    [CLOSED] Need ability to search combobox items by lower case or upper case


    In the combobox example below, I can filter down to the customer I am searching but only if what I type in the exact case. How do I make it work regardless of the case?

    <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="SelectCustomerOnlyName.aspx.vb"
        Inherits="EXTTabs.SelectCustomerOnlyName" %>
    <%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
    <script runat="server">
     Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
            Me.Store1.DataSource = New Object() {New Object() {"12345", "ABC Ltd (12345)"}, New Object() {"5444", "XYZ Inc (5444)"}, New Object() {"67677", "Overseas Iron Works (67677)"}, New Object() {"234234", "Software Services(234234)"}, New Object() {"7765756", "Movie Zone(7765756)"}, New Object() {"76866", "Johnson Clips (76866)"}, _
     New Object() {"465464", "Sports House (465464)"}, New Object() {"57655", "Green House (57655)"}}
            btnOkCustomer.Disabled = True
        End Sub

    Please add the case insensitive flag for the regular expression.
    new RegExp(v, "i");
