  Hi,

  Thanks for providing the sample and snapshots.

  You need to finish editing before modifying collection source of flexgrid. In your scenario, Collection is modifying without exiting from the edit mode.
  
  You can end edit before Reload as:

  
  	 grid.FinishRowEditing();
           _model.Reload();
  
  

  Please refer the attached modified sample for the same : FlexGrid_OutOfRange_Mod.zip

  Best Regards,
  
  Nitin
