  Hi Malishin,

  Rows’s Remove method only removes the row from the FlexGrid’s rows collection. Therefore, in order to delete a row from the data source you have to delete it from the FlexGrid’s CollectionView as follows:

  
  int rowIndex = flexGrid.Selection.TopRow;
  var dataItem = flexGrid.Rows[rowIndex].DataItem;
  (flexGrid.CollectionView as ListCollectionView).Remove(dataItem);
  

  Best Regards,
