Hello,

I am trying to use the FilterExpression using multiple params/placeholders

The following code runs, but the search returls no results
I can get it to work fine with just one parameter

<%@ Page Language="VB" %>

    <form id="form1" runat="server">
    <div>

    <asp:Textbox id="txtCompName" runat="server" />
        Search Company Name<br />
        <br />
        <asp:TextBox ID="txtId" runat="server"/>
        Search ID<br />

        <asp:TextBox ID="txtPostCode" runat="server"/>

    <asp:Button ID="btnMatch" Text="Match" runat="server" />

    <asp:GridView ID="grdCustomers" DataSourceID="srcRitestar"
    runat="server" />

    <asp:SqlDataSource ID="srcRitestar"
    SelectCommand="Select CustomerId,CompanyName,CompanyAddress,ContactName, TelNum,FaxNum,EmailAddress,PostCode FROM Customers"
    FilterExpression="PostCode LIKE '{0}%' OR CompanyName LIKE '{1}%' "
    ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
    runat="server">
    <FilterParameters >
        <asp:ControlParameter Name="PostCode" ControlID="txtPostCode" />

    </FilterParameters>
