auto complete textbox using jquery UI in vb.net
I am using two autocomplete extenders in my form using jQuery. I want to pass the value of one autocomplete extender to another autocomplete extender. Please let me know how can I pass value using jQuery.
My VB.net page :-
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="VB.aspx.vb" Inherits="VB" %>

<script src="jquery/jquery-1.4.1.min.js" type="text/javascript"></script>
<script src="jquery/jquery.autocomplete.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#txtSearch").autocomplete('Search_Scheme.ashx');
});
$(document).ready(function() {
$("#txtProperty").autocomplete('Search_Property.ashx');
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<table cellspacing="0" cellpadding="0" align="center" border="0" style="text-align: left" width="95%">

<td align="center" bgColor="#ffffff" style="width: 50%;">
<asp:TextBox ID="txtSearch" runat="server"></asp:TextBox>
</td>
<td align="center" bgColor="#ffffff" style="width: 50%;">
<asp:TextBox ID="txtProperty" runat="server"></asp:TextBox>
</td>
</tr>
</table>
</div>
</form>
</body>

You want to set the extraParam option, as in:
$("#txtProperty").autocomplete('Search_Property.ashx', { extraParams: { scheme_id: 2271 } });
see: http://docs.jquery.com/Plugins/Autocomplete/autocomplete#url_or_dataoptions
If you need the values to be cascading, you'll have to set a select handler on the parent to store the selected value in a closure or somewhere on the page. (unless the value is what the user typed/selected, in which case you can just grab it from there.) U
