    [CLOSED] Delay firing of Direct Method ...

    I have a gridpanel with a checkbox column.
    When the checkbox is checked/unchecked, it fires an ajax call to update data using a handler...
    The problem is that if a user runs down the list really quick, it fires a bunch of times...

    The return of the direct method causes the entire grid to refresh...

    Any good ideas? Any simple way?

    I just want to be able to cancel a call, or not reload the grid if there is a pending call...

    Does the "Delay" effectively cancel any previous calls? Or do they Q up and after a 5 second delay are you left with 10 calls that are going to fire?

    This fires after each "check"
                    type: "POST",
                    url: "/Handler/BalanceSheetGridUpdateHandler.ashx",
                    data: JSON.stringify(arrChanges),
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    error: function (msg) {
                        scripts.messageTop('Error', msg.responseText, 'danger');
                    success: function (response) {
                        App.ContentPlaceHolder1_store.load();  <--this then reloads the entire grid...
    The store is configured as such:

                        <ext:Store ID="store" runat="server" GroupField="GroupTitle">
                                <ext:AjaxProxy Json="true" Url="/Handler/PerformanceMetricsGridHandler.ashx">
                                    <ActionMethods Read="POST" />
                                        <ext:JsonReader Root="records" />
                                <ext:StoreParameter Name="metricType" Value="#{hidMetricType}.getValue()" Mode="Raw" />
                                <ext:StoreParameter Name="docId" Value="#{hidDocumentId}.getValue()" Mode="Raw" />
                                 <Refresh Handler="footnoteCount=0;#{storeFootnotes}.load(); " />
                                     <Load Handler="footnoteCount=0;#{storeFootnotes}.load();" />

    Hi @rthiney,

    It might be enough to use the Buffer setting for a listener which you use listen to check/uncheck events.
