Hi All,
Am working on Telerik control with two radcomboboxes and a textbox. Selection on one combobox will fill another combobox and selection of second combobox will fill textbox. The code works fine but on selection of value in comboboxes, the page gets loaded. I want to accomplish the same task without page load.Pls help...
This is my clientside code:

<head id="Head1" runat="server">
    <style type="text/css">
        .#formComboFill {
            width: 500px;
    <form id="formComboFill" runat="server">
        <table class="style1">
                    <asp:Label ID="lblName" runat="server" Text="StoreName"> </td>
    <telerik:RadScriptManager ID="RadScriptManager1"  runat="server" EnableScriptCombine="true"> 
    <telerik:RadCodeBlock ID="RadCodeBlock2"   runat="server"> 
           <script type="text/javascript">
               function LoadAddress(combo, eventarqs) {
                   var combo2 = $find("<%=cboSupplier.ClientID %>");
                   var name = combo2.get_value();
                   formComboFill.action = "Combo.aspx?action=loadAddrs&name=" + name;
            <telerik:RadCodeBlock ID="RadCodeBlock1"  runat="server"> 
           <script type="text/javascript">
               function LoadcboSupplier(combo, eventarqs) {
                   var combo1 = $find("<%=cbocheck.ClientID %>");
                   var id = combo1.get_value();
                    formComboFill.action = "Combo.aspx?action=load&id=" + id;
              <telerik:RadComboBox   runat="server" ID="cboName" Filter="Contains" MarkFirstMatch="True" 
 EnableLoadOnDemand="True"  AutoPostBack="false"  önClientBlur="fnalert()" DataTextField="cStr_Name" DataValueField="iStr_id"  DataSourceID="SqlDataSource1"  >
                    <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
                        ConnectionString="<%$ ConnectionStrings:KMCH_InventoryConnectionString %>" 
                        SelectCommand="SELECT [iStr_id], [cStr_Name] FROM [Mast_Store]">
                    <asp:Label ID="lblSuplliers" runat="server" Text="Supplier Names">
               <telerik:RadComboBox   runat="server" ID="cboSupplier" Filter="Contains" MarkFirstMatch="True" OnClientSelectedIndexChanged= "LoadAddress"           
 EnableLoadOnDemand="True" ></td>
                <asp:Label ID="lblAddress" runat="server" Text="">
            <asp:TextBox ID="txtaddrs" Columns="10" Rows="10" runat="server" 
                    TextMode="MultiLine" Width="163px" Height="200px">
