Argument	Type	Description
row	N	the row that needs a refresh

Details

This method is only available if Putrow Options in the Attributes window is set to Run getrow for all modified rows or Do not run getrow. When either of these options is set, the number of GETROW refreshes is limited. However, there are times when a row needs to be refreshed but the process is prevented by these options.

For example, suppose an extended table consists of protected text-entry objects. The table is being used for displaying information so none of the rows can be modified by the user. In this case, the option, Do not run getrow is enabled. However, if the information being displayed in the table is retrieved from a data set and the application modifies a specific observation in the data set, then the row corresponding to that observation needs to be refreshed.

Refreshing of the row does not occur immediately but rather occurs when the table receives a _refresh method. See Flow of Control in Extended Tables for more information on _refresh.
