Remove all rows

 Hi everybody

  //Grid.GetRows()->Clear();
  Grid.GetRecords()->RemoveAll();

  for(int i=0; i<CustomerList->Count; i++) {
    Grid.AddRecord(CustomerList->InternalList);
  }

  Grid.RedrawControl();
  Grid.Populate(); 

I like to remove all rows of the Grid before inserting new ones.

At the beginning, when the grid is clear, all works
If the grid has already rows, so it removes all rows & records ( verified with GetCount )

But at Grid.Populate(); it has an error

Thanks
