I have a sort functionality on clicking DW headers. There is one column which has code value and display values. When sorting it is sorting on code values, but i need to sort on display values.

Any suggestions??

Thanks in advance

The answer most likely lies in the following function;

Description

Obtains the display value in the code table associated with the data value in the specified column.

Syntax

LookUpDisplay ( column )

Argument      Description
column      The column for which you want the code table display value
Return value

String. Returns the display value when it succeeds and the empty string ("") if an error occurs.

Usage

If a column has a code table, a buffer stores a value from the data column of the code table, but the user sees a value from the display column. Use LookUpDisplay to get the value the user sees.

Hello Lordain,

Do you know if it is possible to use the LookUpDisplay function within a datawindow SetSort function? For instance, dw_v.SetSort("LookUpDisplay(column9) A")?

The sort seems to always use the DataColumn value rather than the DisplayColumn when actually executing the sort. When I add code to the window to view the actual data in the dropdowndatawindow using Describe, it is correct, and I can also use the LookUpDisplay fuction to pull the values from the child dddw and see them in a log file generated when running the window, but the sort seems to ignore the LookUpDisplay function.

Thanks for any advice.
