Error ''There is no row at Position..''

Hi I have the SyncFusion Grid ver 2.0.5.1, I used GridDataBoundGrid Control, for some condition i bound some set of record in the grid as dataSource = dataSet1.Table[0]; And i placed my focus to some of the row position. Then update the grid rows to my back-end table and the grid to be cleared by clearing the dataset. Continuously i bound another set of record to that grid it throughs error ''There is no rows at Position (0/1/3..)''. I need the solution. Thanks in advance Regards Chandru.

I am trying to see the problem in the attached sample that has button handlers that clear a DatSet and reload a table. Can you see the problem in this sample, maybe modify it to show the problem? ClearDataSet_1414.zip
