You can use the DataColumnCollection of Your datatable to check if the column is in the collection.

Something like:

DataColumnCollection Columns = dtItems.Columns;

if (Columns.Contains(ColNameToCheck))
{
  row["ColNameToCheck"] = "Checked";
}

You should try   if  row Table Columns Contains  US OTHERFRIEND      I don t believe that row has a columns property itself

if  drMyRow Table Columns  ColNameToCheck      null       doSomethingUseful    else   return      Although the DataRow does not have a Columns property  it does have a Table that the column can be checked for
