Hello BeijerElectronics,

Ok. Using last version of TeeChart.Net and next lines of code, I can not reproduce your exception:

Code: Select all

    private void  InitializeChart()
        {
            tChart1.Aspect.View3D = false;
            Steema.TeeChart.Styles.Donut donut1 = new Donut(tChart1.Chart);
            donut1.FillSampleValues();
            tChart1.Dock = DockStyle.Fill;

}

Can you please,tell us if using previous lines of code your problem appears? On the other hand, can you tell us which version of TeeChart.Net are you using now?

Thanks,

We can reproduce the crash in the latest version with the following slightly different call stack:

Hello BeijerElectronics,

You are right! Finally I can reproduce your problem and I have added your request in bug list report with number [TW16015817]. We will try to fix it in next maintenance releases of TeeChartWPF.
