OnAjaxEvent receive binary files sent by the client？ Thank you！

Hi, Q1, I have a problem on ajax events that I can't find any source to resolve the problem. I use DevExtreme grid/pivotGrid (for column filter checkbox with data...) in uniHTMLFrame, with ajaxRequest, I need to load data in JSON format. I can see the XHR data is sent to browser correctly from chromeDeveloperTools, however when I look at result from console, i see only result = "true" and no data displayed in grid. if I use JSON String directly, no problem... I tried many way to handle the respone but i couldn't handle... Q2, if I use uniHTMLFrame in a Modal Form, devexpress filter column popup appears on mainForm, popup goes out from htmlFrame, I couldn't find any solution without putting uniHTMLFrame in to main form. What am I doing wrong, thanks. <div class="demo-container"> <div id="gridContainer"></div> </div> <script> $(function(){ var GetCustomers = function(e) { var deferred = $.Deferred(); result=ajaxRequest(MainForm.UniHTMLFrame1,e,[]); <!-- result=[{"ID":1,"CompanyName":"Premier Buy"}] THIS IS OK--> console.log(result); deferred.resolve(result); return deferred.promise(); } $("#gridContainer").dxDataGrid({ dataSource: GetCustomers('load'), columns: ["ID","CompanyName"] }).dxDataGrid("instance"); }); </script> procedure TMainForm.UniHTMLFrame1AjaxEvent(Sender: TComponent; EventName: string; Params: TUniStrings); var s:string; begin if EventName = 'load' then begin s:='['+ '{"ID":1,"CompanyName":"Premier Buy"},'+ '{"ID":2,"CompanyName":"ElectrixMax"},'+ '{"ID":3,"CompanyName":"Video Emporium"}+ ']'; //unisession.JSONDirect(s); //unisession.Response := s; unisession.SendResponse(s,true); end; end; Platform: Delphi Tokyo, uniGui 1.0.0.1424 (licensed)

Hi, I cannot figure out how to fire the OnAjaxEvent from JS-code within the loaded page. ajaxRequest can be called with "parent.ajaxRequest", but I cannot determine the first parameter "sender" I tried: - parent.ajaxRequest(this, "ClickEvent", [ "param0=a", "param1=b" ]); - parent.ajaxRequest(O3C, "ClickEvent", [ "param0=a", "param1=b" ]); // where "O3C" is the JS-name of the UniURLFrame (added via code on startup) - tried to get a reference to the UniURLFrame-control with: - var x = parent.getElementById("O3C"); // x is null - var x = parent.getElementById("O3C_id"); // x is null nothing works. Can anybody help please? best regards steve

My team is really looking forward to get the commercial version of Unigui. Thank you very much for your help.
