runtime error: 'Ext.net.DirectMethods' is null or not an object

[Holly]

I upgrade my project from ext.net version 1.0 to version 2.3. my page DocumentListpage.aspx has master page. ext:ResourceManager tag is in master page. DirectMethods is defined in DocumentListpage.aspx. when I run the DocumentListpage and click 'Search' button. it suppose to run DirectMethods, but I got Javascript runtime error: 'Ext.net.DirectMethods' is null or not an object.
Here are partial code in masterpage:

<form id="form1" runat="server">
    <ext:ResourceManager ID="ResourceManager1" runat="server" />
     <Listeners>
            <DocumentReady Handler="fristLoad=true;Ext.getDoc().on('keydown', function (e) {if (e.getKey() == e.ENTER) {DoSearch(#{cmbDocTypes}.getValue());}});" />             
        </Listeners>
    <asp:ContentPlaceHolder ID="ContentPlaceHolder2" runat="server">
    </asp:ContentPlaceHolder>

Here are DocumentListpage server side code for search:

[DirectMethod]
        public void SearchAction(string searchCondition, int docTypeID)
        {
            try
            {
                List<DocumentKeywordItem> seachValues = CooliteUIHelper.ParseSearchFormPanelSubmitValues(docTypeID, searchCondition);

                 
                this.tabMain.Loader.Url = "DocGridList.aspx";

                this.tabMain.Loader.Params.Clear();

                this.tabMain.Loader.Params.Add(new Ext.Net.Parameter("doctypeid", docTypeID.ToString()));
                this.tabMain.Loader.Params.Add(new Ext.Net.Parameter("isquery", "1"));

                foreach (DocumentKeywordItem seachValue in seachValues)
                {
                    if (string.IsNullOrEmpty(seachValue.KeywordValue))
                        continue;

                    this.tabMain.Loader.Params.Add(new Ext.Net.Parameter(seachValue.KeywordName, seachValue.KeywordValue));
                }

                this.tabMain.LoadContent();
                 
            }
            catch (Exception ex)
            {
                string strmsg = "Error in DocumentListPage::SearchAction: " + ex.Message;
                ErrorLog.WriteErrorLog(strmsg, Application["ErrorFile"].ToString());
            }

        }

here are patial code in DocumentListPage client side code:

function DoSearch(fpanel,id) {  
             var formval = App['ff'+id].getForm().getValues(true); 
              SearchForm(formval,id);
        }

        function SearchForm(formValues, doctypeid) {
            Ext.net.DirectMethods.SearchAction(Ext.encode(formValues).toString(), doctypeid, {
                success: function(result) {
                },
                failure: function(msg) {
                    Ext.Msg.alert('Failure', msg);
                },
                eventMask: {
                    showMask: true
                }
            });
        }

<ext:FormPanel ID="Tab1" Frame="true" runat="server" Title="Keywords" Layout="card"
                                ActiveIndex="0" ButtonAlign="Right" AutoHeight="true">

                                    <ext:Panel ID="pnlNull" runat="server" Html="No document type" Border="false" Header="false" />
                                </Items>

                                    <ext:Button ID="Button1" runat="server" Text="Search" >
                                        <Listeners>
                                            <Click Handler="DoSearch(#{ff1},#{cmbDocTypes}.getValue());" />
                                        </Listeners>
                                    </ext:Button>
                                    <ext:Button ID="Button2" runat="server" Text="Reset">
                                        <Listeners>
                                            <Click Handler="ResetSearchForm(#{cmbDocTypes}.getValue());" />
                                        </Listeners>
                                    </ext:Button>
                                </Buttons>
                            </ext:FormPanel>
