I had been trying to figure this out why I could not delete from my GridDataControl, bound to a DataTable, without it crashing with the error "Object reference not set to an instance of an object." for the longest and I decided to implement a new class built with the basic DataGrid. I used the same coding and it worked. So I go back to the Syncfusion control to try to make it work but with no success. So I ran the demo that came with the software DataGrid->Data Binding->Data Table Demo and tried to delete a record and it crashed. No other demo crashed, only the one bound to a data table. So my question is, is this a bug? Why is this happening?
And btw, none of my objects are null the null object is being found inside the GridDataControl but of course I can't debug it.but here is the stack trace below...
Thank you in advance for your response.
