Updating a cell programatically

[Bob]

I'm trying to update a cell in code, but get this error:
DataTable internal index is corrupted: '13'.

My code to perform the update is:
RadGridView1.Rows(rowNum).Cells(cellNum).Value = "12"

What could be going on here?  Stack trace below:
System.InvalidOperationException was unhandled
  Message="DataTable internal index is corrupted: '13'."
  Source="System.Data"
  StackTrace:

 I can help you reproduce this error is by following steps.

1. Grid with column1, column2, column3. Load some values into datatable
2. Create 2 timers and see that  you start the timer when executed.
3. Timer1_Event: Update column1 rows randomly.
4. Timer2_event: Update Column2 row randomly.

 The error occurs when for a given row example row2[Column1] being edited by Timer1_event and at the same time row2[Column2] being edited by Timer2_event causes this error. This error exists from Framework 2.0.
