Hi kengkit,

About pass multiple parameters to webmethod or webservice with AutoComplete extender, you could use ContextKey property.

1. You could use UseContextKey ="true".

2. You could set the value of the contextkey in JS.

Sample Code:  

<asp:TextBox ID="txtContactsSearch" runat="server" onkeyup = "SetContextKey()"></asp:TextBox>
<cc1:AutoCompleteExtender ServiceMethod="SearchCustomers"
    MinimumPrefixLength="2"
    CompletionInterval="100" EnableCaching="false" CompletionSetCount="10" 
    TargetControlID="txtContactsSearch" UseContextKey = "true"
    ID="AutoCompleteExtender1" runat="server" FirstRowSelected = "false">
</cc1:AutoCompleteExtender>

For more details, please refer to these tutorials:
