my aspx

XML

<asp:UpdatePanel ID="up" runat="server"><contenttemplate>
     <asp:HiddenField ID="hfCustomerId" runat="server" />
<asp:Label ID="lblEmpCodeSrch" runat="server" Text="EmpCode" CssClass="label">   
 
  <asp:TextBox ID="txtSearch" runat="server" Width="815px" ToolTip="Enter Employeecode" 
            ontextchanged="txtSearch_TextChanged">
     <asp:Button ID="bttnSearch" runat="server" CssClass="submit" Height="23px" Text="Search" onclick="bttnSearch_Click" />
 </contenttemplate>

May be you can try the code given below:

$("#txtSearch").live("blur", function (event) {
var autocomplete = $(this).data("autocomplete");
var matcher = new RegExp("^" + $.ui.autocomplete.escapeRegex($(this).val()) + "$", "i");
var myInput = $(this);
autocomplete.widget().children(".ui-menu-item").each(function () {
//Check if each autocomplete item is a case-insensitive match on the input
var item = $(this).data("item.autocomplete");
if (matcher.test(item.label || item.value || item)) {
//There was a match, lets stop checking
autocomplete.selectedItem = item;
return;
}
});
//if there was a match trigger the select event on that match
//I would recommend matching the label to the input in the select event
if (autocomplete.selectedItem) {
autocomplete._trigger("select", event, {
item: autocomplete.selectedItem

});
//Do something here

//there was no match, clear the input
} else {
$(this).val('');
selectedManagerId = 0;
}
});
