Serialize Chart

[Des]

I'm unable to serialize the chart template. I get the below error.

Stream stream = new MemoryStream();
...Chart.Export.Template.Serialize(stream);

"Type 'Steema.TeeChart.WPF.Drawing.Graphics3DWPF' in Assembly 'TeeChart.WPF, Version=4.2019.5.15, Culture=neutral, ... is not marked as serializable."

Hello -

The following code running with TeeChart.WPF.dll v.4.2019.5.15 works as expected here:

Code: Select all

        private void TChart1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
        {
            var ms = new MemoryStream();
            tChart1.Export.Template.Save(ms);
            ms.Position = 0;
            tChart2.Import.Template.Load(ms);
        }

Could you please post a code snippet with which we can reproduce your issue here?
