DataGrid throwing exception

[Shridhar Guravannavar]

I am using Syncfusion DataGrid and it throws following exception during runtime (without any user action).

Please let me know what could be wrong...

Hi Shridhar,

Could you please check if this exception thrown was due to any of the reasons that are detailed in this KB article.

Best regards,

Thank you for your response.

I am not sure if that patch would fix the problem I am having because the datatable does not contain any calculated columns.

The article you mentioned specifically says that the patch will fix the exception appearing with datatable that has calculated column in it.

What else could be wrong ?

Hi Shridhar,

Are there multiple threads involved in your appilcation? If so, please check the Knowledge Base(KB) article link below.

http://www.syncfusion.com/support/kb/grid/Default.aspx?ToDo=view&questId=78

Intermittant errors can be indications of threading issues. Any calls into the grid must be done on the thread that creates it, and you can use grid.InvokeRequired to check for this.

If you still face the same issues, please send me a working sample so that we may work on it here for you.

Best regards,
Haneef
