Hi Gourav,

Thank you for your details and screenshot.

Are you customize the Esc Key in any event handler and handling the dispose?

Could you please try reproducing the ObjectDisposeException in any one of the browser sample or send us the reproducing steps so that we could sort out the cause of the issue and provide you a solution?

Thank you for using Syncfusion Products.

Hi Jeba
Thanks for your solution , but sorry i did mistake while writing this query . the mistake is that i am not pressing Escape key 3-4 times Continously.
The Issue is if i closed my GraphForm by pressing Escape Key , then after again opening and closing 3-4 times , my form throws Exception as mentioned already(In attachment).

Hi Gourav,

Thank you for your details.

Could you please provide more detials on how you are closing the GraphForm by pressing Escape Key ?

Are you handling Key down event like this?

 private void Form1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Escape)
                this.Close();
        }

I would really appreciate it if you could provide us a sample code that exhibits this behavior.

Thank you for being patient.

Best Regards,

Hi Gourav,

Thank you for your code snippets and attachment.

I am afraid that I was not able to reproduce the issue. I have created a sample to test this issue and it is available in the following link:
http://websamples.syncfusion.com/samples/Chart.Windows/F67471/main.htm

Please have a look at the above sample and if still the issue exists, could you please try reproducing it in the above sample or send us the reproducing steps so that we could sort out the cause of the issue and provide you a solution?

Please refer the tested video file:
