Object reference not sent to an instance of an object.

Hello,

It is possible that this error occurs when using DataGridView. Updating the datagrid from multiple threads will cause Red X to send an error. DataGridView is not a thread-safe. Besides, this is a Microsoft.Net control and needs C# compiler to build it. The build is necessary in order to override the event of method paint(). After you build .Net class, use OpenSpan Studio Toolbox to replace the DataGridView controls. Check the example provided in RedX.txt file.

 

I hope this is useful.
