Ordering Lookup Entries

Description

  1. Select the control that will display the list, right click, and select Properties... .

  2. On the Setup tab select "Combo Box" in the Field-Type list.

  3. Display the Choices tab.

  4. Select "Computed Automatically" in the Choices for control are list.

  5. Select "Expression (that returns a CR-LF delimited list) in the Source list.

  6. Enter an expression similar to the following in the Expression field.

    table.external_record_content_get("", "", "")

In this particular example, the table contains the following values.

Sequence Field
Display Field
"a"

100

"f"

1000

"g"

1250

"h"

1500

"b"

200

"i"

2000

"c"

250

"j"

2500

"d"

When the user clicks the combo box, the following list appears.
