issue regarding TeeChart rendering

[Amol]

Hi Steema Support,

We are facing one issue regarding TeeChart rendering. We are using the Dot Net TChart version 2012.
The problem is that when we show/open a chart on Window form as dialog, first time form opens correctly.

When we close the dialog and again reopens it (without creating the new instance of the form), we got crash on teechart.

Hello,

Okay, I have been able to reproduce this issue in the latest source code. I'm not yet entirely sure why it happens, but certainly the problem can be mitigated with the following code.

Code: Select all

private void Form2_FormClosing(object sender, FormClosingEventArgs e)
{
     tChart1.Chart.Graphics3D.BackBuffer = null;
}
