Yes here is a example I threw together. I have a large tree with a lot of nodes and child nodes. I am using Syncfusion Version 3.2.1.0 with .NET 2003 1.1.
There is a context menu so to duplicate the error:
1. right click and choose collapse all
2. right click choose expand all
3. Do not move the vertical bar back up to the top just right click and choose collapse all and you will get a execption thrown.
Thanks again John
>Hi John,
Thank you for your details.
I am afraid that I was not able to reproduce the "NullReference Exception". I have created a sample to test the issue and it is available in the following link:
http://websamples.syncfusion.com/samples/Tools.Windows/F64988/main.htmPlease 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 and screen shot so that we could sort out the cause of the issue and provide you a solution?
Please provide us your Syncfusion version and .Net version details.
Thank you for using Syncfusion Products.
Best Regards,
Jeba.
