If the column you are reading has the potential for a NULL value, then you must use the DBNull object:

DataRowView dRowView = m_SchedCommentsBindingSource[0] as DataRowView;

dsL2DB.SchedulesRow SchedRow = dRowView.Row as dsL2DB.SchedulesRow;

sDeleteComment = (SchedRow["DeleteComment"] == DBNull.Value ? "No Delete Comment" : SchedRow.DeleteComment);


More generically:


If (ds.Rows[0]["ColumnName"] == DBNull.Value)


// Do something for NULL value
