ASP.NET Dropdownlist selectedindexchanged event not firing on up / down arrow

I have a server dropdownlist in an Ajax updatepanel. When I use the mouse to click on an item it fires the postback but when I click the up/down arrow to change entries, this is not firing. What could be reason?

Try setting the 'AutoPostBack' property of the DropDownList control to 'true'. 

<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="true">
</asp:DropDownList>

See ListControl.AutoPostBack Property on MSDN for more info

Gets or sets a value indicating whether a postback to the server automatically occurs when the user changes the list selection.

If you want it to work with the arrow keys, you should use the client side event, onKeyDown.

Try this:

<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" 
OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" onKeyUp="this.blur();">

With onKeyUp="this.blur();" the control will lose focus when a key is unpressed, and that will trigger the onChange event.

I think you have to leave the control if you are using the keyboard in order to fire the event.
