Hi Tino
That is possible.
You need to use something like this:
js code include on the page
Code:
<script language="javascript" type="text/javascript">
function State_OnSelect(sender, item){
__doPostBack($(<%=UpdateButton.ClientID%>).id,'');
}
</script>
this is the control
Code:
<cc1:AdvancedAutoSuggestExtender TargetControlID="StateTextBox" ServiceUrl="~/Suggestions.asmx/StateSuggest"
OnClientItemSelected="State_OnSelect" ID="StateAASE" runat="server" />
<asp:ImageButton ImageUrl="http://www.convincingmail.com/i/bullet_go.gif" ID="UpdateButton" runat="server" />
I never tested this code but it should work fine ;)
Thanks
Mikhail
