG: ComboBox Does Not Clear When You Set SelectedIndex to -1

Ok so in HTML you can have:

<select id="MyList">
<option value="1">1
<option value="2">2
<option value="3">3
</select>

And in javascript you can set MyList.selectedIndex = -1 which will display
the dropdown with nothing selected.

I'm using .NET 1.1 and this doesn't work? WHY? Why has there been no fix
for this that I can find. The ListBox control allows the SelectedIndex = -1
and shows the list with nothing selected but the Dropdownlist control reverts
to SelectedIndex = 0 when you set it to -1 and always shows the first item
selected.

Yes I know I could add a blank item to the list but that's not the point.
Microsoft Obviously knows there a bug but hasn't fixed it. Even the work
arounds do not work.

Anyone have any comments or solutions about this.

there is no html solution for this as the selectedItem is not exposed.
client script is required, probably why asp.net does not support it.

<asp:listbox id=listBox1 runat=server>
<asp:ListItem>1</asp:ListItem>
<asp:ListItem>2</asp:ListItem>
<asp:ListItem>3</asp:ListItem>
</asp:listbox>
<script>
document.getElementById('<%=listBox1.ClientID%>'). selectedIndex=<%=listBox1.selectedIndex%>;
</script>

Your wrong sorry to tell you.

For a list box SelectedIndex = -1 works fine as expected but for a
dropdownlist it doesn't however it should and according to the bug report
from Microsoft they knew it was a problem in .NET 1.0 and had a workaround
but in 1.1 the workaround doesn't work and the bug is still there.
