protected virtual void NotifyCurrentCellChanged() { TraceUtil.TraceCurrentMethodInfoIf(Switches.CellRenderer.TraceVerbose); CurrentCell.NotifyChanged(); }Is CurrentCell null? If you own the source code for our libraries, you can use the Assembly Manager (found on the Syncfusion Start menu) to build a debug version of the libraries. Then if you set the debugger to break on exceptions, you should be able to step into the code to see eexactly what is null, and hopefully track down what needs to be done to avoid it. If you can post a sample project showing the problem, we can try to do this debug work here.
