Sir I'm using UniGUI Complete Professional V1.90.0.1560 in RAD C++ Builder 10.4 Update 2. I'm getting an Ajax error when trying to assign a new title to a stream of a UniChart. I have the following procedure: void __fastcall TMainForm::SetNewTitle(TUniChart *ThisChart, int StreamNo) { UnicodeString NewTitle; NewTitle = "New Title"; if (StreamNo==0) ThisChart->JSInterface->JSCall((UnicodeString)L"chart.series[0].setTitle",ARRAYOFCONST((NewTitle))); if (StreamNo==1) ThisChart->JSInterface->JSCall((UnicodeString)L"chart.series[1].setTitle",ARRAYOFCONST((NewTitle))); if (StreamNo==2) ThisChart->JSInterface->JSCall((UnicodeString)L"chart.series[2].setTitle",ARRAYOFCONST((NewTitle))); } As long as the UniChart has 3 UniLineSeries, everything works fine when I call SetNewTitle(UniChart,0); SetNewTitle(UniChart,1); SetNewTitle(UniChart,2); But as soon as I use 3 UniBarSeries, UniAreaSeries or any other series on the UniChart, then calling SetNewTitle for all 3 series gives an Ajax error: "Cannot read properties of undefined (reading 'SetTitle')" The easiest fix would be to allow us to set the Title property for each Series in the SeriesList: UniChart->SeriesList->Series[0]->Title = "New Title"; UniChart->SeriesList->Series[1]->Title = "New Title"; UniChart->SeriesList->Series[2]->Title = "New Title"; Then we don't even have to use the JSCall which is not working for UniBarSeries, UniAreaSeries and other series in C++Builder. By the way, I have to tell you that the uniGUI framework is most amazing. I only have the greatest respect for your work, you are a genius!! If only we could fix this bug then I will be a vey happy customer…

thank you

Hi, How can perform calculations (or checks) only on the client side? I mean field c=field a+field b, but directly in the client store or on the values present directly in the editors (DB) that are in the form. But all on client side, without making ajax calls to the server? (Server dataset must be updated on post record) Thank you
