Can't access dataset's

Hi, I need some help with a TDBChart.
I have a FMX application with a main form. Also I have a TDataModule where put a TFDConnection and a couple of TFDQuery.
The main form is including the TDataModule. Then I added a TDBChart on main form and a Series1.
When I edit the TDBChart to specify a Dataset for the Series1 it didn't show the query's that I have on the data module. I have selected Dataset option on the first combo box on the Data Source page, however the second Dataset combo box remains empty.
I'm working with C++Builder 10.4.2 recently launched and with 2020.31 version of TeeChartVCLFMXStandard.
What could be wrong?
Best regards,
Patricio Cerda

Hello,
I've tried it in a new simple project and it seems to work without problems:
- FMXFDQuery.png (46.72 KiB) Viewed 52770 times
Have you tried it in a new simple project?
If you still find problems with it, please send us a simple example project we can run as-is to reproduce the problem here?
Thanks in advance.

Hello,
Thanks Yeray for your help.
I just tried with a new project replicating the same conditions of my project and the problem comes again.
The difference with your example is that you are putting the TFD components on the same main unit, instead of put them on a separate Data Module as on my case.
On my simple test project I added a unit2 (the datamodule with TFD components) and then I included it to the unit1 (main form) so now I have an #include "Unit2.h" sentence in the unit1, however I can't see the query component on the TDBChart.
I'm attaching my simple testing new project for your revision, and a couple of screenshots.
Best regards,

Hello,
I'm finding problems with it and I'll do more tests.
In the meanwhile, have you tried to set the series' datasource at runtime? Ie (delphi):
Code: Select all
Series1.DataSource:=DataModule1.FDQuery1;
Series1.YValues.ValueSource:='Salary';
Series1.XLabelsSource:='LastName';

Hello,
Sorry, I've just realized I wrote just FDQuery1 where it should be DataModule1.FDQuery1. I've edited the reply above.

Hi
just to note that I have an identical issue with setting dataset connectivity in design mode, using the latest binary install version of TeeChart FMX with Delphi 10.3.
Everything works fine if I define the connections at runtime in my code.

Hi,
I just upgraded to RAD Studio 11.1 and TeeChart Standard is still failing in this matter, it still prevents setting the graph at design time.
It is important for me that you could check that please.
Best regards,
