Hi Vivek,

Thanks for your interest in Syncfusion products.

Regarding Expression field column, it provides the values based on the calculation expression involving numeric values of type int,double,etc., Hence the ResultType must be compatible with the expression. If it is not, NullReferenceException will be thrown.

If you still see the issue, please send the sample which reproduces this issue so that we could try to sort out the cause for this issue and provide you with a solution.

Regards,
Rajadurai
