Steema Central

Now we start to use new version of TeeChart component (TeeChart 2009 for .NET) and have a problem when it used in ActiveReport.
Problem:
TeeChart control is blank when it used as a CustomControl in DataDynamics ActiveReport. Anything displayed in place where chart should be.
Previously we used old TeeChart for .NET 1 and it works well.
Maybe new verion of TeeChart is not supported by ActiveReports?

Appreciate any help.

Hello AMC,

I couldn't reproduce your problem using last version of TeeChart .Net and last version of ActiveReport6. Please you could send us a simple projecte because we could reproduce your problem here?


Thanks,

This is reply from DataDynamics for my question:

We are aware that the new version of Tee chart (4.0.2009.42283) does not render on Active Reports. The older version of the component used to work fine for our customer, apparently they have changed something which has made it incompatible. We have opened Case 142427 for further investigation. I have added your email under the list of affected customers.

And I found a workaround, maybe it helps you to determine a cause of the problem.
If set Graphics3D.BufferStyle property to none Steema.TeeChart.Drawing.BufferStyle.OptimizedBuffer (default value),
then all works well.

Hello AMC,

If set Graphics3D.BufferStyle property to none Steema.TeeChart.Drawing.BufferStyle.OptimizedBuffer (default value),

BufferStyle is a new property there are in last v3 and last v 4 of TeeChart .Net. I recommend that see next link, where explain because it was created double buffer and what are their advantages.

Also, you could take a look in manual help, concretely search Steema.TeeChart.Drawing\Graphics3D\BufferStyle property or Steema.TeeCahrt.Drawing\BufferStyle I suggest see last. Please, could you send us a simple project, because we could test and investigate problem in latest versions of TeeChart .Net?


Thanks,
