      for ( int i = 0; i < myTable->Rows->Count; i++ )
      {
         if ( myGrid->IsExpanded( i ) )

protected void TextExpanded(DataGrid myGrid){
    // Get the DataTable of the grid
    DataTable myTable;

    myTable = CType(myGrid.DataSource, DataTable)
    Dim i As Integer
    For i = 0 To myTable.Rows.Count - 1
        If myGrid.IsExpanded(i) Then
